Rework Effort
Overview
Rework effort is a project management metric that indicates the additional time, resources, and effort required to fix or revise previously completed work that does not meet the required standards, specifications, or expectations.
Rework Effort Formula
This metric is calculated as the percentage of Effort expended on Rework activities in the software project to the overall total effort.
Rework activities can include various activities such as debugging code, revising documents, fixing bugs, or reworking designs to address feedback or improve quality.
Rework effort is calculated as follows:
Rework = Effort spent on fixing and retesting/re-reviewing
the software defects
Total Effort = Total effort spent on developing the software product
Rework Effort ( % ) =

Factors
Some factors that can contribute to rework effort in a software project are as follows:
- Changes in Requirements
- Bugs/Defects
- Lack of Skills
- Misunderstandings
- Tools
Changes in Requirements
Changes in project scope or requirements can necessitate adjustments to previously completed work, resulting in rework to accommodate these changes.
Feedback from stakeholders or clients may necessitate revisions to the work, requiring additional effort to incorporate the feedback and improve the deliverables.
Bugs / Defects
Mistakes, bugs, or defects discovered during testing or review processes often require rework to correct and ensure the desired level of quality.
Lack of Skills
If the team lacks the necessary skills or experience to complete the work correctly the first time, it may result in rework as they learn and improve.
Misunderstandings
If the requirements are not clearly understood or communicated, it can lead to deliverables that don’t meet expectations, requiring rework to align with the actual requirements.
Tools
Issues with tools, software, or technology used in the project can lead to errors or inefficiencies, requiring rework.
