What is the Cocomo Model?
The Cocomo Model is a procedural cost estimate model for software projects and is often used as a process of reliably predicting the various parameters associated with making a project such as size, effort, cost, time, and quality. It was proposed by Barry Boehm in 1981 and is based on the study of 63 projects, which makes it one of the best-documented models.
The key parameters that define the quality of any software products, which are also an outcome of the Cocomo are primarily Effort and schedule:
- Effort: Amount of labor that will be required to complete a task. It is measured in person-months units.
- Schedule: This simply means the amount of time required for the completion of the job, which is, of course, proportional to the effort put in. It is measured in the units of time such as weeks, and months.
1. Organic
A software project is said to be an organic type if the team size required is adequately small, the problem is well understood and has been solved in the past and also the team members have a nominal experience regarding the problem.
2. Semi-detached
A software project is said to be a Semi-detached type if the vital characteristics such as team size, experience, and knowledge of the various programming environments lie in between organic and embedded. The projects classified as Semi-Detached are comparatively less familiar and difficult to develop compared to the organic ones and require more experience better guidance and creativity. Eg: Compilers or different Embedded Systems can be considered Semi-Detached types.
3. Embedded
A software project requiring the highest level of complexity, creativity, and experience requirement falls under this category. Such software requires a larger team size than the other two models and also the developers need to be sufficiently experienced and creative to develop such complex models.
COCOMO Model – Software Engineering
Cocomo (Constructive Cost Model) is a regression model based on LOC, i.e., the number of Lines of Code. This article focuses on discussing the Cocomo Model in detail.
