Give importance to the "simple"
Steve Jobs offers inspiration: "That's been one of my mantras — focus and simplicity. Simple can be harder than complex: you have to work hard to get your thinking clean to make it simple. But it’s worth it in the end because once you get there, you can move mountains." BusinessWeek 1998
That says it all!
Establish "simplification rituals"
Simplifying is not natural => it's a decision to be promoted by concrete actions, since words alone do not suffice:
• Organize intra- or inter-team workshops, regularly, to diagnose what has become needlessly complex, time-consuming or even opaque, and experiment with new ways of doing things
• During individual review meetings, devote time to the process of simplification and saving time => What things, right now, take up too much of your time? Why? What is no longer necessary? What risks are there in doing less? etc...
• Establish a team dynamic around the idea of "let's simplify our work." This could be a system to share best practices on a collaborative wall, a contest :)...
Giving recognition to advances in simplification means first of all sharing, both within and outside the team.
It also means involving the company's directors in giving recognition: showing co-workers that they are esteemed for what they've accomplished in the areas of efficiency and transformation.
