Introduction to Evolutionary Process Models
An evolutionary process model is a model whose stages consist of expanding increments of an operational software product, with the direction of evolution being determined by operational experience. It combines elements of waterfall model and prototypes model. It develops the whole project as a number of stages, with the outcomes of one stages serving to identify the conceptual solutions for the next stage.
So the development proceeds in a series of implementations, each of which meets those requirements that are recognized and understood at the time of implementation. Each prototype is developed using a waterfall model to produce the prototypes.
The concept used in fig 2.10 is initially a basic implementation model. It is developed stepping through all the phases one by one to incorporate all the well understood requirements. This implementation is then shown and checked by the customer for its evolution. It is refined if feedback is given, so it goes through repeated stages until an adequate software has been developed. So the main idea is to develop a working model as quickly as possible which is then is carried out in a systematic manner.
The various phases of this model are:
1. Requirement Definition: is a step of thorough analysis used to create an initial requirements and specifications for the software.
2. Model Construction: is done having he phases design, coding and testing.
3. User Evaluation: is to check for its satisfaction and completion of work.
4. Iteration: is refining the model. If needed then any feedback can be given by the user that is implemented.
At last the end product is the working system.
Evolutionary models are often experimental in nature. Development starts with some small part of the system. For example, take a goods ordering system where ordering procedures for different kinds of goods. One way to start would be to develop a system for the subset of goods which are ordered in a straight forward manner. Once this is done and understood. We can go on to the next step of goods. Evolutionary based system is developed gradually. Te develops a system part and learns more about the problem from the operation of that part. The knowledge gained from this operation is sued to define the next part to be developed and the process continues. Each step adds a new capability to the system.
Uses of Evolutionary models
1. These models are used to develop the artificial intelligence systems which imitate human behaviours. It needs the use of very high level programming languages. This model been little used in software development other than in Al. This is because the management techniques that currently exist are not adequate to manage this model and the programs resulting from this tend not to be well structured.
2. Evolutionary model is now commonly used for developing business application using a fourth generation language (4DL) $GL are successful because there is a great deal of commonality across data processing applications. In essence many business applications are concerned with updating a database and producing reports from the information held in the data base
3. There are basically four types of evolutionary process models:
1. Incremental Model
2. Spiral Model
3. WINWIN Spiral Model
4. Concurrent Development model
