Software Engineering: Causes of software maintenance problems

Software Engineering can be defined as the study (detailed study) of the engineering to the design, development, and maintenance of the respective software. And basically, the concept of software engineering is commonly introduced to address the issues related to low-quality software projects.

Besides, these problems are arises when the software development does not meet the following conditions that are as follows:

  1. Budgets.
  2. Quality issues.
  3. Timeliness.
  4. Budgets.

 

The main aim of software engineering is that they are meant to ensure that the software should be developed consistently with correctness within the time limit and under the budget defined for the particular project.

 

In this tutorial, we will learn about the following things as the part of software engineering is as follows:

 

  • What do you understand by the term Software Maintenance?
  • Process of software maintenance.
  • Need for software maintenance.
  • Causes related to the software maintenance problems.

 

 

What do you understand by the term Software Maintenance?

Software Maintenance is the process of performing a particular action such as changing, modifying and updating the software to meet the requirements of the clients or the customer interactively and creatively within the deadline. The maintenance of the software is implemented just after the product has been launched in the market for several reasons such as:

  1. Requirement of improvement in the software.
  2. To correct the errors and the bugs.
  3. We are making the necessary improvement so the developed software can remain competitive and relevant in the market.

 

The main objective or the purpose associated with software maintenance is to make modifications and the necessary updation in the software applications after their delivery to correct the errors and faults to improve the performance of the software which has been developed.

 

Categories of Software Maintenance

And the categories that are related to the maintenance of the software are as follows:

  • Corrective Maintenance: Corrective maintenance is essential for the maintenance of the software as they are used to find bugs and errors and rectify them as soon as possible when they are observed while the system is still in use and also used to enhance the system performance.
  • Adaptive maintenance: Adaptive maintenance is required when the customer wants the product to run smoothly on the new platform and operating system. For this, the updation and the modifications are made as part of the adaptive maintenance.
  • Perfective Maintenance: Perfective maintenance is applied when a software product requires maintenance to support the different new features for the other functionalities the user wants the product to achieve.
  • Preventive maintenance: Preventive maintenance involves the updation and modification to prevent the problems that can be raised in the future related to the software product.

 

 

Process of the Software Maintenance

There are the various processes that are associated with Software Maintenance are as follows:

  • Understanding of the program.
  • Generation of the particular maintenance problem.
  • Ripple effect.
  • Modified program testing.
  • Maintainability.

 

  1. Understanding of the program: The first and foremost step in the software maintenance process is understanding the problem, which involves making an accessible analysis of the respective program to get better insights or an experience of it.

 

  1. Generation of the particular maintenance problem: Generation of the particular concern is the second phase in the maintenance of the specific software. It consists of creating practical proposals related to the upkeep to accomplish the maintenance goals. 

 

  1. Ripple Effect: The third phase of software maintenance deals with accounting for the associated ripple effect as a consequence of the modifications in the programs.

 

  1. Modified testing: Modified testing is the fourth step in the maintenance of the software that consists of testing the respective modified program to ensure that the version of the applications has at least the level of reliability compared to the prior ones.

 

  1. Maintainability: Maintainability is the last phase in the maintenance of the software, and in these phases, all four stages defined above must be combined to form maintainability.

 

 

Need for the Software Maintenance

The different needs that are needed for the maintenance of the particular software are as follows:

  • Require for making better corrections to the incurred faults and the errors.
  • To make necessary changes in the design to improve its effectiveness.
  • They were needed to accommodate the programs so that various amounts of the software, hardware, features related to the system, and telecommunication-related facilities could be used.
  • To interface it with the other specific system.
  • It is needed for enhancements implementation. 
  • They are improving opportunities for changing the environment.
  • For obsolete remote functions.
  • Many more.

 

Causes related to the software maintenance problems

The different types of reasons that are associated with the maintenance of the software problems are as follows:

  • Lack of comments on the code.
  • Lack of traceability.
  • Obsolete Legacy system.
  1. Lack of comments on the code:
  1. The problem that arises during the maintenance of the software is due to the fewer comments written for the code used for the development of the particular software according to the requirement of the clients.

 

  1. Lack of the Traceability:
  1. It is a little bit difficult to trace the code required for the specific specification of the design of the respective software.
  2. To the programmer, it becomes challenging to detect the critical defect affecting the customer operations. If the detections are complex, correcting them won't be easy.
  3. Another problem is that the Life Cycle related documents will not be produced even to be part of the project's development.

 

  1. Obsolete Legacy System:
  1. The legacy system, which is the backbone of various industries such as the medical, telecommunication, transportation utility industries, and many other countries, is not designed well while maintaining maintenance.
  2. Moreover, it was assumed that they are not expected to last for more time (which means last for a quarter of a century or more).
  3. And the problem of traceability of the code associated with the software takes the maintainability of the software to the next level of difficulties.
