The system needed to deliver benefits for the fishermen and the authorities to create a win win situation within a tight budget. With approximately 15,000 fishing boats, thousands of kms of coast line and an EEZ (exclusive economic zone) extending to tens of thousands of square kilometres there were a number of challenges to overcome. The authority had pre-determined that Automatic Identification System (AIS) technology offered the optimal combination of reliability, functionality and cost and above all was an IMO approved and sanctioned vessel tracking technology. Our customer support team worked with the customer and the authority to create a system specification which would deliver the required functionality. As is normal with large national systems, one of the major challenges was the inability for AIS Coast Stations to be installed along the entire coast due to geographical challenges which made this impractical. Also various islands and headlands created reception black spots. This was overcome through the deployment of ABSEA enabled Identifier AIS Transceivers which enabled a percentage of the transmissions to be detected from the exactEarth AIS satellite network and fused with data collected from the terrestrial based coast station network. SRT created a modular system solution for the customer made up of: ABSEA enabled Identifier AIS Transceivers, with internal VDR functionality, to be securely fitted to each boat Coast Stations to be installed wherever practical along the coast line to receive all AIS transmissions within range of the antenna in real time A feed of satellite data, containing live and recent history location information with a once every 4 hour update rate The GeoVS-HUB database solution to receive, process and store all information from coast stations and satellite A range of GeoVS VIEWER licenses which enable the data to be viewed in real time on 2D charts and in enhanced real time 3D digital reality The architecture of the proposed system will allow the customer to build their system gradually over time in accordance with their annual budgets. The first step has been to complete a small installation to prove and characterise the system which was followed by the commencement of the national rollout. The customer benefited from our expertise in AIS technologies and MDA systems coupled with access to a complete range of products which were used to build the specific customised solution their national authority wanted. The availability of ABSEA enabled satellite AIS data at a fraction of the cost of traditional non AIS satellite technologies was a critical system differentiator as it enabled the authority to monitor any fishing vessel fitted with a transceiver across their entire EEZ. AIS Satellite Tracking ABSEA (Advanced Class B Satellite Enabled AIS) provides the ability to track any vessel equipped with a special Automatic Identification System (AIS) identifier created with unique technology from our partners at SRT Marine System Solutions. The transmissions from these unique identifiers will be reliably received by the exactEarth global satellite network. For more information about ABSEA or the Identifiers, please contact our sales team at: infomaritec.co.za AIS is a Very High Frequency (VHF) technology primarily optimised and designed for high intensity terrestrial-based tracking with reliable range typically limited to approximately 50 nautical miles. High powered Class A type transceivers are able to be tracked globally by the existing exactEarth AIS satellite network, however due to a variety of complex reasons, transmissions from standard Class B and Identifier type devices cannot currently be reliably tracked from space. The reception of Class B units from space has been traditionally hindered because Class B units are designed to always show deference to Class A devices. Class B units transmit less frequently at a lower power level. As Class A populations increase within a satellite footprint, the Class B transmissions become indistinguishable from the general noise floor. By utilising patented Satellite AIS techniques coupled with SRT technology, ABSEA allows terrestrial and satellite tracking of these small vessels without requiring expensive equipment and per-bit message charges for the ship owner. exactEarth and SRT have now developed a unique technology called ABSEA which, when embedded within these standard low-powered AIS transceivers, enables their transmissions to be consistently received by exactEarth satellites. This allows wide-area tracking of these vessels and also enables the provision of valuable supplementary AIS tracking data to existing terrestrial networks with limited coverage. Combining the efficiency of SRT8217s em-trak Identifier with the most advanced Satellite AIS technology available, ABSEA represents the most cost-efficient and comprehensive solution to monitor all of the worlds shipping, regardless of vessel size and location. The first ABSEA-enabled products are expected to be deployed later this year.I8217ve been accused of being a shell designeryou start with a machine and enclose it. But in many cases, the shell is essential. A locomotive without a shell would be nonfunctional. Nonfunctional Requirements Abstract Nonfunctional Requirements (NFRs, or system qualities) describe system attributes such as security, reliability, maintainability, scalability, and usability (often referred to as the ilities). They can also be constraints or restrictions on the design of the system (in which they may