2. What have the authors stated for future works in "Method construction by goal analysis" ?

3. What is the way to improve the quality of a project?

4. What kind of input is needed to create a requirements specification document?

Accepted Answer

This paper presents a goal analysis technique for the selection of the optimal method fragments from a repository, using backward reasoning to obtain the set of fragments that satisfy the desired goals with minimum effort.

Accepted Answer

The authors are currently planning such industry trials within the Italian ministry funded project MEnSA ( http: //www. mensa-project. org ) project and anticipate building appropriate support tools in due course.

Accepted Answer

In order to provide the necessary input (i.e. a requirements specification document), the authors need to select a task kind that creates it, namely “Document Requirements”.

Accepted Answer

In particular, contribution analysis has been shown to be very effective for soft goals used for eliciting non-functional (quality) requirements.

Accepted Answer

Factors that influence these requirements are many, including organizational maturity level, skills set of development team members, type of domain (e.g. information systems, realtime control, e-business), project size, team size, level of criticality, interface style, level of resources allocated to project and whether or not the system is to be a distributed application (Nguyen and Henderson-Sellers 2003)Table 5 shows a list of the attributes that the authors have identified for the purpose of illustration in this paper.

Accepted Answer

Goal analysis has been used in a number of ways to support software development e.g. in the design of systems, especially for documenting early requirements, as in the Tropos methodology (Bresciani et al., 2004); in business process reengineering (Grau, Franch, and Maiden 2005); and in the support of ISO/IEC15504 assessments (Rifaut, 2005).

Accepted Answer

Each of these work product kinds would be associated to a number of task kinds with a particular action type; for example “Requirements Specification Document” can be mapped to “Document requirements” via an action kind with a “create” type and to “Develop service models” via a different action kind with a “read” type.

Accepted Answer

The authors are aware that many other attributes (such as product correctness or readability) are alsoMethod Construction by Goal Analysis 7of interest to software engineering, but they have been left out from this experiment since they are not likely to be directly affected by the choice of method fragments.

Accepted Answer

Rather than select the elements of the methodology “top-down” by considering what seems reasonable in a particular situation using what might be termed “intuition” (the current approach in SME), the authors suggest that a more objective process can be created in which the main focus becomes the goal rather than the means of achieving that goal (the process element).

Accepted Answer

an organisation willing to adopt the method engineering paradigm will need to recruit a methodologist or hire a consultant to compose a methodology each time.

Accepted Answer

The goal analysis approach proposed here permits the creation of an optimized methodology; importantly, one that is optimized for a particular characteristic such as reliability or agility.
