Our four-up charts are updated weekly and can be accessed at the following link: Four-Up Charts
Our team will continue to track time spent each week. Additionally, we will track two "project" metrics and two "process" metrics.
Effort Variance is the difference between the planned outlined effort and the effort required to actually undertake the task. Effort variance can show whether the team is successful at predicting required effort.
Effort variance = (Actual Effort – Planned Effort)/ Planned Effort x 100.
Productivity is a measure of the size of the software in relation to the effort spent in producing it. Software can be measured either in terms of lines of code or function points.
Project Productivity = Actual Project Size / Actual effort
Defect density is the number of defects detected in the software during development divided by the size of the software (typically in KLOC or FP). Defect density is a measure of the overall quality of the product. High defect density can indicate a process failure.
Defect density for a project = Total number of defects/ project size in KLOC or FP
Cost of Quality is the total effort spent on quality assurance activities: testing, reviews, procedures, etc. High cost of quality may indicate that the team is too focused on quality to be productive. However, a cost of quality that is too low could mean that the team is not spending time finding defects, which could also be an issue.
Cost of quality = (review + testing + verification review + verification testing + QA + configuration management + measurement + training + rework review + rework testing) / total effort x 100
