1、 Developing Techniques for Using Software Documents: A SeriesDeveloping Techniques for Using Software Documents:A Series of Empirical StudiesPh.D. Thesis ProposalForrest J. ShullUniversity of MarylandAbstractThis proposal presents an empirical method for developing reading techniques; that give effe
2、ctive,procedural guidance to software practitioners. Each reading technique is tailored so that it can be used toaccomplish a specific software-related task (e.g. defect detection) using a specific kind of softwaredocument (e.g. requirements). This empirical method can be followed to create and then
3、 continuallyimprove reading techniques, since it explicitly builds and tests underlying models of how developers use aparticular software document in a particular environment. That is, our approach for developing readingtechniques checks the underlying assumptions about:· Specific tasks for w

5、ch they have not been tested.We illustrate the development method by discussing how it was used to create two readingtechniques (one for finding defects in requirements, and a second for reusing design and code from anObject-Oriented framework in a new system). We describe a series of studies by whi

These studies showthat these reading techniques are useful and effective guidelines for accomplishing real softwareengineering tasks, and thus demonstrate the effectiveness of the empirical develo
7、pment method.Finally, this proposal discusses how indications from these studies have been used to begin toformulate higher-level hypotheses about reading techniques. We discuss the results from these earlierstudies as well as important questions that have not yet been addressed. We propose a furthe

It presents an iterative process for creat

We refer tothis process simply as the Reading Technique Development (RTD) process. As will be explained ingreater detail in the rest of this chapter, reading techniques created by the RTD process pr
