Tool-based Requirements Gathering in Agile
Requirements gathering is a vital process in software development life cycle. It becomes more challenging in an agile environment where the requirements are iteratively changing and new requirements are continuously coming in.
In an agile environment, it becomes easy to lose track of the requirements – you might miss some requirement in the implementation phase, you might overlook a requirement that was awaiting review or a decision, you might forget to cover some requirements in your testing process. As a test manager, you don’t want to encounter yourself with any of those situations. You desire agile requirement process to be efficient, effective and traceable.
How can you improve the requirements analysis and requirements gathering in agile environment? Have you thought of tool based requirements gathering in agile? If not, think now.
Tool based requirements gathering in agile will enable you to cope up with the rapidly changing environments. There are many requirements management tools available in the market.
These tools enable you to log your requirements and add details of your requirements. In any change of requirement occurs, edit history is maintained. You can not only see the conversations and decisions related to a requirement but you can also trace forward the entire activity, implementation and test cases created for the requirements.
In this article, we will discuss challenges of requirements gathering in agile environment. Then, we will discuss the benefits of tool based requirements gathering in agile environment. Finally, we will look various tools that helps you manage the requirements in agile.
Keep reading this article as it is going to cover various aspects of requirements gathering in agile methodology.
Challenges in Agile Requirements Gathering
Gathering business requirements and soliciting is a critical initial step in any project. If you succeed in creating a complete set of requirement up front, then you are able to create a thorough plan and accurate cost estimates which result in improved customer satisfaction and shorter delivery cycles.
During requirement gathering process it is a common pitfall that stakeholders disagree or underestimate development efforts and design. Some of the common challenges in requirements gathering process are discussed so that they can be addressed in a more potential manner:
Unclear success criteria
Stakeholders normally know about a problematic area or an opportunity that can be more explored but they don’t exactly know how to do or what to do about it. To address this issue, the best approach is to break a bigger project into smaller chunks and start working from the area about which client is clearer.
It is better to ask for samples or examples from client and ask them what exactly they like about those samples do you can easily identify their present business processes and weak areas.
Give them a high level model and get this done by a collaborative modelling tool so they can provide feedback earlier in the process and they have a better vision of the end product. It is good to make business requirements clear and quantifiable to have good results later on.
It is a common problem that stakeholders change their mind during the process or after the process. You need to be flexible to address this issue and allow the change to occur. It may occur due to unclear requirements or due to the evolution of the thought process.
Changes should be managed using estimation, prioritization and budget allocation. Establish a change control process in the SDLC. Changes should be communicated and approved before modifications are made.
Client does not want to speak up
An active client is a key to success in agile requirement gathering environment. For establishing trust, honest and open input is required. In some cases, client may not be comfortable in speaking up, so it is important to build a comfort zone with them and be ready to listen to them. Listening and being prepared to understand their problems may help to bridge the gaps.
When various groups are involved in development of a system, it is possible to have conflicts in priorities and views. When the issues are not resolved it is possible that individual agendas are promoted instead of following organization’s vision. The solution to this problem is that the project manager and all stakeholder sit together to discuss the conflicts, resolve them and make a definite decision on priorities.
Client insists on a particular technical solution
When clients have limited technical knowledge then this issue occurs. They may try to enforce a certain technology in their current project that was a success in a previous one. The best practice in this situation is to educate the client – make the client understand the differences in projects and support your argument with reasoning of why you are selecting a particular technology over another.
Benefits of Tool Based Requirements Gathering
Requirement gathering agile scrum environment is one of the tricky tasks to do. The first question that arises in minds is ‘How to collect requirements in agile?’. So the answer is by using best available requirements gathering software such as IBM Rational Door, ReQtest, Spiratest.
In agile environment several stakeholders contribute to requirement gathering process. Using a general purpose tool like excel is considered to be the basic approach in agile requirement gathering process.
On the contrary, you can improvise your agile requirement gathering process using a requirements management tool for this purpose is the best approach. There are various benefits of using a tool based requirement gathering approach:
Usually the problem that arises in agile projects is the undocumented, unstructured scope and requirements which can be a painful experience later on for the whole team. Getting your requirements in a proper structure is one of the key benefits of requirement gathering tools which means attributes can be defined and tracked for each requirement while making sure that they are being fulfilled.
Gathering requirements is a stressful thing to do. The cause of stress is the chaotic nature of this process. A good requirement management tool eliminates unnecessary stress which is associated with requirement gathering process by making things more manageable. With these kind of dedicated tools, it is possible to acquire feedback early and quickly. This avoids conflict that may occur later and become a problem for the whole team as well as the clients.
As they say ‘time is money’, in agile projects time is a key resource and every minute is important for the success of project and the team. A good tool that may help in saving a lot of time when it comes to management is always welcomed with open arms.
These management tools automate a lot of things such as creating change request documents, estimations, requirement documents – reducing effort and letting the team more focused on their designated tasks.
Best practices and workflow
The success of a product or project lies in well-defined workflows which helps in identifying responsibilities and tasks to each team member and in maintaining work balance throughout the team. These tools have built-in workflows and best practices for tasks related to requirements management. This helps in managing the team and results in a good result oriented approach.
Collaboration and communication plays a vital role in a team play. Lack of communication may result in unclear ideas and unsatisfactory result. As a solution, good tools are helpful in collaborating with internal and external stakeholders effectively and efficiently.
The comments and discussions are maintained under each requirement and can be tracked later on when the need comes. General-purpose tools are a failure in this regard as well as they lack in requirements related collaboration properties.
Top Software Requirements Gathering Tools/Software:
Now, let’s have a look at the list of requirements gathering tools that provide you requirements management solution.
