Jokela, Timo, Siponen, Mikko, Hirasawa, Naotake and Earthy, Jonathan (2006): A survey of usability capability maturity models: implications for practice and research. In Behaviour and Information Technology, 25 (3) pp. 263-282

“Improving the position and effectiveness of user-centred design (UCD) in software and product development is a challenge in many companies. One step towards improvements is to carry out a usability capability maturity (UCM) assessment to evaluate the strengths and weaknesses of a development organisation in UCD. While several diverse UCM models have been introduced, little research has been published in the public domain on these models. The paper aims to fill this gap by analysing the main features of the models. The results show that most models represent different approaches -- although some of them have the same roots -- meaning that understanding one model is not enough to understand the basics of another model. All models can be used for examining the status of UCD in individual development projects. In addition, models provide various means for assessment of the status of UCD in other organisational areas. The level of documentation of models varies a lot, and very few empirical research results exist. Based on the results, implications for practice and research are suggested.”

Earthy, Jonathan, Jones, Brian Sherwood and Bevan, Nigel (2001): The improvement of human-centred processes -- facing the challenge and reaping the benefit of ISO 13407. In International Journal of Human-Computer Studies, 55 (4) pp. 553-585

“Human-centred design processes for interactive systems are defined in ISO 13407 and the associated ISO TR 18529. The publication of these standards represents a maturing of the discipline of user-centred design. The systems development community see that (at last) Human Factors has processes which can be managed and integrated with existing project processes. This internationally agreed set of human-centred design processes provides a definition of the capability that an organization must possess in order to implement user-centred design effectively. It can also be used to assess the extent to which a particular development project employs user-centred design. As such, it presents a challenge to the Human Factors community, and indeed a definition of good practice may even be regarded by some as an unwelcome constraint. This paper presents the background to the process-level definition of user-centred design and describes how it relates to current practice. The challenges, benefits and use of a defined human-centred design process are presented. The implications for Human Factors and other disciplines are discussed. In Appendices A-D, the process terminology and the contents of ISO 13407 and ISO TR 18529 are described in more detail, and three examples are given (in Appendix D) of using this process improvement approach to improve the actual design methods in three organizations.”
