Many creative people who value their freedom might be discouraged from adopting a good decision making model based upon a five step process. Advocating x steps to anything immediately smacks of a process-driven, creativity-barren, bureaucratic black hole for individuality.
Quite the contrary.
Ben Goldacre is a doctor, academic and science writer who advocates evidence-based medical practice in particular, and who has extended the virtues of this approach to areas such as education. In a paper titled Building Evidence into Education Dr Goldacre said (my emphases):
'The opportunity to make informed decisions about what works best, using good quality evidence, represents a truer form of professional independence than any senior figure barking out their opinions. A coherent set of systems for evidence based practice listens to people on the front line, to find out where the uncertainties are, and decide which ideas are worth testing. Lastly, crucially, individual judgement isn’t undermined by evidence: if anything, informed judgement is back in the foreground, and hugely improved.’
Creativity, innovation, and professional freedom and the professional and personal learning and growth that follow are all products of a good decision-making process that relies on evidence rather than intuition or positional power.
