The Pre-Job Brief and Post-Job Review
When we work, when we are at our best, we bring ourselves, our expertise, our creativity to what we do. We do excellent work, and the quality of our work depends upon not only WHAT we do, but also HOW we do it:
• HOWwecombineourskills,training,andinsight• HOWwecombinethemwithcollaboration,working relationships, and shared values• HOWwecombinebothourtechnicalresourcesand humantalents
Thiscombinationcomesinmanyshapesandsizes,butthemosteffectivewayistosimplydoourwork,wherenothingliesoutsideofourexcellentwork. So excellence in research and crafts, good working relationships, safe,secure,andenvironmentallyresponsibleworkareallsimplypartofour work — no add-ons, no extras, just good consistent work.

THE PRE-JOB BRIEFDEFINE WORK
The first step of the pre-job brief it is to define the work, asking key questions, such as…
What are the critical steps or phases of this work?
And…whatlessonslearnedcanwebringtothiswork,frompastpost-jobreviews?

So we’re safe in the building, it’s lightning protected, and we’re going to proceed withtheshotaswenormallywould.
Okay.

Once we’re in the firing sequence we’re going to follow this checklist step by step, and we’re not going to the next step unless the one before that stepischeckedoff.
