Prof. Neil Maiden is Professor of Systems Engineering at City University London. He is and has been a principal and co-investigator on numerous EPSRC- and EU-funded research projects. He has published over 150 peer-reviewed papers in academic journals, conferences and workshops proceedings. He was Program Chair for the 12th IEEE International Conference on Requirements Engineering in Kyoto in 2004, and was Editor of the IEEE Software’s Requirements column from 2005 until earlier this year. He can be reached out at N.A.
Requirements work is still regularly perceived as stenography, one in which the analyst listens and documents while the stakeholders tell the analyst what they want. This perception is reinforced by the requirements techniques that we use on most projects – the observations of work that we make, the interviews with stakeholders that we hold, and the questionnaires that we distribute to collect data about problems and requirements. These techniques hardly set the pulses racing. Nor do these techniques help us discover stakeholders’ real requirements.
Stakeholders don’t know what they want
One reason for this is that eliciting requirements relies on stakeholders knowing what they want and need. However, most stakeholders do not know what they want or need. They are limited by their perceptions of what is possible – what new business models can offer and new technologies can enable. Your average stakeholder is neither a business visionary nor a technology watcher. So is it surprising that their answers to your interview questions are so, well, banal?
Indeed, many businesses have come to realize that customers are more often rear-view mirrors rather than guides to the future. A new approach is needed – one that empowers your stakeholders. My advice? If you want to discover your stakeholders’ real requirements, encourage the stakeholders to create them.
Make them up.
Why not? After all, when you interview someone, the requirements that they report to you are the results of their own, often limited, creative thinking about a new system – creative thinking that you are capturing at the end of, too late to influence.
In this blog post, I argue it is more effective to get in earlier – for analysts to facilitate creative thinking about requirements as soon as requirements work starts. Think of requirements as the outcomes of creative work – desirable inventions that your stakeholders are guided to come up with. After all, many of your digital solutions should be giving you some form of business advantage, and establishing this advantage starts with requirements – what the solution will give to your business.
Creativity in Requirements Work
Perhaps to the surprise of many in software engineering, creativity is well understood. Many different definitions, models and theories of creativity are available, from domains ranging from social psychology to artificial intelligence. As a software engineer, I was delighted to discover how well the phenomenon has been studied. And how much software engineers could leverage from it.
I like the definition of creativity from Ster
Creative problem solving methods have been available since the 1950s. What is striking about many of these methods is their similarity to software development methods that emerged 25 years later. The CPS method guides people through activities such as problem finding, goal finding and solution acceptance – stages similar to analysis and testing phases of software development. What is different is the focus on creative thinking at each of these stages – creative thinking to maintain a critical advantage in business.

Another approach is to embed creative thinking into the early stages of agile projects – what we refer to as creativity on a shoestring because of the need to provoke creative thinking in less than an hour. We’ve learned to prioritise epics with more creative potential. We’ve identified creativity techniques that deliver new ideas in less than an hour – techniques such as hall of fame, creativity triggers and combining user stories.
Get More Creative
Much requirements work is creative. We need to adapt what we do to reflect this. Fortunately there are many creativity processes and techniques out there to experiment with. Do try – you will be rewarded.
