or it can be applied at the software product component level for more accurate cost estimation in more detailed stages.The Intermediate Model can be applied across the entire software product for easily and rough cost estimation during the early stage.Intermediate Model: When Should You Use It

Intermediate Model: Cost Driver Categories The Intermediate Model estimates the software development effort by using fifteen cost driver variables besides the size variable used in Basic COCOMO.Average Staffing = 146 MM /14 months = 10 FSP.We estimate our project will have 32,000 Delivered Source Instructions.Using the formulas, we can estimate:.

We have determined our project fits the characteristics of Semi-Detached mode.

The Basic COCOMO estimates are within a factor of 1.3 only 29% of the time, and within a factor of 2 only 60% of the time.

Its accuracy is necessarily limited because of its lack of factors which have a significant influence on software costs.

Basic COCOMO is good for quick, early, rough order of magnitude estimates of software costs.

Basic COCOMO model estimates the software development effort using only a single predictor variable (size in DSI) and three software development modesД«asic COCOMO Model: When Should You Use It.

Assumes the requirements specification is not substantially changed after the plans and requirements phase.

COCOMO estimates assume that the project will enjoy good management by both the developer and the customer.

Primary cost driver is the number of Delivered Source Instructions (DSI) developed by the project.

COCOMO has three different models that reflect the complexity:.

COCOMO predicts the effort and schedule for a software product development based on inputs relating to the size of the software and a number of cost drivers that affect productivity.

It was developed by Barry Boehm in 1981.

COCOMO is one of the most widely used software estimation models in the world.
