Measuring Success Using Metrics: The Second Key Metric – Productivity

This article is part 3 of our series on measuring success using metrics to assess the performance of augmented software teams. If you haven’t yet read part 1, we highly recommend starting there for an overview of the essential metrics for effectively managing software development projects, particularly in outsourced settings.

Managing productivity in software development teams, especially in an outsourcing context, is vital for delivering projects on time and maintaining high standards. Productivity metrics help teams track performance, identify areas for improvement, and ensure efficient project management. In this article, we will explore how to measure and enhance productivity with a focus on several key metrics.

Introduction

Productivity in software development refers to the efficiency and effectiveness with which a team accomplishes tasks and delivers valuable software. In outsourced projects where maintaining the budget is often important, high productivity is crucial for optimising resources, meeting deadlines, and delivering results that meet client expectations.

To understand and improve productivity, we will explore the following metrics: Team Member Satisfaction Rate, Velocity (Scrum), Feature Delivery Rate, Throughput (Kanban), Bug Fix Rate, Automated Test Pass Rate, Commit Frequency, Team Turnover Rate, Net Promoter Score, and Burn Down/Up Chart.

Detailed Metrics Analysis

1. Velocity

Velocity is a metric used in Agile (Scrum) methodologies. It measures the amount of work a team can complete in a single sprint, usually expressed in story points or hours. Velocity helps in predicting future capacity and setting realistic sprint goals.

How to Measure Velocity:

Sum Completed Story Points: Add up the story points of tasks fully completed in each sprint.

Calculate Average Across Sprints: Track velocity over multiple sprints to establish a stable average.

Exclude Partial Tasks: Only count tasks that meet the Definition of Done to ensure accuracy.

Adjust for Team Changes: Account for any changes in team size or experience, which may affect capacity.

Monitor Trends Over Time: Identify patterns or fluctuations in velocity to assess consistency.

Practical Advice:

Use for Forecasting, Not Target-Setting: Treat velocity as a planning tool. It can be used to indicate the team productivity, however it should not be used for target-setting.

Aim for Consistency: A stable velocity enables more predictable sprint planning and timeline forecasts.

Identify Blockers in Retrospectives: Discuss velocity fluctuations in retrospectives to find and address blockers.

Balance Complex and Simple Tasks: Evenly distribute complex tasks across sprints to maintain steady velocity.

Communicate Realistic Goals: Share velocity trends with stakeholders to align on achievable sprint outcomes.

2. Throughput

Throughput is used in Kanban and other flow-based Agile methodologies. It measures the number of tasks completed in each period, reflecting the team’s ability to move work through their process efficiently.

How to Measure Throughput:

Count Tasks Completed per Period: Track the number of tasks completed in each period (e.g., week or month).

Separate by Task Type: Track throughput for different types of tasks, such as features, bugs, or technical debt.

Visualise with Cumulative Flow Diagrams (CFDs): Use CFDs to visualise task flow and identify bottlenecks.

Track Long-Term Trends: Monitor throughput over time to detect improvements or declines.

Account for Task Size: If tasks vary in size, consider tracking throughput by story points instead of simple counts.

Practical Advice:

Identify Bottlenecks: Use throughput data to locate and address areas where work is consistently getting delayed.

Set Work-in-Progress (WIP) Limits: Limit the number of in-progress tasks to keep workflow manageable and efficient.

Prioritise High-Value Work: Focus on completing tasks that deliver the most value to ensure meaningful throughput.

Use Throughput to Plan Capacity: Historical throughput can help forecast the team’s capacity for future work.

Encourage Smooth Flow: Aim for a steady and consistent throughput to avoid peaks and troughs in productivity.

3. Bug Fix Rate

Bug Fix Rate measures the number of bugs resolved in each period. It reflects the team’s ability to maintain product quality by addressing issues quickly.

How to Measure Bug Fix Rate:

Count Fixed Bugs per Period: Track the number of bugs resolved in a specific period, such as a week or sprint.

Compare Against Reported Bugs: Measure resolved bugs relative to new bugs reported to assess backlog health.

Track by Severity: Separate bug fixes by severity level (e.g., critical, high, medium) to gauge prioritisation.

Monitor Backlog Size: Track how the bug backlog changes over time to understand the team’s handling of bugs.

Calculate Average Resolution Time: Track the average time it takes to resolve bugs from reporting to closure.

Practical Advice:

Prioritise Critical Issues: Focus on resolving high-severity bugs first to maintain system stability.

Balance Bugs and New Features: Allocate resources for both bug fixing and new development to avoid backlog growth.