be referred to as design constraints ). These requirements are just as critical as the functional Epics, Capabilities, Features, and User Stories, as they ensure the usability and efficacy of the entire system failing to meet any one can result in systems that do not meet internal business, user, or market needs or that do not meet mandatory requirements imposed by regulatory or standards agencies. Nonfunctional requirements are persistent qualities and constraints and, unlike functional requirements, are typically revisited as part of the Definition of Done for each Iteration, Program Increment, or Release. NFRs exist at all four SAFe levels: Team, Program, Value Stream, and Portfolio. Definition and implementation of NFRs is of critical concern for the system builder. Over-specify them and the Solution may be too costly to be viable under-specify them and the solution will not be adequate for its intended use. An adaptive and incremental approach to exploring, defining, and implementing NFRs is a key skill of the successful Lean-Agile system builder. Traditionally, one way to think about all the types of requirements that affect a Solution8217s overall fitness for use has been the acronym 8220FURPS,8221 which is a traditional requirements categorization for Functionality , Usability , Reliability , Performance . and Supportability 5. Functional requirements are largely expressed in User Stories and in Features and Capabilities. This is where most of the work occurs: Teams build systems that deliver functional value to the user, and a majority of the time and effort in solution development is devoted to that functionality. FURPS is the placeholder for Nonfunctional Requirements . Though they may be a bit more subtle, NFRs are as just as important to system success as are functional requirements. NFRs can be considered constraints on new development, in that each eliminates some degree of design freedom on the part of those building the system. For example: We need to implement SAML-based single sign-on for all products in the suite (SSO is a functional requirement basing the technology on SAML is a constraint ). NFRs can cover a wide range of business-critical issues that are not well addressed by functional requirements. As a reminder to system designers, a fairly comprehensive list of such potential requirements is described in 1. NFRs Occur at All Levels Nonfunctional requirements are associated with backlogs at all four levels of SAFe, as Figure 1 illustrates. Because NFRs are significant attributes of the solution that the Agile Release Train and Value Streams create, the most obvious representation of NFRs are at the Program and Value Stream Levels. System and Solution Architect and Engineering are often responsible for defining and refining these NFRs. All teams must be aware of these special attributes of the system they are creating. This helps foster Built-in Quality practices by accelerating NFR testing, rather than postponing it. Teams include the relevant NFRs into their Definition of Done, use them as constraints on local design and implementation decisions, and take responsibility for some level of NFR testing on their own. Otherwise, the solution may not satisfy key NFRs, and the cost of correction can be very high when it occurs late in the process. In addition, Team Level NFRs can also be important, as they create constraints and performance requirements on the features and subsystems they create. The Portfolio Level may require certain NFRs as well. This is often the case for inherently cross-system qualities, like the single sign-on example. Other examples include restrictions on open source usage, common security requirements, regulatory standards, and more. If a specific portfolio level NFR is not yet achieved, it may require architectural Enablers to implement it. In other cases, portfolio level NFRs may naturally appear on business and enabler Epic success criteria. NFRs as Backlog Constraints In SAFe, NFRs are modeled as 8220backlog constraints,8221 as is illustrated in Figure 2. More technically, the SAFe Requirements Model specifies that NFRs may constrain zero , some . or many backlog items. Further, in order to know that the system is compliant with the constraint, most NFRs require one or more system qualities tests, as is illustrated in Figure 3. Many NFRs begin their lives as enablers that need to be addressed. Thereafter, they constrain the system and all new backlog items going forward. The Systemic and Economic Impact of NFRs on Solution Development Nonfunctional requirements can have major impact on solution development and testing. NFRs are tricky to specify, and it8217s easy to go overboard. For example, a statement like 99.9999 availability may increase development effort by one or two orders of magnitude more than 99.999 availability. Sometimes that8217s necessary and other times it8217s not, but the impact of the NFR must be well understood by those writing the specifications. Similarly, physical constraints such as weight, volume, or voltage, if not given enough thought, may cause the solution to be overly complicated and too costly. The Economic Framework of the solution should hold criteria to evaluate the extent to which NFRs should be taken as a trade-off with costs and other considerations. Suppliers are likewise impacted by NFRs, and declaring them incorrectly or without the full trade-off ramifications of the economic framework might lead to unnecessarily complex and costly systems and components. It is also