Level of Effort (LOE)

This page documents the observed development timeline and a rough level-of-effort estimate for the MSN Weather Wrapper whitepaper work, based solely on git commit timestamps.

Summary

  • First commit: 711c94a6d7bc3c28827bbb4e5294cd9e058ef074 on 2025-12-02T15:42:52-05:00.
  • Last commit: f7a77a8666d0d0dded6dfd687e4feda764501a0e on 2025-12-05T18:18:52Z (13:18:52-05:00).
  • Wall-clock span: ~69 hours 36 minutes (~2.9 days).
  • Estimated active work time (first to last commit per day): ~36 hours.

Estimated Hours by Day

Date (local timezone in commits) First commit Last commit Approx. hours Notes
2025-12-02 15:42 23:51 ~8.1 Project kickoff; initial scaffolding and setup.
2025-12-03 12:07 20:28 ~8.4 Feature and documentation iterations.
2025-12-04 09:50 23:38 ~13.8 Heaviest day (features, docs, fixes).
2025-12-05 07:56 13:18 ~5.4 Final polish, merges, cleanup.
Total — — ~35.7 (~36) Sum of daily first/last windows.

Methodology and Assumptions

  • Source: git commit author timestamps (git log --format='%cI').
  • Hours per day are measured from the first to last commit that day; this captures time between first and last check-in, not continuous effort.
  • Actual hands-on time may be lower (breaks between commits) or higher (uncommitted work, reviews, local experiments).
  • Timezone shown per commit; some commits use -05:00, others UTC. Conversions were normalized when comparing spans.

Context

  • Work focused on the Modern Software Engineering whitepaper (docs/WHITEPAPER.md and artifacts/whitepaper.pdf).
  • The whitepaper outlines architecture, DevEx, testing, security, CI/CD, and recommendations for MSN Weather Wrapper.

How to Reproduce the Numbers

  1. Find the first and latest commit: git log --reverse --format='%H %cI' | head -n 1 and git log -1 --format='%H %cI'.
  2. List per-day timestamps: git log --format='%cI' and group by date.
  3. For each day, compute the span between the first and last commit; sum spans across days.

Caveats

  • LOE based on commit timestamps is a coarse proxy; use it only for high-level sizing.
  • Meetings, reviews, and uncommitted work are not reflected.
  • Multiple authors or timezones can skew interpretations.
