Success Rate Calculations and Widget Filtering Guide

Step-by-Step Explanation

1. Initial Setup

• Task Categories: Tasks are classified into categories based on their StatusType. Categories include:

  • Done
  • InProgress
  • DevelopingFeature
  • Deprecated
  • Research

• Purpose: Categorizing tasks by status type allows the code to separate completed (Done) tasks from others, which is necessary for calculating success rates.

2. Filtering Mechanism

Users can filter tasks by project and deliverable via dropdown menus. Here’s how filtering works:

• Project Filtering: When a project is selected, only deliverables associated with that project are shown.
• Deliverable Filtering: Selecting a deliverable displays only the tasks associated with that specific deliverable. The success rate is then calculated based on these tasks.

3. Success Rate Calculation

The success rate is recalculated every time the user selects a new deliverable:

1. Total Tasks: Counts all tasks related to the selected deliverable.

2. Completed Tasks: Counts tasks marked as "Done" for the selected deliverable.

3. Formula: The success rate is calculated using this formula:

   Success Rate = (Completed Tasks / Total Tasks) * 100

4. Non-Success Percentage: Calculated as 100 - Success Rate, this percentage represents tasks that are not yet complete.

4. Updating the Doughnut Chart

A doughnut chart provides a visual display of the success rate for the selected deliverable. The chart includes:

• Success Rate: The percentage of completed tasks.
• Not to Success: The percentage of tasks that are incomplete.

Each time the success rate is calculated, the doughnut chart updates dynamically to reflect the new values.

5. Workflow for Widget Filtering and Success Rate Visualization

To use this functionality:

1. Select a Project: This loads deliverables associated with the selected project.
2. Select a Deliverable: This filters tasks associated with that deliverable and recalculates the success rate.
3. View Success Rate: The doughnut chart updates to show the success and non-success percentages for the selected deliverable.
