Cost Estimation vs Back Of The Envelope Calculation

Developers should learn cost estimation to improve project planning, resource allocation, and stakeholder communication, especially in roles involving project management or leadership meets developers should use back of the envelope calculations during system design interviews, initial project planning, and performance optimization to quickly estimate metrics like latency, throughput, storage needs, or cost without detailed analysis. Here's our take.

Cost Estimation

Nice Pick

Developers should learn cost estimation to improve project planning, resource allocation, and stakeholder communication, especially in roles involving project management or leadership

• Related to: project-management, agile-methodologies

Cons

• Specific tradeoffs depend on your use case

Back Of The Envelope Calculation

Developers should use back of the envelope calculations during system design interviews, initial project planning, and performance optimization to quickly estimate metrics like latency, throughput, storage needs, or cost without detailed analysis

Pros

• It is crucial for identifying bottlenecks, setting realistic goals, and communicating technical trade-offs in a simplified manner, such as when designing distributed systems or evaluating database choices
• Related to: system-design, performance-analysis

Cons

• Specific tradeoffs depend on your use case
