One of the fundamental objectives of any project is to collect both the functional and non-functional requirements. These need to be kept in balance and harmony, and most importantly not compromised as the project progresses, as happened with Titanic's construction project. This project was so compromised in its design, construction, and delivery it was destined to fail. The compromises started early in the project with the requirements, particularly with the non-functional requirements.
Thomas Andrews was one of the principal architects of the three White Star super liners, and accountable for turning the project sponsor's vision into reality. He was also the project leader/manager. Involved from the outset of the Olympic-class ship project he took responsibility for the requirements, both functional and non-functional.
The official definition for a functional requirement specifies what the system should do:
"A requirement specifies a function that a system or component must be able to perform."
Functional requirements specify specific behavior or functions, for example:
"Display the heart rate, blood pressure and temperature of a patient connected to the patient monitor."
The official definition for a non-functional requirement specifies how the system should behave:
"A non-functional requirement is a statement of how a system must behave, it is a constraint upon the systems behavior."
Non-functional requirements specify all the remaining requirements not covered by the functional requirements. They specify criteria that judge the operation of a system, rather than specific behaviors, for example:
"Display of the patient's vital signs must respond to a change in the patient's status within 2 seconds."
Non-functional requirements specify the system’s ‘quality characteristics’ or ‘quality attributes’. Potentially many different stakeholders have an interest in getting the non-functional requirements right. This is because for many large systems the people buying the system are completely different from those who are going to use it (customers and users).
This matrix is used to trace project life cycle activities and work products to the project (or business) requirements. The matrix establishes a thread that traces all requirements from identification through to implementation, that is business requirements to system requirements and if necessary component requirements. Traceability is Bi-directional and so is used to manage change and provides the basis for test planning. Traceability tracks the allocation of each requirement to the following:
Functional testing is concerned with the functional requirements and covers how well the system executes its functions. These include testing of:
Non-functional testing is concerned with the non-functional requirements and is designed to evaluate the readiness of a system according to several criteria not covered by functional testing. It enables the measurement and comparison of the testing of non-functional attributes of software systems.
and also Miscellaneous Testing such as:
Testing does not have to occur once the 'code' has been delivered. It can start early with analyzing the requirements and creating test criteria of 'What' you need to test. The process for doing this is called the “V” model. It decomposes requirements and testing. Because it allows testing and coding as a parallel activity which enables the changes to occur more dynamic.
The cost of catching and correcting errors early in the cycle is generally under 20% of the cost post implementation.
