COCOMO Model Calculator
An essential tool for software engineers to estimate project costs using the COCOMO model, providing accurate and reliable calculations based on established metrics.
Results
Data Source and Methodology
All calculations are based on the COCOMO model as described in the original publication by Barry W. Boehm. For more details, refer to the publication: COCOMO on Wikipedia. All calculations strictly adhere to the formulas and data provided in this source.
The Formula Explained
Effort: E = a(KLOC)^b
Time: T = c(E)^d
People Required: P = E / T
Glossary of Variables
- KLOC: Thousands of Lines of Code.
- Effort (E): Person-Months required for the project.
- Time (T): Duration in months to complete the project.
- People Required (P): Number of personnel needed for the project.
How It Works: A Step-by-Step Example
Consider a project with 50 KLOC categorized as 'Organic'. The COCOMO model will calculate the effort, time, and personnel required based on the coefficients defined in the model for such projects.
Frequently Asked Questions (FAQ)
What is the COCOMO model?
The COCOMO model is a procedural software cost estimation model developed by Barry W. Boehm. It is used to estimate the cost, effort, and time to develop a software project.
What are the different types of projects in COCOMO?
The COCOMO model categorizes projects into three types: Organic, Semi-Detached, and Embedded, each with specific attributes and coefficients.
How do I decide the project type?
The project type is determined by factors such as the complexity of the project, team experience, and the environment. Refer to the COCOMO model guidelines for more details.
How accurate is the COCOMO model?
The COCOMO model provides a reliable estimate based on historical data and standard metrics, but actual outcomes may vary based on project specifics.
Can COCOMO be used for modern software projects?
Yes, COCOMO can be adapted for modern projects by adjusting its coefficients and recalibrating based on recent data.