important to reevaluate NFRs regularly. Unlike other requirements, NFRs are persistent constraints on the backlog, rather than backlog items themselves, and so they may not always come up during PI Planning. But nonfunctional requirements do change during development, and system builders must be well aware. NFRs and Solution Intent Solution Intent is the single source of truth about the solution, and as such it includes NFRs as well as functional requirements. It also includes links between NFRs, requirements they impact, and tests used to verify them. NFRs play a key role in understanding the economics of fixed versus variable solution intent. Early on, some of the functionality is not clear and will need to be tested and negotiated with Customers during development. The same goes for NFRssome are fixed and well known up front, while others will evolve with the solution. By imposing constraints, NFRs may impact a wide scope of system functionality. Therefore they are an important factor in Agile analysis: Analyzing business epics, capabilities, and features Planning and building the Architectural Runway Refactoring to better reflect increasing solution domain knowledge Imposing DevOps constraints by manufacturing, deployment, support, installation, maintainability, etc. The tools used to help develop solution intent provide some mechanisms to help establish an economic approach to defining and implementing NFRs. Agile Architecture A solid intentional architecture supports development of NFRs and helps maintain flexibility as they change Model-Based Systems Engineering Models can be used to simulate the effect of NFRs and can link to the tests that validate them Set-Based Design SBD provides different frames for achieving NFRs and can guide a range of edge-case testing in support of design decisions Specifying NFRs Defining NFRs is assisted by consideration of the following criteria: Bounded. Some NFRs are irrelevant (or even impairing) when they lack bounded context. For example, performance considerations can be extremely important for the main application but irrelevant (or too expensive) for administration and support applications. Independent. NFRs should be independent of each other so that they can be evaluated and tested without consideration of or impact from other system qualities. Negotiable. Understanding the NFR business drivers and bounded context mandates negotiability. Testable. NFRs must be stated with objective, measurable, and testable criteria, because if you can8217t test it, you can8217t ship it . Implementation Approaches Many NFRs prescribe that some additional work be doneeither now or in the futureto satisfy them. Sometimes the NFR must be implemented all at once at other times the teams can take a more incremental approach. The trade-offs described in the economic framework should impact the implementation approach. Implementation should be built in a way that will allow several learning cycles to ascertain the right level of NFR. All at once. Some NFRs appear as new, immediate concerns and just have to be done now. For example, a new regulatory rule for derivative trading, if not immediately accommodated, could take the company completely out of the market or cause a regulatory violation. Incremental story-by-story path. At other times the teams have options. For example, the need for substantially improved performance can be dealt with over time, one story at a time, as Figure 5 illustrates. Figure 5. Introducing an NFR to the solution incrementallyNFR implementation is also impacted by the way ARTs have been organized. ARTs built around architectural layers will find it very hard to implement and test an NFR in its entirety. ARTs organized around capabilities will find it easier to implement, test, and maintain systemic NFRs. Testing Nonfunctional Requirements Of course, in order to know that a system meets NFRs, it must be tested against them. Testing NFRs is most easily viewed from the perspective of the four Agile testing quadrants . as reflected in Figure 6 2, 3. Figure 6. Agile testing quadrants (adapted from 2, 3) Quadrant 4, System Qualities Tests . is the home of most NFR tests. Due to their scope and criticality, NFR testing often requires collaboration between the System Team and the Agile Teams. Wherever possible, teams should automate so that these tests can be run continuously, or at least on demand, to help prevent the growth of unexpected technical debt. Over time, however, the accumulated growth of regression tests, even when automated, may consume too much resource and processing time. Worse, it can mean that NFR testing may be practical only on occasion, or only with specialty resources or personnel. In order to ensure practicality and continuous use, teams often need to create reduced test suites and test data, as is illustrated in Figure 7. Figure 7. Collaboration of the System Team and Agile Teams to create a more practical NFR testing strategy Though 8220partial testing8221 sounds less than ideal, it can actually be beneficial in increasing system quality: When teams are able to apply reduced test suites locally, they may spot inconsistencies in the test data or testing approach Teams may create new and unique tests, some of which may be adopted by the System Team to help build the larger set Testing infrastructure and configurations will likely be continuously improved Teams gain a practical understanding of the impact of NFRs, which helps improve estimating of business and architectural features Even so, in some cases the environment where the NFRs can be tested may not be available on a daily basis (example: field testing of vehicle guidance software). In these cases, the following approaches 4 can be used: Using virtualized hardware Creating simulators Creating similar environments In all cases, efficiently testing nonfunctional requirements requires some thought and creativity. A lack of NFR testing, on the other hand, may increase the risk of substantive technical debt or, worse, system failure. Learn More 2 Leffingwell, Dean.

