1. To establish the project software scope and boundary conditions along with the acceptance criteria and operational concept, to determine what should or should not be known for developing the software product.
2. To determine the cost and schedule for the entire project.
3. To evaluate potential risks.
4. To verify one or more candidates' architecture against some primary sequence of events.
5. To separate the critical use cases and the primary scenarios of the system's operation.
Essential activities of the inception phase:
Developing the scope of the project:
1. It refers to the process of acquiring the requirements and operational concept in an information repository which is enough to determine the problem space and acceptance criteria for the final product.
2. Producing the architecture: It involves designing and evaluation of trade-offs, problem space uncertainties, and solution-space components.
3. An information repository is built, that determines the feasibility of one or more candidates' architecture in such a way that, the cost, schedule and resource estimates can be extracted.
Engineering and production stages:
1. In order to achieve economies of scale and to yield higher returns on investment, technological improvements in process automation and component-based development should drive the software manufacturing process and hence life cycle is categorized as follows,
Engineering Stage:
1. Engineering stages develop the plan, define the requirements, design the architecture of the software system by solving many development risks.
2. This stage comprises of a smaller team which is responsible for designing and performing composite activities.
3. Assessment of software system is carried out by demonstration, inspection, and analysis.
4. In the engineering stage, top-down project-independent planning guidelines are converted into project-specific planning guidelines.
5. So, that they can be used further as global assessment methods.
6.The software system and the two risk reduction factors
!.Schedule
!.Technical feasibility
7.Production stage: Production stage develop versions of capability within the plans, requirements, and architecture developed in an engineering stage.
8. This stage comprises of a larger team, which is responsible for testing, constructing and deploying activities.
9. Assessment of software system is carried out by employing different testing methods.
10. In the production stage, a bottom-up approach is preferred as it is necessary to have enough experience and exactness in the planning level.
11. In contrast to the engineering stage in the production stage, the final output product is the architecture baseline in the production stage the final output product is the production release baseline.
12. The only risk reduction factor used in this stage is cost.
