During the Software Development Life Cycle (SDLC), each and every element and process of development is extremely significant. Knowledgeable experts carry out software designing, development and testing, while taking care of the minutest details. By doing so, the testers are able to ensure the quality and functionality of the deliverables is as requested by the client. One such element that carries a great deal of importance during the development process is Freeze. Divided in three categories– specification freeze, feature freeze and code freeze –Freeze is that point in the development process after which making changes in the source code and other related resources becomes stricter and difficult.
Freeze is executed at the end of an iteration or before the release of the product by reducing the scale or frequency of changes in the software. Moreover, modifications during this phase are ended completely after making sure that all the elements of the software are implemented correctly and do not consist any defects.
Code freeze is one type of Freeze, in which the code is frozen to prevent modifications done by developers. This mainly happens in the final stage of software development, as the code cannot be changed by developers once Code Freeze is implemented. Only in critical cases, where defects are found in the code after code freeze, developers change codes with the approval of organizations and change control board.
Any changes required to fix the critical defect is only done after getting this approval. Through this the developers are able to control defects and bugs in the system, which further secures the quality of the product. Post code freeze the software is deployed to production environment and is made perfect for release.
Though Code Freeze restricts modifications and changes in the software system, it provides developers several advantages. Developers all over the world use Code Freeze to reduce risks and to ensure that the system continues to operate without disruptions after its implementation. Some of the other reasons that make Code Freeze popular among developers are:
There are several reasons and advantages of using code freeze. However, it is important to look at the negative aspects of Code Freeze to get a better understanding of the same. This will enable developers to take important measures, which will further help them in avoiding problems in the latter stages of development of the software. Mentioned below are some of the disadvantages of using Code Freeze:
Before the initiation of Code Freeze, the team of developers and testers should keep these factors in mind and take precautions to avoid such scenarios. Moreover, they should be prepared for any hurdle that come in their way of initiating Code Freeze.
During Code Freeze the work of programmers and developers increases as it is usually implemented at the end of an iteration or before the release of the product. It is the responsibility of the programmers and developers to look for any discrepancies in the code source and other stages of the development process.
By performing this thorough analysis developers can prevent feature and functionality creep late into development process. Beside these, there are several other important things that are taken into consideration while implementing Code Freeze. These are:
The restrictions and constraints in Code Freeze can be unappealing to some developers, but by initiating it developers can enhance and secure the quality of an application. Moreover, it improves the features, functionality and specifications of the software, which further benefits the client’s organizations.
Developers and programmers pay extra attention to all the elements of the software before Code Freeze, as no changes or modifications are implemented in the source code or other related features once the code is frozen by the developers. Therefore, all the necessary changes and improvements are done during the Feature Freeze, where implementing changes is difficult and complex, but they are not restricted.
