As a suggestion adopt a no blame investigative method analysis of your problems using a latent cause analysis or similar method eg
1. Gather all the lost time events evidence?
2. Keep the 3 P’s of evidence separate to avoid bias
2. invite all those identified as involved to a stakeholder meeting.
3. present the evidence to all involved.
4. Note: the only rule is you can’t blame anyone but yourself.
5. Let the evidence lead you to the truths of why things have failed.
6. People now have no where to hide and are not permitted to blame someone else. AS IT is EVIDENT who is at fault. THOSE responsible and accountable must own up and admit to thier failings before anything will change. ( note: several people are typically at fault)
7. When people change and corrective learning actions required are translated and sustained? you will start to succeed vs repeatedly fail and get casing safely effectively and efficiently to bottom trouble free.
