Kaizen

Let go of assumptions.
Be proactive about solving problems.
Don't accept the status quo.
Let go of perfectionism and take an attitude of iterative, adaptive change.
Look for solutions as you find mistakes.
Create an environment in which everyone feels empowered to contribute.
Don't accept the obvious issue; instead, ask "why" five times to get to the root cause.
Cull information and opinions from multiple people.
Use creativity to find low-cost, small improvements.
Never stop improving.

Get employees involved. Seek the involvement of employees, including gathering their help in identifying issues and problems. Doing so creates buy-in for change. Often, this is organized as specific groups of individuals charged with gathering and relaying information from a wider group of employees.
Find problems. Using widespread feedback from all employees, gather a list of problems and potential opportunities. Create a shortlist if there are many issues.
Create a solution. Encourage employees to offer creative solutions, with all manner of ideas encouraged. Pick a winning solution or solutions from the ideas presented.
Test the solution. Implement the winning solution chosen above, with everyone participating in the rollout. Create pilot programs or take other small steps to test out the solution.
Analyze the results. At various intervals, check progress, with specific plans for who will be the point of contact and how best to keep ground-level workers engaged. Determine how successful the change has been.
Standardize. If results are positive, adopt the solution throughout the organization.
Repeat. These seven steps should be repeated on an ongoing basis, with new solutions tested where appropriate or new lists of problems tackled.
