I always like to go to Merriam-Webster first and see what they have to say on the matter. They provided the following tidbit of knowledge:
Definition of PLAN
This tidbit did not really clear up the matter for me so I then reached out to the Society for Maintenance and Reliability Professionals (SMRP) for the definition in their metrics compendium. In the glossary I found the following: "Planned work is work that has gone through a formal planning process to identify labor, materials, tools, and safety requirements."
Perfect! Now let's understand this word schedule. We will go back to Merriam-Webster for the definition:
Definition of SCHEDULE
transitive verb1: to appoint, assign, or designate for a fixed time2 a : to place in a schedule b : to make a schedule of
Now I believe we have all we need to wrap this up.So if you are talking about planned work, percentage planned work, planned job count or most any other maintenance metric with plan in the title then we are focusing on driving the completion of job packages which contain labor required, parts needed, tools needed and any permits, forms, drawings, or documentation.
If we see the metric "percent scheduled work" or any others that may have scheduled in the title then we are talking about time and how well we were able to stay on the time line for the week's work.
Later this week I will talk about the relationship between these two words in the maintenance and reliability world.
