Utrecht University: Software requirements from a ‘crowd’ of employees increases involvement and usefulness

CrowdRE is a recent paradigm that focuses on collecting requirements for software products by using input from a crowd. Data is collected in two ways: by explicitly asking feedback to a large number of users (a crowd), and by monitoring contextual and usage data of a product. Since feedback is directly gathered from a large group of users, rather than via a few stakeholders who act as proxies, CrowdRE gives requirements engineers a more trustworthy picture of the requirements of a product.

CrowdRE in governmental organizations
Wouters’ research project was the first to focus on a governmental organization: the Royal Netherlands Marechaussee, one of the four operational units of the Dutch Ministry of Defense. These organizations offer a unique context: they do not focus on profit and have to comply with several regulations that do not apply to private organizations, such as procurement laws. An organization-specific tool, called the “KMar Crowd”, was developed and used in two software development projects.

More than 520 employees actively contributed
Over a period of circa 3 months, more than 520 employees accessed the KMar Crowd and actively contributed to the development of the new software systems. 110 ideas were posted, 847 votes were cast, and the ideas were enriched with 106 comments. These numbers show that CrowdRE can successfully reach operational employees in governmental organizations, which is a difficult when using traditional RE techniques and are therefore less involved. Moreover, this is one of the largest CrowdRE studies so far.

By using the KMar Crowd, the requirement engineers could gain a unique perspective which is harder to obtain using more traditional techniques. Participants themselves indicated that they highly appreciated the way of working and would like to continue using the KMar Crowd. Over half of the posted ideas were sufficiently specific to implement in a minimal viable product, without additional work required for the requirement engineers.

The unique nature of governmental organizations required the researchers to adapt the CrowdRE method to fit the context at the KMar. For example, it was necessary to write summaries to keep the employees up-to-date without the necessity for them to read every idea. The researchers also found that the gamification element, used in previous CrowdRE studies to motivate participants, did not have an effect in this study, possible due to the specific nature of governmental organizations.
