So what do they need to do?
The first step is of course to admit you have a problem and then you can assess your current state versus the best practices and understand your problem. Once you understand the gaps you can quantify the level of performance your organization needs to be successful, the work that it will take to get there, and the return on effort you will get for making the change.
Next you will need to create a reliability vision and develop the guiding principles the organization is going to use to change the way you do business. Communication and empowerment now come into play as you share with others the goals, the rules, and the boundaries so that they can then begin to attack the focus areas and gaps. This is not easy and it will be demanding on the organization as a whole as you battle to keep the focus and the drive to be successful but in the end the reward is worth the challenge and for many of these companies this challenge may be the only way that they can survive.
Does your organization have a reliability culture? For those that don't, what is it costing you? For those that have created this new culture what are you celebrating?
