Code and Fix Model
Code and fix model
The first model of software development is not really a model but, the model is used in small projects. That model is the code and fix model. In code and fix model there are no required documentation, no quality assurance, no formal requirements or formal testing and delivery is haphazard at best. Do not even think about schedules and effort estimates when this model used. It tells take a minimal amount of time to understand the problem then start code.
Software development projects are complex. To deal with these complexities, many developers adhere to a core set of development principles. These principles define the field of software engineering.

First, a simple working system implementing only a few basic features is built and then that is delivered to the customer. Life cycle activities — Requirements of Software are first broken down into several modules that can be incrementally constructed and delivered. At any time, the plan is made just for the next increment and not for any kind of long term plans. Therefore, it is easier to modify the version as per the need of the customer. Development Team first undertakes to develop core features these do not need services from other features of the system. Once the core features are fully developed, then these are refined to increase levels of capabilities by adding new functions in Successive versions. Each incremental version is usually developed using an iterative waterfall model of development.
