Case Tools in Software Engineering

Case Tools in Software Engineering

CASE(Computer-Aided Software Engineering) tools are a set of software applications that automates software development projects. Software project managers, analysts and software developers use CASE tools to develop software systems.

The primary idea behind CASE tools is that in-built programs can help to analyze developing systems in order to enhance quality and performance of the projects at every stage of the software development process, resulting in better outcomes. CASE tools in software engineering accelerate the SDLC process to produce desired results and uncover flaws before moving ahead with the next step in software development.

Throughout 1990, large corporations like IBM used CASE tools to assist in the software development process. Soon, these tools became part of the software lexicon and an advancement toward making software the mastermind of technology. 

There are various CASE tools available to simplify various stages of the SDLC process which include Analysis tools, Design tools, Requirement management tools, Testing tools, Database Management tools, Documentation tools and more.

Types of Case Tools

Requirements Management Tools

  • These tools help to collect user feedback, organize brainstorming sessions, create process flow diagrams and create a requirements traceability matrix.

  • Project managers can easily manage their product lifecycle with live tracking, reporting, real-time collaboration, versioning, test management and bug tracking features. This will support review meetings with stakeholders. 

  • Requirements management tools identify, manage, and capture changes in requirements and reuse them for various projects.

  • These tools provide freedom, framework, scalable procedures and integrations that aids in project flexibility.


  • Some widely-used requirement management tools with popular features are JIRA, Jama Software, SpiraTeam, Accompa and more.

Design Tools

Design tools help software designers to design the block structure of the software. The software can be further divided into smaller blocks using refined techniques. These tools provide in-depth information about each module as well as the relationships between them. Animated Software Design is an example of design tools.

Testing Tools

  • Testing tools or Quality Assurance tools help in monitoring the SDLC process and techniques to ensure the product is defect-free and quality is as per organization standards.

  • These tools can automate tedious tasks such as testing, checking, and verifying your software. 

  • Testing tools provide real-time feedback on your software quality and performance, to improve communication with team members, stakeholders, and clients.

  • Examples-JMeter, SoapTest, AppsWatch

Configuration Management Tools

These tools assist developers and project managers version management, revision control, automatic tracking and release management of the software projects. Whenever an instance of software is released, Configuration Management tools deal with –

  • Version and revision management
  • Baseline configuration management
  • Change control management

Fossil, Git, Accurev are some of the configuration management CASE tools.

Benefits of using Case Tools

  1. Improved productivity – CASE tools automates all processes involved in the software development process. This reduces the time taken in completing various tasks like design, coding, testing etc. specifically the tasks involving diagrammatic specifications. Thus CASE tools increase the system efficiency which results in improved speed and productivity of software development projects.

  2. Better collaboration among team members – With the use of CASE tools organizations eliminate communication gaps among required contributors to prioritize critical decisions. Real-time collaboration allows team members to upload documents, create pull requests and review codes of the project in a secure and centralized location.

  3. Reduced errors and defects – CASE tools offer techniques for error detection and removal. The tools detect error and remove it in the early stages of the development process. It plays a vital role as less cost, effort and time is consumed.

  4. Enhanced quality of software products – CASE tools provide an organized approach to the development process, enhancing the overall quality of the product. With better design, better analysis, automatic code generation, auto testing and debugging features, CASE tools ensure the development of high-quality products. Organizations gain a competitive advantage by marketing quality software products.


Challenges in using Case Tools

  1. High cost of acquisition and maintenance – CASE tools are associated with high acquisition cost and expensive maintenance. Small-scale industries engaged in small software development projects avoid the usage of CASE tools because CASE is beneficial only in the development of large systems.

  2. Steep learning curve – In most cases, during the initial phase of implementation programmers’ productivity may decline, as users need time to be familiar with the technology. Programmers are provided with training and on-site services to accelerate the learning curve and to the development and use of the CASE tools.

  3. Resistance to change from team members – Since using CASE tools requires adequate training to team members, resistance to change often arises from employees. They feel unprepared to adapt new processes due to a lack of onboarding, upskill training, and end-user support resources to walk them through the initial learning curve in a new process.


Best Practices for using Case Tools

  1. Conducting thorough research before selecting a tool – You need to conduct a thorough research and consider few things before selecting a tool-
    • Tools that match your specific needs, goals, and preferences.
    • Scope, scale, and complexity of your software project.
    • Tools compatible and integrate with your existing tools and systems.
    • Easy usability and accessibility of the tools for you and your team members.

  2. Providing adequate training to team members – CASE tools are associated with advanced features which require adequate training and ample time. Organizations need to create comprehensive employee training programs that give employees the knowledge and the necessary skills. Team members and employees must be provided with a thorough documentation on new processes, and trained in separate office hours.

  3. Regularly evaluating the effectiveness of the tool – Alongside, using CASE tools, you should also evaluate the effectiveness of the tools, like-
  • How well do your tools achieve the desired goals and results?
  • How well do they use the available resources and time?
  • How do they adhere to the standards and requirements of clients and the organization? 
  • What improvements can be implemented?


Conclusion

CASE tools in software engineering fliassist software program engineers at some stage in the SDLC procedure from necessities amassing and layout to coding, trying out, and protection. Design tools, Diagramming tools, Testing tools, Configuration management tools are some of the most broadly used CASE tools.


CASE tools can vary substantially in complexity and functionality, and their use depends on the specifics of the software development challenge. The proper equipment can dramatically improve the performance, collaboration, and best of software merchandise.


However, adopters face demanding situations inclusive of high costs and resistance to change. To get the maximum out of facts control gear, it’s essential to follow high-quality practices such as accomplishing thorough studies, providing appropriate training, and frequently testing the effectiveness of the tool.
