Preface

Start with the software development cycle model , Simply analyze how to do a good job in process management
According to the goal and work efficiency focused at different stages of the product , Timely adjustment is a reasonable process management

One 、 The waterfall 、 iteration 、 Spiral model

The waterfall 、 iteration 、 The spiral actually evolved into a model , Take the waterfall as the starting point

1. The waterfall

• brief introduction ： The earliest model , Fixed process sequence from top to bottom , It establishes the basic activity content of software development , The biggest drawback is that it doesn't adapt to change , With the current software development environment , The waterfall model has little value .

6 A process ：
draw up a plan 、 Demand analysis 、 software design 、 Programming 、 software test 、 Operation and maintenance

2. iteration （RUP）

• brief introduction ： The process execution is still a waterfall model , But disassemble into each small product stage , Begin to approach the modern software development process

4 Stages ：
initial 、 elaboration 、 structure 、 deliver
9 A process ：
Business modeling 、 demand 、 Analysis and design 、 Realization 、 test 、 Deploy 、 Configuration and change management 、 project management 、 Environmental Science

3. screw

• brief introduction ： Combined waterfall 、 Iterative model , The process execution is still a waterfall model , Cycle by cycle , Take risk assessment as the core , Fast iteration is the goal , Every iteration , Product optimization once .
• The industry process can basically see the shadow of the spiral model .
• Advantages and disadvantages ：
  • advantage 1： At first it was very small , valuable / When the boss values , Then gradually expand the scale . Quick trial and error .
  • shortcoming 1： Testers intervene late , The defects buried in the early stage cannot be found and modified
  • shortcoming 2： Develop and test serial

Two 、V Model （RAD）

• brief introduction ： Rapid development model , At the beginning, there was a clear correspondence and subdivision between the test stage and the preliminary design , The testing process in the industry is the content of this model
• Advantages and disadvantages ： Although the testing process is refined , But for testers —— The advantages and disadvantages are similar to the spiral model

9 A process ：
Customer demand analysis 、 Software requirements analysis 、 Outline design 、 Detailed design 、 Software coding 、 unit testing 、 Integration testing 、 The system test 、 The acceptance test .

3、 ... and 、 double V（W） Model

• brief introduction ： be based on V The shortcomings of the model are optimized , Emphasize the parallel development, design and testing , It can be said that we should try our best to be close to the development parallelism , There's no way to solve it , The contradictory core of test management . Mainstream reference models in the industry .

Refer to the below ：

Four 、 summary

This article , It basically records the mainstream model of software development cycle , But how we use this knowledge in actual business is the key .
The process cannot be quantified , As a tester , In terms of management process, we still focus on product quality 、 Production efficiency is the fundamental consideration , Summarized below ：

Analyze from the following directions ：

• Product stage ： Trial and error 、 expand 、 Development 、 Stable
• Product size ： user 、 Maintenance cost 、 Personnel cost
• Mass efficiency balance ： Test management is an eternal topic , Constantly find directions for the boss to improve efficiency and quality

According to the above direction , combination V And spiral , Determine the appropriate process ：

• Fast ： Unclear product demand , Take each small prototype as the stage , The process reduces the outline design 、 Detailed design 、 Single measurement 、 Integration testing
• Balance ： Have a complete product demand target , Iteratively expand , The process is basically complete
• Stable ： Stable development and maintenance as the goal , Go to W The model is close to