What I have struggled to find, though, is a good, detailed description of what should actually go in an FS and, in particular, to what level of detail. When asked this question, most BAs answer, 8220it depends8221. Whilst this is true, I think we can improve on it by drawing some clear boundaries around how much detail is allowed, and how much is too much. Therefore, I present a specification for a functional specification. This my own view and by no means an industry standard, but it works for me. What Document are We Talking About Let8217s be clear. I8217m not talking here about a high-level business requi rements document or a wish-list of stakeholder needs that may or may not be achievable, and which might even conflict with one another. The document I8217m talking about here is the result of the synthesis of those needs into a coherent view of what the system will actually be. This is the document that you: Give to the developers so they know what to build Give to the testers so they know what tests to run Give to the stakeholders (and get them to approve) so they know what they are getting Now before you start getting all agile on me8230no, I8217m not advocating a 8220throw it over the wall8221 approach to delivery, and I8217ll talk later about the various forms that an FS can take. I just want to be sure we are all talking about the same thing. Oh, and whilst we8217re at it, let8217s not call it a document . It might not be a single monolithic text-and-diagrams epic. So let8217s just call it a thing . or even better, let8217s go plural: things. I8217m also primarily talking about the specification for a system that is to be built . Such a specification is not generally appropriate for a system that is to be bought off the shelf. A Simple Definition of a Functional Specification OK, now we have the preamble out of the way, here8217s my simple definition of a functional specification: A Functional Specification of a (computer) system describes the externally-visible behaviour of that system. That definition might sound a little too simple to be true. Surely there8217s more to a system than just what the users see. You8217re right, there is. And once I elaborate on my definitions of system and externally-visible behaviour (specifically, I don8217t mean just use cases), hopefully you will agree with me that the definition is both complete and precise. What is a System I like to think of a (computer) system as a black box. The black box has two interesting features: Interfaces . through which external entities can interact with the system via a series of inputs and outputs. There are two types of external entities 8211 humans and other systems (also collectively referred to as actors of the system), and we need to worry about them both. State . which changes as a result of interactions with the actors. Think of this as the system8217s memory, in which it remembers (or stores) data 8211 usually implemented as a database. This simple definition applies to pretty much any system you can think of. All systems have interfaces 8211 without any interfaces, a system is just a rather uninteresting black box Most systems have (human) user interfaces, but I8217ve also worked on plenty of data processing systems with no UIs 8211 they just take data from one system, process it, and pass it on to another system. Some systems do not have any system interfaces, but in these days of end-to-end integration, most systems do. Some very simple systems do not have any state, although most interesting systems do (any system that manages data has state). One of the most important things to get clear for a system under design is where the system boundary lies, and you can do that easily by identifying its interfaces with the outside world. Here8217s a simple diagram of a system (called eShop), showing its interfaces and the actors that use those interfaces. I call this a context diagram . An example context diagram Two Key Elements 8211 Functions and Data Armed with my definition of a system, I can now say that there are two key elements to a functional specification: Functions 8211 a description of the interactions between the system and its (human and system) actors Data 8211 a description of the state of the system Once you have described all the functions and all the data (to the right level of detail), you are done 8211 simple as that Describing Functions The functions of a system are the interactions that can occur between the system and its actors (through the interfaces). An interaction is a sequence of actor inputs (e.g. a user clicking a mouse button) and system outputs (e.g. displaying some data on the user8217s screen). Typically the actor is trying to achieve some objective (log in, search for data, update data, perform a calculation etc.). I like to use use cases as the main anchor for describing a system8217s functions. They are, to my mind, the perfect format for describing interactions between an actor and the system. Laura Brandenburg has a similar