## What is COCOMO II?

Table of Contents

COCOMO-II is the revised version of the original Cocomo (Constructive Cost Model) and is developed at University of Southern California. It is the model that allows one to estimate the cost, effort and schedule when planning a new software development activity.

## Who proposed COCOMO 2?

Barry W. Boehm

The Constructive Cost Model (COCOMO) is a procedural software cost estimation model developed by Barry W. Boehm. The model parameters are derived from fitting a regression formula using data from historical projects (63 projects for COCOMO 81 and 163 projects for COCOMO II).

**What is COCOMO 1 and COCOMO 2 model?**

COCOMO I is useful in the waterfall models of the software development cycle. COCOMO II is useful in non-sequential, rapid development and reuse models of software. It provides estimates of effort and schedule. It provides estimates that represent one standard deviation around the most likely estimate.

**What are the weakness of Cocomo II model?**

The disadvantages of COCOMO include: ® It ignores requirements volatility (but an organization may add this as an extra adjustment factor in computing EAF). ® It ignores documentation and other requirements. ® It ignores customer attributes—skill, cooperation, knowledge, and responsiveness.

### How many stages are in COCOMO II?

three-stage

To summarize, COCOMO II provides the following three-stage series of models for estimation of Application Generator, System Integration, and Infrastructure software projects: 1. The earliest phases or spiral cycles will generally involve prototyping, using the Application Composition model capabilities.

### What are the weakness of COCOMO II model?

**Does COCOMO II replace traditional COCOMO?**

Does COCOMO II replace traditional COCOMO? You should use COCOMO II for most of your new projects. COCOMO 81 is still the best approach for some software projects.

**What are the strength of COCOMO 2 model?**

It works on historical data and provides more accurate details. Easy to implement with various factors. One can easily understand how it works. Easy to estimate the total cost of the project.
