Release

Planning (AC, CAE)

Understand the issue, and identify the root cause.

Users usually do not know what they want.

Requirement specification Input-Process-Output Acceptance criteria

Priority Schedule

Design (R&D, CAE)

Design the new function to meet the requirement.

Ease of use. Functional specification

Implementation (R&D)

Coding best practice Architecture/Design patterns Reuse De-coupling Coding style Code comment/documentation

Keep in mind Correctness always comes first. Efficiency (performance) Testability Ease-of-debug

Testing

Regression Daily Porting platform

Code quality Purify/Valgrind Purecov Quantify Coverity

Performance testing Runtime Memory

Unit test Module-level Command-level

Flow testing Alpha/Beta

Suggestions

Technical basics Algorithm, data structure, design pattern,

database, network Language is not the key. Master one or two

language is enough. Domain knowledge

Software is nothing but a tool. Team work vs one-man team

Communication ability is important. Prototyping vs completeness

You are developing a PRODUCT,

not writing CODE.
