Hello Karim and congrats on the new job!
I'll give you mine and my company's 5 cents.
1. Define the work process for work management (Daily/ weekly & Shutdown) & materials management (others if you have time RCFA, PM development, Essential care, engineering projects etc). Make sure you include TASKS in the workflow and WHAT ROLE is executing each task (Optionally responsible, Informed and Consulted as well).
2. Now you have the key tasks for each role and this will give you a core JOB DESCRIPTION for key roles
3. At this point, you can design an organization chart, because you know the responsibilities for each role.
Many will have an opinion on the BEST organization, but in my experience it is situational depending on how you, operations, and engineering decide to work together. For example, will planner do purchases or will purchasing? Will you have an inspector or will everyone inspect equipment? Who will be the central point to collect and do a suggested prioritization of all work requests? Will operators do essential equipment care? Who cleans equipment? Who schedules hourly craftspeople's work? When is the schedule posted? The list goes on and are done differently in plants.
Best Regards,
