Each parameter is broken down into a set of discrete states or dimensions, being qualitative or quantitative in nature. The scale of the problem is represented as a product of all the selected parameters and their individual states expressed as a total number of configurations. This is the problem space. Configurations where each state within a parameter is deemed consistent with every other state across the other parameters are identified and isolated. This is called the solution space. MA’s uptake has been patchy, and latterly overlooked mainly due to the user experience being compromised by three interrelated factors: poor access to support software which can address the combinatorial explosion generated by multi-parameter problem spaces inherent in the use of MA; insufficiently flexible processes that address users’ operational constraints; seen to be overly generic, disguising identification of specific application areas of interest. The main research aim in this thesis is to address these constraints. Action Research was used to develop a viable prototype, and beyond, making the product robust enough for commercially viability. The prototype combined algorithms and internal databases with cross-platform accessibility – an innovation complemented by improved processes to enhance user friendliness whilst maintaining methodological integrity. New research areas, including the latest incarnation of MA, are presented with particular emphasis in the areas of ideation, technological creativity and innovation. A company has been established to exploit the technology, with NATO purchasing a licence. With a paucity of in-depth literature on the method combined with little evidence of demonstrable outcomes the thesis is one of a handful of dedicated publications in the last 40 years thus providing a major contribution to the understanding of “Zwickian” Morphological Analysis. 4 PREFACE Acknowledgements The author would like to thank his supervisor, Professor Peter Childs, Head of the newly established Dyson School of Design Engineering at Imperial College. It was his initial enthusiasm for the topic of Morphological Analysis that enabled me to take up this research role, and by giving me his support and encouragement throughout the last three and a half years has led me to submitting this thesis. His interventions have been incisive and have kept me on the academic straight and narrow – a difficult ask when dealing with a student whose previous numerous decades had been spent in the business arena. I have also to thank my co-founder and director at Strategy Foresight Limited, Dr Nasir Hussain, a formidable “morphologist” in his own right, who has given me his profound support during this process. During our numerous discussions and work sessions, not just over the period of the PhD, but in the learning and experiential phase prior to starting the research programme, he has been instrumental in helping me to forge the ideas and concepts developed in this thesis. His understanding of the need for me to take time-out from conducting mainstream business at SFL has been of special value. Other acknowledgements of encouragement must also go to my other co-directors and colleagues at Strategy Foresight Ltd; Dr Giles Russell, without whom I probably would not have considered approaching Imperial College, Jeremy Glover, Dr David Campbell, Brenda King MBE and Dr Wes Harry. Mention of course must be made of the “in-house” team at the Dyson School, Sarah Wissing, Sam McKenny and Alex Marsh who have been ever helpful and cheerful. Thanks also to Gabriel Amorim and Erwin Saevedra who converted my instructions and product briefs into code. There is one acknowledgement that I have to make and this is to Dr Tom Ritchey, probably the leading MA practitioner and evangelist in recent times. It was Tom, whilst at the FOI in Sweden, who brought MA into the 21st century with the 5 development of the Carma/Casper software. Without his flying a lonely flag for MA these last couple of decades, my major re-engagement with MA, following earlier exposure to its value, might not have been re-ignited. Finally I have to mention naturally enough my wife, Golnaz, and my two sons, Sean & Patrick and my daughter Roaya. Apart from having to put up with me over these last three and a half years, none of them ever questioned why I should be doing a PhD at my age – their attitude being – “yes – go for it”. These last few weeks of writing up have been especially difficult (much more than just challenging), as I’ve had to battle against the twin evils of Procrastination and Formatting of text (when I was young we had secretaries to do that!). My wife and daughter have done sterling work in helping with the latter problem – the lack of an intuitive interface that MS Word and other Office features which I have confronted, has brought on severe bouts of “grumpiness” over the last few weeks for which I apologise.