Identify Recurring Issues: Identify and address the root causes of frequently occurring bugs to reduce future volume.

Review in Retrospectives: Discuss bug trends during retrospectives to find ways to improve quality.

Keep Stakeholders Updated: Regularly communicate bug status and trends to manage quality expectations.

4. Feature Delivery Rate

Feature Delivery Rate tracks the number of new features deployed over a period. It is crucial for understanding how quickly the team delivers new functionality, impacting customer satisfaction and competitive advantage.

How to Measure Feature Delivery Rate:

Count Features Delivered per Period: Track the number of features released in each period, (e.g. a month).

Differentiate by Feature Size: Account for the size and complexity of each feature to better understand productivity.

Measure Time-to-Market: Track how long it takes from feature conception to deployment to assess efficiency.

Segment by Feature Type: Separate by type (e.g., user-facing, backend) to analyse the balance of work.

Monitor Rework on Delivered Features: Track how often delivered features require adjustments or fixes post-launch.

Practical Advice:

Focus on High-Value Features: Prioritise features that deliver the most customer value or align with strategic goals.

Balance Quality and Speed: Avoid rushing features. Ensure quality standards are met to prevent rework.

Involve Stakeholders in Prioritisation: Engage stakeholders regularly to align feature development with business needs.

Set Realistic Delivery Goals: Use historical delivery data to set achievable goals for upcoming releases.

Celebrate Major Milestones: Recognise achievements in feature delivery to keep team morale high.

5. Automated Test Pass Rate

Automated Test Pass Rate reflects the percentage of automated tests that pass successfully. It indicates the health of the codebase and can correlate with higher productivity by catching issues early.

How to Measure Automated Test Pass Rate:

Calculate Pass Rate: Divide the number of passing automated tests by the total number of tests run (expressed as a percentage).

Track by Test Type: Separate pass rates by test types (e.g., unit, integration) for a detailed quality assessment.

Monitor Over Multiple Releases: Track the pass rate over time to detect stability trends and regressions.

Track Code Coverage: Measure code coverage alongside the test pass rate to understand the depth of test coverage.

Automate Test Execution: Use CI/CD pipelines to automatically run tests and gather results after each build.

Practical Advice:

Keep Tests Current: Update tests regularly to ensure they reflect the latest code changes and requirements.

Prioritise Critical Areas for Testing: Focus on automating tests for high-risk or critical parts of the codebase.

Address Test Failures Immediately: Investigate and fix failed tests promptly to maintain code quality. The Tester will need to do a follow up test on the failed test to confirm if the issue is actually a bug, or an error in the test automation script.

Balance with Manual Testing: Use automated tests for repetitive checks, while reserving manual testing for complex cases.

Use Trends to Monitor Stability: Watch for patterns in pass rates over time to assess the impact of code changes.

6. Commit Frequency

Commit Frequency measures how often developers commit code changes to the repository. It indicates developer activity but does not necessarily correlate with quality or value.

How to Measure Commit Frequency:

Track Commits per Developer: Count the number of commits made by each developer within a specific period.

Measure Average Commit Size: Track the size of each commit to ensure developers are making incremental changes.

Separate by Project Phase: Recognise that commit frequency may vary by project phase (like initial development or bug fixing).

Consider Task Complexity: Acknowledge that complex tasks may naturally result in fewer, larger commits.

Monitor Code Churn: Track how often committed code is later changed or removed to gauge stability.

Practical Advice:

Encourage Regular, Small Commits: Frequent commits help keep changes manageable and improve traceability.

Avoid Using Commit Frequency as a Performance Metric: Commit frequency does not necessarily reflect productivity, and must be used in context.

Analyse with Other Metrics: Use commit frequency alongside code quality metrics to get a fuller picture of productivity.

Balance Quantity with Quality: Frequent commits are beneficial but focus on meaningful changes over sheer volume.

Use Frequency Trends to Assess Workflow: Changes in commit frequency may indicate shifts in team workload or efficiency.

7. Team Turnover Rate

Team Turnover Rate measures how often team members leave and are replaced. High turnover can disrupt productivity and team cohesion.

How to Measure Team Turnover Rate:

Calculate Turnover Percentage: Divide the number of departures by the average team size over a specific period.

Track Reasons for Turnover: Distinguish between voluntary and involuntary turnover for better insights.

Benchmark Against Industry Standards: Compare your turnover rate with industry averages to identify any red flags.

Monitor Trends Over Time: Observe how turnover changes over time to catch patterns or spikes.

Assess Impact on Productivity: Track turnover’s impact on team capacity and project stability.

Practical Advice:

Create a Positive Work Environment: Foster team morale through recognition, fair policies, and growth opportunities.

