As a management analyst for 15 years who was charged with improving systems and eventually with running the TQM program, you will find that employees have plenty of ideas for changes that would help their jobs. What they don't have is trust in their managers.
They know they will get shot down, so they don't make suggestions or if forced to make suggestions will make only ones they think will be politically correct and of the most minor type to avoid rocking the boat.
Managers on the other hand are often threatened by employees making suggestions as they often see the need to improve the system as directly reflecting on their poor management of it. Managers often designed the existing system and thus have a stake in preventing others from pointing out its flaws.
If you do not confront this dynamic, any improvement program will fail. Managers must be rewarded for implementing employee suggestions. Managers must not be taken to task for having systems that need improvement (all systems need improvement!), they must not be called to explain to higher management why the system was broken to begin with.
Employees must learn that their suggestions will be taken seriously and that they will not be in trouble for making a suggestion. One way to do this is to "prime the pump" by getting a selected group of employees together to work on a particular thing that everybody has agreed is a problem and then implementing whatever they come up with whether the managers agree or not. Make sure the implementation is suitably advertised to the rest of the complany and that the people who made the suggestion get credit. But what is most important is that the suggestions be implemented without management having the chance to shoot them down.
Some suggestions will work and some will fail, just like the process changes managers make. But until you have a track history of implementing suggestions, you need to let the employees suggestions get implemented without shooting them down.
And make sure you have a budget for items related to making changes. This signals you are serious about it and it makes the larger, more important changes easier to implement. If you can save ten million dollars by spending 40 thouseand that's a win, but if there is no budget to get the 40 thousand to begin with, then the suggestion can't be implemented.
And personally, I'd never call a program Lean. To an employee this suggests that the real interest is in finding ways to get rid of employees.
