Software Development Lifecycle PlanDesignImplementationTestingRelease
10
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
11
Design (R&D, CAE) Design the new function to meet the requirement. Ease of use. Functional specification
12
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
13
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 testing Automatic/regularPer project (R&D, QA, CAE, AC)
14
Release Documentation User Guide Reference Manual Release Note Training materials User feedback
15
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
16
You are developing a PRODUCT, not writing CODE.