Identify and Address Root Causes: Use exit interviews to understand reasons for turnover and make improvements.

Plan for Knowledge Transfer: Establish processes to transfer knowledge when a team member leaves to reduce disruptions.

Monitor for Early Warning Signs: Look out for signs of dissatisfaction (like declining engagement) to prevent turnover.

Encourage Team Cohesion: Run regular team-building activities to improve relationships and reduce turnover.

8. Net Promoter Score (NPS)

Net Promoter Score (NPS) gauges satisfaction and enthusiasm for the team’s performance from key stakeholders. It is a simple measure of how likely stakeholders are to recommend the team’s work.

How to Measure NPS:

Survey Stakeholders Regularly: Ask stakeholders to rate their likelihood of recommending the team’s work on a 0–10 scale.

Calculate NPS: Subtract the percentage of detractors (0–6) from the percentage of promoters (9–10) for the NPS score.

Track Over Time: Monitor changes in NPS over time to understand stakeholder satisfaction trends.

Segment Feedback by Stakeholder Type: Identify trends in feedback from different groups, like internal teams vs. clients.

Benchmark Against Previous Scores: Compare current NPS scores to past results to measure improvements or declines.

Practical Advice:

Follow Up with Detractors: Reach out to low scorers (0-6) to understand their concerns and work on specific improvements.

Identify Common Themes: Analyse feedback for recurring issues, then prioritise these for action to address the root causes of dissatisfaction.

Share Results with the Team: Communicate NPS scores and feedback to the team to foster transparency and motivate improvement.

Create an Action Plan: Develop a clear action plan based on feedback, and keep stakeholders informed on progress.

Celebrate and Engage Promoters: Thank high scorers (9-10) and consider them for referrals, testimonials, or case studies to boost team reputation.

9. Burn Down/Up Charts

Burn Down/Up Charts are visual tools for tracking project progress. Burn Down charts show remaining work over time, while Burn Up charts show completed work against the total scope.

How to Measure Burn Down/Up Charts:

Set Initial Scope: Define the total workload or project scope at the start of the sprint or project to establish a baseline.

Track Daily Progress: Update the chart daily with completed tasks to provide real-time visibility of project progress.

Add a Trend Line: Include an ideal progress line (trend line) to help visualise if the team is on track to meet the goal.

Record Remaining Work (Burn Down) or Cumulative Work (Burn Up): Burn Down Charts show work left, while Burn Up Charts show total completed work against the project scope.

Adjust for Scope Changes (in Burn Up Only): In Burn Up Charts, adjust the scope line if new tasks are added or removed, keeping stakeholders informed of scope creep.

Practical Advice:

Review in Stand-Ups: Use the charts in daily stand-ups to identify any blockers and ensure the team stays aligned with sprint goals.

Focus on Trends, Not Daily Fluctuations: Look at overall trends rather than daily ups and downs to get a realistic view of progress.

Analyse Chart in Retrospectives: Discuss the charts at the end of each sprint to understand what went well, and what needs improvement in future planning.

Use Burn Up for Long-Term Projects: For projects with changing scope, Burn Up Charts provide a clearer picture of cumulative progress.

Communicate with Stakeholders: Share the chart regularly with stakeholders to manage expectations and keep them updated on project status.

10. Team Member Satisfaction Rate

Team Member Satisfaction Rate measures how happy and satisfied team members are with their work and environment. High satisfaction often correlates with higher productivity and better outcomes.

How to Measure Team Member Satisfaction Rate:

Conduct Anonymous Surveys: Regularly survey team members about their satisfaction with aspects like workload, management, and growth opportunities.

Use a Consistent Rating Scale: Use a scale (e.g., 1–5 or 1–10) for survey questions to track changes over time.

Include Open-Ended Questions: Allow team members to provide detailed feedback on specific issues affecting their satisfaction.

Track Trends Over Time: Measure satisfaction at regular intervals (e.g., quarterly) to identify long-term trends.

Benchmark Against Industry Standards: Compare scores with industry averages (if available) to gauge how your team’s satisfaction ranks.

Practical Advice:

Act on Feedback Quickly: Address specific issues raised in surveys to show the team that their feedback is valued.

Promote Work-Life Balance: Encourage reasonable workloads and flexibility to prevent burnout and maintain satisfaction.

Recognise Achievements: Regularly acknowledge team members’ efforts and celebrate milestones to boost morale.

Encourage Open Communication: Foster a culture where team members feel comfortable discussing concerns openly with management.

Provide Growth Opportunities: Offer training, career development, and mentorship to keep team members engaged and satisfied.
