estimation?

#### **What is COCOMO?**

The **Constructive Cost Model (COCOMO)** is a widely-used algorithmic software cost
estimation model that helps project managers predict the cost, effort, and schedule required
for a software development project. COCOMO was developed by **Barry W. Boehm** in
the early 1980s, and it provides a structured approach to estimate software project parameters
based on the size of the software being developed, measured in **Lines of Code (LOC)** or
**Function Points (FP)**, and various project attributes.

There are **three main levels of COCOMO** that offer progressively more detailed
estimations:

1. **COCOMO 81**: The original version of the model, which uses a set of basic equations
to estimate cost, effort, and time based on project size and other factors.
2. **COCOMO II**: An updated version of the model designed to handle modern software
development practices, including reuse, rapid prototyping, and object-oriented programming.
It offers more flexibility and better accuracy.
3. **COCOMO III**: A proposed extension of COCOMO II that aims to address emerging
software development trends, such as Agile methodologies.

#### **COCOMO Model Structure**

COCOMO uses a **set of equations** to estimate project effort and cost based on factors
such as the size of the project, complexity, and various environmental influences. The basic
structure involves calculating the **effort required** (usually in person-months) and
**schedule time** (in months).

### **COCOMO 81 (Basic Model)**

In its basic form, COCOMO uses the following equation for effort estimation:

\[
\text{Effort (E)} = a \times (\text{KLOC})^b
\]
Where:
- **E** = Effort (in person-months)
- **KLOC** = Estimated size of the software in thousands of lines of code
- **a** and **b** are constants derived from empirical data based on historical project data.
These constants depend on the project’s complexity and development environment.

- **a**: Varies between 2.4 to 3.6 depending on the type of project (organic, semi-detached,
or embedded).
- **b**: Varies between 1.05 to 1.20 depending on the project type.

#### **Project Types in COCOMO**

COCOMO classifies projects into three types, each with different values for **a** and
**b**:

1. **Organic Projects**: Small, simple software systems developed by small teams in

familiar environments. These projects typically involve a small number of developers and
low complexity.

2. **Semi-detached Projects**: Medium-sized software systems with a mixture of

complexity, moderate size, and more than one team. These projects require moderate
coordination and may involve different technologies.

3. **Embedded Projects**: Large and complex systems often developed in highly

constrained environments (e.g., embedded systems, hardware/software integration). These
projects tend to have stricter performance and reliability requirements.

#### **COCOMO II (Intermediate Model)**

COCOMO II builds upon COCOMO 81 but adds more detailed estimates and factors. It
includes:

1. **Early Design Model**: Provides initial estimates based on early-stage project

information.
2. **Post-Architecture Model**: Offers more refined estimates after the system architecture
has been decided.
3. **Reuse Model**: Accounts for the reuse of existing software components in the
development process.

In COCOMO II, factors like software reuse, the maturity of the software development
process, and the complexity of the software environment play a significant role in the cost
estimation.

#### **How is COCOMO used in project cost estimation?**

COCOMO is used for **predicting the effort (person-months)** required to complete a
software project, which can then be used to estimate project costs, timelines, and resource
allocation. Here's how it can be applied:

1. **Determine the Size of the Software**:

- Estimate the size of the software project in terms of **Lines of Code (LOC)** or
**Function Points (FP)**. This is usually done during the initial stages of planning or design.

2. **Select the Project Type**:

- Choose the appropriate category (organic, semi-detached, or embedded) that best
describes the project based on its size, complexity, and environment.

3. **Apply the COCOMO Formula**:

- Use the basic COCOMO formula (or the COCOMO II model for more detailed estimates)
to calculate the **effort** required in person-months. This is the number of developer
months needed to complete the project.

4. **Refine the Estimate with Cost Drivers**:

- COCOMO considers several **cost drivers** (e.g., product reliability, complexity,
developer experience) that can influence the effort required for the project. These cost drivers
are rated on a scale and then used to adjust the base estimate.

5. **Estimate Project Duration**:

- Once the effort is calculated, COCOMO uses a **schedule time** equation to predict
how long the project will take to complete. This is typically based on the effort and
complexity of the project.
6. **Calculate the Project Cost**:
- Multiply the effort (person-months) by the **average hourly or monthly rate** for the
developers to estimate the **project cost**.

#### **Example Calculation Using COCOMO 81**

Let's say a project is expected to have 50,000 lines of code (50 KLOC). Assume it is an
**organic project**. Using the formula for COCOMO 81:

\[
E = 2.4 \times (50)^{1.05} = 2.4 \times 60.24 = 144.58 \text{ person-months}
\]

If the average developer cost is $5,000 per person-month, the estimated cost would be:

\[
\text{Project Cost} = 144.58 \times 5000 = \$722,900
\]

#### **Limitations of COCOMO**

- **Accuracy**: COCOMO's predictions are based on historical data, so they may not
always be accurate for all types of projects, particularly those with novel technologies or
agile methodologies.
- **Size Estimation**: The model relies heavily on the size of the software (measured in
LOC), which can be difficult to estimate accurately at the beginning of a project.
- **Human and Environmental Factors**: While COCOMO accounts for some project-
specific factors (e.g., team expertise, complexity), it may not fully capture all organizational
and human factors that affect project success.

#### **Conclusion**
COCOMO is a powerful tool for estimating the effort, cost, and time required for software
development projects. It helps project managers make informed decisions about resource
allocation, timeline management, and overall project planning. However, it should be used
with caution and supplemented by experience, judgment, and other estimation techniques for
more accurate predictions.
