It is difficult to disagree with such thesis. However, some of the decisions are not directly driven by NFRs, but by the functionality of the system. It can also happen that some of the NFRs are not explicitly defined. In this entry, you can find a checklist containing 20 questions regarding functional requirements that can help you investigate required capabilities of a system architecture.

You can reduce this number by introducing the CRUD pattern, which I would like to present you in this blog entry.

It is based on two main inputs which are actors complexity, measured based on the interface actor uses to communicate with the system; and use-case complexity measured in the number of so-called transactions in use-case scenarios. Here, I would like to present you basic information about the original method proposed by Karner.

Although they are in most cases presented in a textual form, there is a special diagram in UML called Use Case Diagram (UCD), which is used to present their structure and associations with actors. In this article I will try to present you all necessary information to use UCD effectively.

The ideal case is XP s on-site customer. Unfortunately, in practice customer representatives are too busy to work with the development team all the time. Moreover, frequently there are many of them and each representative has only partial domain knowledge. To cope with this we introduced to our projects a proxy-customer role resembling RUP s Analyst and we equipped him with a tool, called UC Workbench, that supports the communication with the customer representatives and the developers. Analyst collects user stories from customer representatives and translates them into use cases. UC Workbench contains among other things a use-case editor and a generator of mockups (a mockup generated by UC Workbench animates use-cases and illustrates them with screen designs).

Each use case contains a sequence of steps which are described with a natural language. Use cases, as any other description of functional requirements, must go through a review process to check their quality. The problem is that such reviews are time consuming. Moreover, effectiveness of a review depends on quality of the submitted document - if a document contains many easy-to-detect defects, then reviewers tend to find those simple defects and they feel exempted from working hard to detect difficult defects. To solve the problem it is proposed to augment a requirements management tool with a detector that would find easy-to-detect defects automatically.

Gwałtowny wzrost popularności zaawocował wieloma różnymi podejściami do ich prezentacji oraz stylami ich pisania. Niestety, ta różnorodność sprawia, że automatyczne przetwarzanie przypadków użycia jest bardzo trudne. Ten problem może być zniwelowany poprzez wykorzystanie koncepcji transakcji, która jest zdefiniowana jako atomowej część scenariusza przypadku użycia.  W artykule prezentujemy podejście do automatycznego wykrywania transakcji w przypadkach użycia, poprzez analizę języka naturalnego (NLP). Proponowane rozwiązanie zostało zaimplementowane w postaci prototypowego narzędzia UCTD i wstępnie zweryfikowane.
