OptimiZ Consulting is Kay Sever. I have never met her but I have exchanged many e-mails with her. I have read much of what she has written on the topic of improving quality in the mining industry. Now let me introduce you to her writings. Here are the papers she has sent me and which I have featured on TechnoMine and keep in the InfoMine library:
Her website tells us that an Operations Improvement Book is in progress. In the meantime, all I can recommend is reading her papers or better still call her at 480-545-9095 and get her out to your mine to put or keep you on the path to cost-effective quality work processes.
