A primary actor is the main actor that initiates a use case UC for achieving a goal, and whose goal satisfaction is the main objective of the use case. Though itera- tions in construction are done often and it is clear what an iteration in this phase delivers, iterations may be done meaningfully in other phases as well.

The development process specifies all the engineering activities that need to be performed, whereas the management process specifies how to plan and control these activities so that cost, sched- ule, quality, and other objectives are met. As cost, schedule, and quality are the major driving forces, most of the activity of this phase revolves around monitoring factors that affect these. UCs where the scope is the enterprise can often run over a long period of time e.

Use cases are naturally textual descriptions, and represent the behavioral requirements of the system. Often we tend to teach too many concepts and topics in an introductory course resulting in shallow knowledge and little insight on application of these concepts.

An iteration starts with iteration planning in which the stories to be implemented in this iteration are selected—high-value and high-risk stories are considered as higher priority and implemented in early iterations. So, a project, if it so wishes, may do detailed requirements only for some features during the elabora- tion phase, and may do detailing of other requirements while the construction is going on maybe the first iteration of it.

RUP is a flexible frame- work which can allow a project to follow a traditional waterfall if it wants to, or allow prototyping, if it so wishes. Software Processes of requirements to be built in this iteration along with a high-level design. The basic purpose of this activity is to obtain a thorough under- standing of what the software needs to provide.

A project uses the timeboxing softwarre model with three stages in each time box introductiob discussed in the chapterbut with unequal length. Other approaches prefer that the requirements are specified precisely.

Based on the analysis, one of the tasks in the list can include redesign of defective components or redesign of the entire system.

The whole process of understanding the current process, analyzing its properties, determining how to improve, and then affecting the improvement is dealt with by the process skftware process.

For this section, different organizations have been suggested in the standard.

The effort spent in a subprocess in different phases will, of course, de- pend on the project. And if the information obtained by monitoring suggests that objectives may not be met, necessary actions are taken in this phase by exerting suitable control on the development activities.

Development of the prototype ob- viously undergoes design, coding, and testing, but each of these phases is not done very formally or thoroughly.

We will discuss this more later in the chapter. In the elaboration phase, the architecture of the system is designed, based on the detailed requirements analysis. There is a committed team for each stage of an iteration.

It therefore focuses on activities directly related to production of the software, for example, design, coding, and testing. These processes also affect the software development activity but are beyond the purview of software engineering.

And fi- nally, developing a prototype mitigates many risks that exist in a project where requirements are not well known. This is a complex task which can sngineering additional testing, conversion of old data for this software to work, training of personnel, etc.

The capability to provide failure-free service. Third, the quality of final software is likely to be far superior, as the experience engineers have obtained while developing the prototype will enable them to create a better design, write better code, jalotr do better testing. The use cases are generally numbered for ckncise purposes.

Consequently, the implementation of a development process model should ensure that each step in the development process produces information that the management process needs for that step. A use case can employ other use cases to perform some of its work. For each functional requirement, the required inputs, desired outputs, and processing requirements will have to be specified.

Some of these subgoals may be achieved by the concide itself, but they may also be treated as separate use cases executed by supporting actors, which may be another system.

However, as discussed earlier, it is not sufficient to just reach the final goal of having the desired software, but we want that the project be done at low cost and in low cycle time, and deliver high-quality software.

Frequently, during analysis, the analyst will have a series of meetings with the clients and end users. With a time box of three stages, the project proceeds as follows. And quality and productivity in the project will also depend critically on these decisions. We will focus on describing the behavior of software systems that are to be built. A software project is one instance of this problem, and the development process is what is used to achieve this purpose.
