So you are looking to improve your quality output, your productivity or improve your safety performance. I imagine your looking for consistent results right !.
So what do you need to do to improve your current performance and more importantly sustain that improvement?.
My advice do not make quick assumption and implement changes that relate to the symptom and not the true root cause. I like to use analogies so here is one on the subject.
Someone slips at work due to oil on the floor, the reaction to the symptoms would be to blame the house - keeping program and look at ways to step that up. Just hold on a moment and think about WHY and think WHY 5 times till you exhaust all the potentials and get to the true root cause.
Employee falls -WHY
Oil on floor - WHY
From material handling equipment - WHY
Leaking hydraulic seal - WHY
Equipment not serviced within guideline time frame - WHY
So from the original assumption its down to house- keeping, in fact the correct solution is to review the servicing program with the person or company responsible for the equipment.
You can apply the method to everything you do, as it's vital to get to the true cause of the problems before you can get to improving or removing them completely. In the long run it will save you time and money as it prevents you wasting resources on a symptom and not the cure.
So if your producing widgets, have production problems or errors just step back for a moment and ask WHY. You should be able to identify the cause of the issue , word of advice don't look to blame someone as it better to get the whole team adopting and using the method. If they feel it's a witch hunt they are likely to find the wrong WHY. (obviously if the real root cause is a breach of company policy or an illegal act then that's a different matter, in that case if you don't have an HR department then I would suggest bringing in a professional to help deal with it https://www.linkedin.com/in/tarnyabrink this is someone I would recommend you use).
So my challenge to you review some of the problem's you are experiencing and ask WHY, WHY,WHY,WHY,WHY... then solve it.
Let me know if you implement the 5 whys and what effect it had on the problem and solution.
