The TPI Next model defines 16 key areas, each covering a specific aspect of the test process, such as test strategy, metrics, test tools, and test environment. A process assessment leads to capability determination, which motivates process improvement. This may invoke a subsequent process assessment to measure the effect of the improvement.
The requirements for each level are defined in the form of checkpoints which are questions that need to be answered positively in order to qualify for that level. These checkpoints make an objective classification by maturity level possible. Improvement actions can be defined in terms of desired higher levels of test process maturity. Additionally, the model offers improvement suggestions to support test process improvement, which include a list of tips and ideas that can help in the effort to achieve the desired level.

Managing the testing phase is a skill that people acquire with years of experience. Every piece has to be aligned perfectly to carry out the testing process in full efficiency. Along with people’s skills, we also need support from individual testing processes as the execution of these elements decides other parameters as well. With no monitoring of increasing complexity, test management can become a cluttered arrangement of unorganized tasks. When such behavior starts to pop up, we may need to improve the testing process.
The same data often needs to be transformed from a separate source before it can flow into one or more systems. Therefore, rather than waiting for the execution phase of the test to begin, it is always a good practice to start by identifying the data sets as soon as the test design step is complete. We create negative and positive test cases when we develop test scenarios or cases. We need to test various data types using specific parameters and judgments to ensure the tests are carried out in the intended and desired way. Such models are popularly used to organize our testing process and define a set standard to be followed by all people, new and existing.
This will create a short-term burden of work, but will also ensure that your cycles are much faster. Of course, even “playing with the software for a bit and hitting release” is a process of sorts, and it would be more accurate to ask what level of process is appropriate for your business. The key to understanding whether your process is excessive is whether you feel the cons in the second categories start to outweigh the pros of the first. Process can also specifically target and avert the two negative outcomes listed there, by incorporating empowerment and speed in the letter of the process details.
Definition of objectives for improvement and their execution is customized according to the testing organizations needs and capacities. We work with software development teams of all shapes and sizes to improve what they do and efficiency of their work. Many of our clients are software teams that have robust test processes in place already, but reach a point where an objective assessment of how well they are working is necessary. It might be that their processes have become unworkable and too complex, or conversely, are no longer sophisticated enough to meet the needs of an increased testing workload.

Industry-standard models are helping to develop cross-organization metrics and measures that can be used for comparison. Several sets of recommended processes have materialized because of the need for process improvement in the testing industry. The staged models, such as TMMi and CMMI, provide standards for comparison across different companies and organizations. The continuous models, such as CTP, STEP, and TPI Next, allow an organization to address its highest priority issues with more freedom in the order of implementation. Properly used, these models can provide a degree of cross-organization metrics that can be used for benchmark comparisons.

This could include any training or mentoring required, piloting of processes, and ultimately, their full deployment. STEP is primarily a content reference model based on the idea that testing is a lifecycle activity that begins during requirements formulation and continues until the system’s retirement. Level four is achieved when the testing process can be effectively measured and managed at an organizational level to benefit specific projects.
A controlled maturity level includes the stakeholders to streamline the process with minimum structure. However, this just represents a controlled state of the process and in no way is optimized. Therefore, we can assume a lot of bugs will still exist if the organization is at maturity level 2. At maturity level 5, the organization has a series of methods set up for optimization of the processes followed in testing up to maturity level 4. With all the blueprints in our hand, we start the actual method of test process improvement. This should follow the guidelines and expectations described during the planning phase and focus only on defects pointed out during the diagnosis phase.
Thus, to stay ahead in a landscape that is quickly changing, adopting the Test Improvement Process becomes essential. We can help you identify the challenges faced by your testing team, how others in your industry are addressing these challenges and how to make the business case for change within your organisation. It also means that you can expect practical advice and actionable recommendations grounded in a deep understanding of software testing processes. This stage in continuous process improvement in software testing describes how to design and execute the tests that are included in the test plan. The test design typically includes test procedures and scripts, test cases, expected results, test logs, and more.
It enhances collaboration, enables faster iterations, and fosters a culture of continuous improvement. We analyze your software requirements, assess your QA maturity level, and provide a detailed action plan to achieve and maintain a game-changing QA process. There are many methods to enhance software testing and the testing process itself. They provide the guidelines for improvements as well as areas that need improvement.
We can witness it in development technologies, and even CI pipelines that get optimized with time. In such a case, if test process improvement remains stagnant and other processes improve with time, the quality of the application will suffer significantly. It is very important to align testing with other phases so that when other processes improve, we can strategize according to those changes as well. Sometimes referred to as TPI, test process improvement can be a continuous or non-continuous process depending on how the team operates. This involves depending on certain models that can help us reap the benefits of the end results. These benefits are important to discuss for further defining our motivation towards doing all this work.
In Systematic Test and Evaluation Process (STEP) and CTP it is not necessary for improvements to take place in a predefined sequence, unlike TPI Next and TMMi. On the other hand, if these tests are not done properly, even the most experienced and skilled teams can fail, making the most successful testers and Test Managers fail. Automated testing allows testing of the developed code (existing & new) rigorously and constantly.
- Expert Level provides in-depth, practically-oriented certification courses in a range of different testing subjects.
- The model offers insight into the “maturity” of the test processes within your organization.
- While an organization is certainly free to make its own rules in this regard, most of them rely on well-researched models that are efficient in discovering loopholes in the system.
- This, however, depends deeply on the project as a lot of things change when a new project is introduced.
Sometimes, the STEP assessment model is blended with the TPI Next maturity model. Learn objectives, tools, best practices, benefits, challenges, and future insights. Till today, the basic principles of improvement journey remain the same and with this post, we will try to take a peek into it using test process improvement. A Test Manager must pay attention to these activities to avoid the unwanted consequences.
