Product metrics. Part 15. Agile and lean metrics

 

Agile & Lean Metrics

1. Velocity

Definition: The amount of work completed in a sprint, typically measured in story points.
Formula:
Velocity = Total Story Points Completed / Sprint

Examples:

  • SaaS Dev Team: 120 story points in a 2-week sprint
    → Velocity = 120
  • Mobile App Team: 90 points per sprint.
  • E-commerce Backend Team: 100 points/sprint average.

Use it to forecast future delivery timelines.

2. Sprint Burndown

Definition: Tracks remaining work (story points or tasks) over a sprint.
Use: Helps monitor if the team is on track to finish sprint backlog.

Examples:

  • Dashboard Team: Start: 100 points
    Midway: 50 points left → On track
  • Healthcare SaaS: Burndown flat → backlog not progressing
  • HR Tool Team: Rapid drop → over-delivering or under-estimating.

Ideal: A steady downward slope ending at zero.

3. Cycle Time

Definition: Time from work starting to completion.
Formula:
Cycle Time = Completed Date – Start Date

Examples:

  • CRM Feature: Started Mar 1, Completed Mar 4
    → Cycle time = 3 days
  • Bug Fix: 1 day
  • Report Automation: 7 days

Lower cycle time = faster iteration and value delivery.

4. Lead Time

Definition: Time from work requested to work completed.
Formula:
Lead Time = Completed Date – Request Date

Examples:

  • Customer-requested Feature: Feb 20 to Mar 4 →
    = 12 days
  • Internal Analytics Task: 5 days.
  • E-comm UI Update: 8 days.

Includes both wait time and actual development.

5. Work in Progress (WIP)

Definition: Number of tasks actively in progress at a time.

Examples:

  • DevOps Team: 4 WIP tickets during sprint.
  • Payments Team: 6 active user stories.
  • Design Team: 3 features in parallel.

Too much WIP can slow down delivery and reduce focus.

6. Cumulative Flow Diagram (CFD)

Definition: Visualizes work items in different states (e.g., to-do, in-progress, done).
Use: Tracks bottlenecks or excessive WIP.

Examples:

  • SaaS Backend: "In Progress" layer growing = bottleneck.
  • Design Team: Constant "Done" layer = smooth flow.
  • Healthcare App: Wide “Waiting for Review” = approval delay.

7. Escaped Defects

Definition: Bugs found in production after release.
Formula:
Escaped Defects = Post-release bugs / Total bugs

Examples:

  • Email Marketing Tool: 15 prod bugs / 100 total →
    = 15%
  • Online Tax Filing: 2 of 50 → 4%
  • Streaming Platform: 8/80 → 10%

Lower is better. High values indicate poor pre-release testing.

8. Team Happiness or Morale Score

Definition: A subjective score (1–10) or emoji scale of team health.
Examples:

  • Agile Dev Team: Avg. 8.2 happiness rating this sprint.
  • QA Team: 6.5 → burnout signs.
  • Product Team: 9.0 → high morale, good planning.

Beyond Google: The Best Alternative Search Engines for Academic and Scientific Research

Google may be the most popular search engine, but it isn’t always the best for academic and scientific research. Many valuable scholarly resources are buried under commercial results or hidden behind paywalls. Fortunately, there are specialized search engines designed to help researchers, students, and professionals find high-quality, peer-reviewed content. Here’s a selection of the best alternatives to Google, focusing on science, technology, medicine, and economics. 1. RefSeek ( www.refseek.com ) Best for: General academic research. RefSeek indexes over a billion documents, including research papers, encyclopedias, and books. Unlike Google, it prioritizes educational content and filters out commercial websites. 2. WorldCat ( www.worldcat.org ) Best for: Finding books and research materials in libraries worldwide. WorldCat allows users to search for books, articles, and historical archives in over 20,000 libraries. It’s ideal for tracking down rare or specialized academic ma...

LLM-based systems- Comparison of FFN Fusion with Other Approaches

  Comparison of FFN Fusion with Other Approaches & Suitable Use Cases FFN Fusion (NVIDIA) FFN Fusion optimizes transformers by identifying feed-forward layers that can be executed in parallel. By analyzing dependencies and fusing low-interaction FFN layers, it achieves significant reductions in inference latency and computational cost. Unlike traditional techniques that modify numerical precision or prune parameters, this approach restructures the model while preserving accuracy. Best Use Cases High-throughput AI applications : Ideal for AI assistants, chatbots, and large-scale LLM-based systems that need rapid multi-token generation. Enterprise-level LLM deployments : Works well where cost efficiency is important without compromising model performance. Real-time scientific research tools : Can enhance inference speed in AI-driven analytics, simulations, and predictive modeling. Quantization Quantization reduces the precision of numerical calculations (e.g., from 32-...
