The projects classified as Semi-Detached are comparatively less familiar and difficult to develop compared to the organic ones and require more experience and better guidance and creativity. Semi-detached – A software project is said to be a Semi-detached type if the vital characteristics such as team-size, experience, knowledge of the various programming environment lie in between that of organic and Embedded.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.These characteristics pertaining to different system types are mentioned below.īoehm’s definition of organic, semidetached, and embedded systems: All of these models can be applied to a variety of projects, whose characteristics determine the value of constant to be used in subsequent calculations. It is measured in the units of time such as weeks, months.ĭifferent models of Cocomo have been proposed to predict the cost estimation at different levels, based on the amount of accuracy and correctness required. Schedule: Simply means the amount of time required for the completion of the job, which is, of course, proportional to the effort put.Effort: Amount of labor that will be required to complete a task.The key parameters which define the quality of any software products, which are also an outcome of the Cocomo are primarily Effort & Schedule:
It was proposed by Barry Boehm in 1970 and is based on the study of 63 projects, which make it one of the best-documented models. It is a procedural cost estimate model for software projects and often used as a process of reliably predicting the various parameters associated with making a project such as size, effort, cost, time and quality. Cocomo (Constructive Cost Model) is a regression model based on LOC, i.e number of Lines of Code.
