This is the 25th day of my participation in the November Gwen Challenge. Check out the event details: The last Gwen Challenge 2021
The next article continues with project establishment and survival models.
6. Predictive survival model
Predictive survival models include waterfall model and V model. Next, we will understand the characteristics of these two models
1. Waterfall model
(1) Project flow of waterfall model
The project flow of waterfall model is shown in the figure below:
(2) Project features suitable for waterfall model
The characteristics of projects suitable for waterfall model are as follows: requirements, schemes and similar projects. As shown below:
2. V Model
(1) Project flow of V model
The project flow of V model is shown in the figure below:
(2) Project features suitable for V model
For projects suitable for V model, the project features are as follows: requirements, schemes and similar projects. As shown below:
Iterative survival model
1. Iterative model — prototype
(1) The project process of the prototype model
The I project flow of the prototype iteration model is shown in the figure below:
(2) Project features suitable for the prototype model
For the prototype model of the project, there are two main characteristics, respectively: (1) the requirements are not clear; ② Hope to reduce the uncertainty of project demand. As shown below:
8. Incremental survival model
1. Incremental Model: Incremental Model
(1) Incremental model of the project process
The I project flow of the incremental model is shown in the figure below:
(2) Project features suitable for the prototype model
For the incremental model of the project, there are three main characteristics, respectively: (1) the requirements are basically clear, but may change; ② To grasp the market and users need to gradually understand; ③ System transformation needs to be implemented step by step. As shown below:
