BR Chapter 12: Fit Criteria and Rationale

A satisfying viewpoint (among a large number) of Kent Beck's eXtreme Programming system is its emphasis on composing experiments before composing the code. The experiment characterizes the measuring stick that the executed code must match. The fit model is pretty much something very similar: It is a measuring stick for the necessity. By adding a fit rule to the necessity, you are, basically, composing its experiment. In the event that you are utilizing client stories, at that point we firmly propose that you give specific consideration to the explanation given for the usefulness. This is pretty much equivalent to the justification, and is a significant supporter of winding up with the right item. Composing experiments on the back of the story card ought to accomplish a similar reason as the fit standard we talk about here.  For each of the non-practical necessities yielded by the blog, we presently propose determining the fitting fit rule, affirming it with the partner, and compo...

BR Chapter 11: Non-functional requirements

Functional versus Non- functional requirements: Non-functional requirements do not alter the product’s essential functionality. That is, the functional requirements remain the same no matter which properties you attach to them. At the risk of confusing matters, the non-functional requirements might add functionality to the product. In the security example, the product would have to do things to make certain that only supervising engineers alter the data, but that functionality is needed for a non-functional reason—in this case, security. Perhaps it is easier to think of the functional requirements as those that cause the product to do the work and the non-functional requirements as those that give character to the work, and even easier to say that functional requirements are verbs and non-functional requirements are adjectives. Non-functional requirements make up a significant part of the specification. Provided the product meets the required amount of functionality, the non-functi...
