Today‚ the constant innovations in the software development industry are
testimony to the ever-increasing speed at which technology becomes obsolete. While more
companies continue to diversify and add IT to their portfolio‚ reduction in the cost of hardware is another factor that fuels the growth of software development. This has‚ in turn‚ led to increased pressure on software development organizations to lower their development and maintenance costs.
All this makes it imperative that software organizations follow sound practices not only during the development stage but also during the estimation stage. Incorrect estimates result in delays and customer dissatisfaction. The Constructive Cost Model (COCOMO) II is one of the most commonly used estimation model that allows one to estimate the cost‚ effort‚ and schedule for a software project. COCOMO II comprises of three models that estimators can use at different stages of the project depending on the amount of information available.
Effort and Schedule Estimation Using COCOMO II course includes:
- An Overview of COCOMO II
- Application Composition Model
- Early Design Model
- Post-Architecture Model
This course will enable you to:
- Explain the basic concepts of COCOMO II model.
- Understand how to use the Application Composition model for effort estimation.
- Understand the Early Design model and how to use it for effort and schedule estimation.
- Understand the Post-Architecture model and how to use it for effort and schedule estimation
You receive a certificate of completion after successfully completing this course.
After establishing the software lifecycle architecture‚ the actual development or maintenance of the software product starts. At this stage‚ the Post-Architecture model‚ the most detailed of the three estimation models‚ is used.
The Post-Architecture model uses KSLOC as the unit for size estimates. The Post-Architecture model uses 17 cost drivers‚ which can be categorized as follows:
- Product Factors: RELY‚ DATA‚ CPLX‚ RUSE‚ and DOCU
- Platform Factors: TIME‚ STOR‚ and PVOL
- Personnel Factors: ACAP‚ PCAP‚ AEXP‚ PEXP‚ LTEX‚ and PCON
- Project Factors: TOOL‚ SITE‚ and SCED
