Bottom-Up Cost Estimating Exercise

Scenario:

You are a project manager tasked with developing a new software application. You need to create a bottom-up cost estimate for the project. The project is divided into four work packages:

1. Requirements Gathering & Analysis: This involves meeting with stakeholders to define the application's features and functionalities.
2. Design & Development: This includes creating the software architecture, coding the application, and testing the functionality.
3. Testing & Quality Assurance: This stage focuses on ensuring the application meets the defined requirements and performs as expected.
4. Deployment & Training: This includes deploying the application to the production environment and providing training to users.

Instructions:

1. Breakdown: Break down each work package into smaller, manageable tasks.
2. Cost Estimation: Estimate the cost of each task, considering labor, materials, and other expenses.
3. Cost Burdens: Apply appropriate cost burdens, such as overhead, profit margin, and contingency, to account for unforeseen expenses.
4. Aggregation: Calculate the total cost for each work package by summing up the costs of individual tasks.
5. Total Project Cost: Calculate the overall project cost by adding the costs of all work packages.
