Learn a repeatable framework for separating business pain, engineering constraints, documented facts, architecture choices, outcomes and teaching interpretations.
বাংলা অনুবাদ এখনো নেই, ইংরেজি দেখানো হচ্ছে।
Case studies become useful only when you can explain why a company changed its delivery system, not merely name the tools it adopted.

Use this framework for all ten case studies in the topic.
Every real-company case uses three labels:
A statement directly supported by the company's own engineering publication. Examples include a reported build time, deployment frequency, architecture component, or workflow.
A conclusion we draw from those facts. For example, if a company reduced project setup from days to minutes by standardizing pipelines, we may interpret that as a platform-engineering / cognitive-load improvement.
A contemporary implementation we might design today using tools already taught in bongoDev. It is a teaching adaptation, not a claim that the company uses those exact tools.
For each company, fill in:
| Question | Your answer |
|---|---|
| What was painful? | |
| What business/engineering constraint mattered? | |
| What was the bottleneck? | |
| What changed first? | |
| What became automated? | |
| What remained a human decision? | |
| How was blast radius controlled? | |
| How was success measured? | |
| What new complexity was introduced? | |
| What would you implement differently today? |
Do not draw only one architecture diagram. Draw three:
BEFORE → shows friction and handoffs
AFTER → shows delivery architecture
LOOP → shows metrics, gates, abort and recovery
By the end of this topic you should be able to receive a company scenario and produce:
Problem statement
Current-state value stream
Root causes
Target DORA-style metrics
CI architecture
CD architecture
Release strategy
Security controls
Observability / feedback
Rollback / recovery
Migration roadmap
Trade-offs
