Knowledge Transfer & Growth
Uncaptured expertise is single-point risk. High performing engineering organizations deliberately convert individual experience into repeatable, discoverable, improvable assets. Effective knowledge transfer systems minimize onboarding time, reduce defect recurrence, and accelerate decision velocity.
Consistent hierarchical structure (area → asset type → version) enabling predictable discovery.
Automated stale detection (file age, dependency changes, open TODO markers).
Accountable steward per asset + rotating reviewer to avoid tunnel vision.
Time-to-learn, reuse ratio, update latency, orphaned asset count.
| Metric | Purpose | Collection | Healthy Signal |
|---|---|---|---|
| Onboarding ramp days | Speed to productivity | Automation + survey | < 14 days to 1st substantive PR |
| Playbook reuse count | Operational leverage | Scripted log scanning | Month-over-month upward trend |
| Stale asset ratio | Knowledge freshness | Modified date scan | < 10% > 120 days old (critical) |
| Shadow questions | Gaps in docs | Slack/issue tagging | Declining repetitive queries |
Scenario: Establish a sustainable, automated knowledge system that reduces onboarding friction and eliminates hidden tribal knowledge.

---
## Purpose
Safely revert a just-deployed hotfix causing instability.
## Preconditions
- Access to production deploy pipeline
- Latest commit hash of pre-hotfix state
## Procedure
1. Identify hotfix commit hash:
```
git log -1 --oneline main
```
2. Verify previous stable tag:
```
git describe --tags --abbrev=0
```
3. Revert:
```
git revert --no-edit
git push origin main
```
4. Trigger pipeline & watch metrics (link to dashboard).
## Verification
- Error rate returns to baseline
- Latency p95 within SLO window
## Rollback / Abort
If revert deploy fails → escalate to SRE on-call & freeze further deploys.

# ADR-010: Standardize Hotfix Rollback Procedure
Status: Accepted
Date: 2025-11-03
Context: Inconsistent rollback steps introduced variance & risk. Need unified, low-friction path.
Decision: Adopt single documented playbook + enforce link in incident template.
Consequences:
- Positive: Faster recovery, fewer mistakes, measurable adherence
- Negative: Requires maintenance when pipeline tooling changes
Follow-up: Add CI check ensuring playbook referenced in incident reports.

Ad-hoc “learn as you go” produces uneven skill growth, merge friction, and review drag. A structured tiered curriculum aligned to observable competencies enables predictable progression, targeted coaching, and measurable quality improvements in history hygiene and collaboration velocity.
| Tier | Focus | Core Modules | Assessment Signal | Promotion Criteria |
|---|---|---|---|---|
| Foundations | Core commands & mental models | Commits, staging, branching, diff | Correct branch + clean PR | Completes Foundations lab set |
| Operational | History rewriting & recovery | Rebase, squash, reflog, cherry-pick | Executes controlled history rewrite | Zero revision conflicts in review week |
| Advanced | Strategic collaboration patterns | Subtrees, submodules, bisect, hooks | Resolves multi-branch conflict elegantly | Leads conflict resolution walkthrough |
| Leadership | Standards & systemic improvement | ADR linkage, automation design, auditing | Drives a tooling enhancement PR | Authors accepted process ADR |
| Metric | Purpose | Collection | Healthy Signal |
|---|---|---|---|
| History Correction Incidents | Detect misuse of rewrite tools | Hook audit log | Downward trend post Operational tier |
| Conflict Resolution Time | Efficiency in merge complexity | Incident + PR timestamps | Median decreases after Advanced |
| Review Cycle Count | Quality of initial PR submission | PR metadata | ≤1.5 cycles avg after Foundations |
| Recovery Success Rate | Resiliency skill adoption | Lab assessment script | >95% successful exercises |
| Curriculum Coverage | Adoption breadth | Module completion registry | ≥80% team at Operational in 90 days |
Objective: Establish a structured, script-verifiable Git training curriculum with module templates, assessment automation, and progression tracking.

outcome: Perform a safe interactive rebase squashing noisy commits
assessment_script: scripts/assess-rebase.sh

## Concept Primer
Brief explanation of purpose & when to apply.
## Exercise Steps
1. Start from seeded repo state
2. Perform interactive rebase to squash commits 2–4
3. Preserve commit messages clarity
## Common Pitfalls
- Losing changes due to abort confusion
- Squashing already reviewed commits
## Reflection Prompt
What changed in your understanding of rewrite vs amend?

## Concept Primer
Feature isolation prevents unstable mainline changes.
## Exercise Steps
1. Create branch: `git switch -c feature/login-audit`
2. Make minimal change & commit
3. Push and open draft PR
## Pitfalls
- Inconsistent naming reducing searchability
## Reflection
How does naming impact collaboration?

Organic mentorship produces inconsistent growth and uneven knowledge distribution. A designed mentorship system accelerates capability compounding, increases retention, and reduces leadership bottlenecks by distributing coaching capacity.
| Model | Primary Purpose | Cadence | Strengths | Risks |
|---|---|---|---|---|
| 1:1 Mentor → Mentee | Focused skill acceleration | Weekly / Bi-weekly | Deep personalized growth | Scales poorly if not rotated |
| Peer Circles | Shared challenge processing | Bi-weekly | Collective learning & empathy | Can drift without facilitation |
| Guilds / Chapters | Domain excellence & standards | Monthly | Cross-team pattern alignment | Risk of ivory tower detachment |
| Rotation Shadowing | System exposure & perspective | Per rotation (2–4 weeks) | Fast context acquisition | Interrupts deep work if unmanaged |
| Expert Office Hours | Just-in-time unblock | Weekly / Ad-hoc | Reduces hidden queue of blockers | Can become support crutch |
| Metric | Purpose | Collection | Healthy Signal |
|---|---|---|---|
| Mentor Capacity Utilization | Balance load | Registry count | 70–85% utilization |
| Goal Completion Rate | Program effectiveness | Growth log aggregation | > 75% per cycle |
| Retention Delta | Impact on attrition | HR comparative | Lower attrition in mentored cohort |
| Feedback Quality Score | Mentor effectiveness | Post-session survey | Avg ≥ 4.2 / 5 |
| Skill Advancement Velocity | Acceleration of tier progression | Competency matrix diffs | Tier uplift within planned window |
Objective: Stand up a sustainable mentorship program with structured assets, tracking, and automated evaluation signals.
