There is a famous process in continuous improvement called Plan-Do-Check-Act and it is a cycle that keeps repeating. It is a perpetual motion machine that just keeps going, there is no end. There other more sophisticated patterns as well, such as Shiba’s seven step method and each has its place. We prefer Shiba’s method when things are out of control and in the early stages of maturity. We like processes like Toyota’s when you are in control, in the top 10-15% of your domain and you are monitoring, keeping in control, and doing the fine tweaking and tuning.
You may be able to say that you have a great course or a great program, but you do not simply say it without proof. Even if things are perceived and 'proven' to be going well, the attitude is, 'this is fine, but we should look for ways to make things even better'. It is also possible to think that things are great when they are not (easy to be perceived the eagle in a flock of turkeys) or if you have no baseline. Arrogance and defensive attitudes can arise when there is no growth mindset, or the individuals feel insecure and are in over their heads. They will not want anything critically examined or questioned; things are just fine and we are going to keep doing what we are doing (I am ok, you are ok, I love you, you love me, I love me). They are taking it personal.
Quality movements come and go, the methods come and go, the methods get re-invented. There were major quality and waste elimination programs in the 1920’s. There were concurrent-engineering efforts, listening to the voice of the customer, just-in-time, etc. all before 1930. Unfortunately, processes such as these are soft processes and are subject to organizational memory, generations of management coming and going, and the same mistakes seem to arise from the ashes like a phoenix. If business is good, competition is low or the same, quality and improvement is often set aside. If there are business incentives, quality and ‘effectiveness and efficiency’ once again become movements and the thing to do.
Some cultures and business sectors have other drivers (historical, cultural, situational) that constantly drive a search for improvement and it is not only business drivers that inspire or move individuals and organizations.
In the end, it is the same game though: do not be satisfied with the present status quo, both the how and the what, think critically about it, do not take it personally, and take it up a notch. It is important to have reasonable and feasible goals for the end game and the next increment. Firms and organizations have failed dramatically when unrealistic goals have been set given the context (e.g., high quality usually comes at a price and you cannot deliver a cheap family sedan with the same quality materials, parts, and assembly care (fit and finish) as a luxury sedan. High quality processes take time to develop and are not 'free'; they definitely do not materialize through chanting and wishing. Bottomline, the goals must match the organization’s mission and objectives.