love affair with use cases. I8217m not going to explain use cases in full (you can click here to read what a use case is ), but just in case you8217re new to this game, a use case looks something like this: Use Case 1: User Logs On User launches the application System prompts user for log-on details (user name and password) User enters log-on details and submits them System requests user8217s log-on details from the external single-sign on directory System validates that user8217s entered log-on details match those from the directory System displays the main menu Alternative Flow 4a: Incorrect log-on details System tells user their log-on has failed Return to Main Flow step 2 Alternative Flow 4b: User account locked System tells user their account is locked and they should call the helpline Return to Main Flow step 2 I8217ve omitted some of the key parts of my use case for brevity (e.g. pre- and post-conditions), but you should be able to see that it describes the sequence of inputs (by the user) and outputs (by the system) for a given function. For more info on use cases, read Writing Effective Use Cases by Alistair Cockburn . Note that the example use case shows interactions both with a human user and also an external system (the single-sign on directory). In order for your use cases to be complete, you need to cover all the interactions through all the interfaces, whether they be human user interfaces or system interfaces, in particular including any 8220back-end8221 systems. It8217s also important to understand that use cases do not give a fully-detailed description of the system8217s functions. Rather, they are the anchor for the functions, around which the other details can be added. Adriana Beal has some additional comments on this topic in this article . Update 20102014 An alternative notation to use cases which is gaining popularity (especially in agile circles) is 8220gherkin8221 notation, also known as given-when-then scenarios, and strongly associated with Behaviour Driven Development (BDD) and Test Driven Development (TDD). As far as I am concerned, given-when-then scenarios are pretty much equivalent to use cases, as I discuss in this article . Functions 8211 How Much Detail is Allowed OK, we8217ve done the easy part 8211 most people agree that use cases rock, and all I8217ve been doing so far is setting the scene. The tricky part is deciding how much detail to include either within the use cases or alongside them. Here8217s my simple answer: You are allowed to include full detail of any externally-visible behaviour of the system (including behaviour through system interfaces). You are not allowed to include any details on the internal workings of the system. For example, you are absolutely allowed to include: User interface details, right down to the very last pixel and colour shade Size and allowable contents of data input fields Whether a specific input control is implemented as radio buttons or a drop-down menu Exact text of error messages Complex business rules and algorithms Supported web browsers, client operating systems, screen sizes Some people will argue that some of the above examples are aspects of the design . and have no place in a requirements specification. There8217s a long debate on this topic in my previous article, Requirements Versus Design: It8217s All Design . But whatever terminology we use, my experience is that business stakeholders, developers and testers care about these details, and thus they have every right to be included. In particular, the UX design might be put in a separate document, maybe even produced by a separate person (a UX designer), but in my world-view, it is still part of the externally-visible behaviour and thus part of this 8220thing8221 or 8220things8221 that I am calling a Functional Specification. Here are some more things you are allowed to include: Exact format of a system log Physical format of a system interface These are slightly more controversial because they are of little interest to our primary business stakeholders, and certainly have a 8220technical8221 aspect to them. Nevertheless, they are externally-visible behaviours of the system and are of interest to other stakeholders 8211 a sys admin, or the developers of an external system. Also allowed are the externally-visible qualities of the system, such as: Performance (system response times) Volumetrics (number of concurrent users) 8211 current and future Concurrency characteristics Security characteristics (notoriously difficult to specify effectively) Such qualities are commonly referred to as non-functional requirements 8211 a term which I really dislike because they are so obviously not non-functional. But the term is pretty-much ubiquitous, so I guess we8217re stuck with it. Describing Data First of all, let8217s resolve a contradiction. I8217ve said that the FS should describe the externally-visible behaviour of the system. But the system8217s state isn8217t externally visible (unless you go poking around in the database), so why include it The answer is that the system8217s state has an important effect on its functions. A function which updates the system8217s state has a delayed effect in that it affects any other function which outputs the same data. Functions and data are intertwined and you can8217t really describe one without the other. The usual way to describe system data is in terms of (logical) data entities. An entity is a 8220thing8221 of interest (a customer, an address, an order, a product). Entities have attributes (a customer has a first name, a last name, a date of birth etc.). Entities also have relationships with one another (a customer has one or more delivery addresses a customer has zero or more orders an order consists of one or more products). Data 8211 How Much Detail is Allowed Here8217s what detail I consider to be allowable for data: Entity name (so that it can be unambiguously referred to) Entity description (explaining what the entity actually is 8211 not always obvious) Attributes: Name Description (again, not always obvious) Type and allowable values, such as: String, max 50 characters Integer from 0 to 60,000 or blank One of Male, Female or Not Specified Relationships with other entities: Meaning of relationship (e.g. home address, delivery address) Multiplicity (one-to-one, one-to-many, zero-or-one-to-one etc.) Note that the above are logical, rather than physical, definitions. For example, a logical type of 8220Male, Female or Not Specified8221 might be implemented as a NUMBER where 1Male, 2Female, 0Not Specified, or it might be implemented as a nullable VARCHAR where 8220M8221Male, 8220F8221Female and NULLNot Specified Physical database definitions (table names, column names, column types) 8220Entities8221 that are actually database tables implementing many-to-many relationships OK, So How Much Detail Do I Actually Include So far, I have stated the level of detail that, in my view, is allowed in an FS. The obvious next question is whether you actually need to write down all that detail. And here8217s where we get back to the original answer 8211 8220it depends8221. It depends on a variery of factors, such as: How much your business stakeholders care about the details How much detail your developers want you to give (or alternatively how much you trust the developers to do something sensible in the absence of detail) How much detail your testers want you to give Whether you are specifying a new system or enhancements to an existing system 8211 an existing system has existing patterns which can be assumed to apply to enhancements, such as look amp feel, data validation rules and so on How much you rely on non-written communication My own experience is that every organisation is different, and for each new assignment I need to find the appropriate level of detail that needs to be written down. Here8217s what happens when I get it wrong: I give too little detail and the developers makes a 8220wrong8221 assumption I give too much detail and I spend more time than necessary writing it all down I give too little detail and the testers keep coming back for more detail I give too much detail and the developers and testers work exactly to spec instead of challenging its deficiencies However much detail I decide to include in, or omit from, my written specification, I am always clear where the boundary of my accountability lies 8211 I am accountable for all externally-visible behaviour of the system 8211 so if I choose to leave some detail out, I accept that I am giving the developers some free reign, but that it8217s my problem if the stakeholder doesn8217t like it And What Format Do I Write It Down In So far I have talked about a thing called a Functional Specification, and you might have assumed that I am thinking of a single, 8220traditonal8221 text-and-diagrams document (such a s might be authored in Microsoft Word). But of course there are many alternatives, especially when you start looking at agile approaches. Here are a few options: A formal requirements management tool, such as Rational Rose Use cases in a spreadsheet combined with an HTML prototype (see my previous article, An Agile Functional Specification ) Use cases, data and business rules in one document, UX design in a separate document (perhaps produced by a separate UX designer) User stories and acceptance criteria scribbled on index cards (as per XP) A graphical format using a drawing tool such as Microsoft Visio (something I am experimenting with at the moment) Regardless of the format used, the same rules about type of content and level of detail still apply. A Curveball or Two So far I have said that a functional specification should only describe externally-visible behaviour. I have already made a minor exception to this rule by including the system state, which is kind of internal. There are some other exceptions, and they apply in cases where it is important constrain the (internaltechnical) design of the system. Here are a couple of common examples: For a software product, defining the platform(s) on to which it must be possible to deploy the software (e.g. 8220compatible with Windows Vista and Windows 8 with 2GB of RAM8221) Extensibility requirements 8211 how easy it must be to extend or alter the system. This is a whole topic in itself. I try to treat these very much as exceptions to the rule and only include them where they are absolutely necessary. In Summary To summarise then: If a system is a black box with (human and system) actors interacting with it through interfaces, then8230 A functional specification describes the externally-visible behaviour of the system There are two key elements 8211 functions and data Functions are commonly anchored around use cases The theoretical scope includes all externally-visible behaviour, right down to the last pixel8230 But as to how much detail you actually include8230it depends8230 And you are still accountable for all the details that you omit Further Reading There8217s more to business analysis than just writing Functional Specifications.
