# Plex Production Scheduling Checklist > Source: https://netray.co/tools/plex-production-scheduling-checklist > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: Free Tools ## Short answer A grouped checklist covering master data, capacity, job readiness and daily routines for reliable scheduling in Plex. ## Category mes-shop-floor ## Erp Plex Smart Manufacturing ## Audience - Production scheduler - Plant manager - Plex administrator ## Tool **Kind:** checklist **Groups:** #### Master data **Items:** **Text:** Routings list operations in the real sequence used on the floor **Critical:** true **Text:** Cycle times and setup times reflect recent actuals, not original estimates **Critical:** true Every operation is assigned to the correct workcenter **Text:** Bills of material match current engineering revisions **Critical:** true Scrap or yield factors are set where history justifies them Alternate workcenters are defined where parts can run on more than one Inactive parts and routings are cleaned up #### Capacity and calendars **Items:** **Text:** Shift patterns and holidays are loaded for the planning horizon **Critical:** true **Text:** Workcenter capacity reflects available people, not only machines **Critical:** true Planned maintenance is scheduled so it blocks capacity Bottleneck workcenters are identified and reviewed weekly Overtime rules are agreed and documented Tooling or fixture constraints are captured where they limit scheduling #### Job and order readiness **Items:** **Text:** Jobs have due dates tied to customer or internal demand **Critical:** true **Text:** Priorities are agreed and visible to the floor **Critical:** true **Text:** Jobs are checked for material availability before release **Critical:** true Special instructions and drawings are attached Outside processing lead times are included Splits and partial quantities have a clear rule Rework and scrap replacement jobs follow a defined process #### Material and supply **Items:** **Text:** Shortage list is reviewed before the schedule is published **Critical:** true Purchase order dates match the schedule need dates Kitting or staging is timed to the start of each job Customer supplied material is tracked separately Lot and serial requirements are known before start #### Daily and weekly routine **Items:** **Text:** Schedule is reviewed with supervisors at the start of each shift **Critical:** true Late and at-risk jobs are reviewed every day Reported quantities and times are checked for completeness Unplanned downtime is logged with reasons Schedule changes follow a rule and are communicated Weekly review compares planned versus actual hours by workcenter Schedule adherence is measured and discussed **Scoring Note:** Count completed items against total. Resolve all critical items first: if any critical item is open, treat the schedule as unreliable until fixed. Items depend on your Plex configuration and modules; skip those that do not apply and note why. ## Content **Intro:** A schedule is only as good as the data and habits behind it. This checklist covers the master data, capacity, job readiness and daily routines that decide whether your Plex schedule matches what the floor can actually do. **Sections:** #### How to use the checklist **Body:** Walk through each group with the scheduler, a supervisor and a Plex administrator. Tick what is true today, not what is planned. Critical items are the ones that most often explain a schedule nobody trusts. Export the completed list to PDF, assign an owner to each open item and review it monthly. **Bullets:** - Tick only what is true today - Fix critical items first - Assign an owner and date to each gap - Repeat monthly or after major changes #### Why scheduling fails **Body:** Most scheduling problems trace back to optimistic cycle times, missing capacity constraints and jobs released without material. The software then produces a precise schedule built on inaccurate inputs. Floor teams learn to ignore it, and planners maintain a private spreadsheet. Fixing inputs is cheaper than any new tool. #### Measuring improvement **Body:** Choose a few measures and track them weekly: schedule adherence, on-time job completion, planned versus actual hours at the bottleneck, and the number of jobs released with shortages. If adherence is low, compare the routing times to actual reported times and update the biggest gaps first. Small corrections on high volume parts have outsized effect. #### Common mistakes **Body:** Teams often schedule to nameplate machine capacity and forget operators, setups and maintenance. Others release everything early to keep machines busy, creating work in process that hides priorities. Changing the schedule without telling the floor is another common failure. Agree rules for changes and publish them. **Cta:** If you want scheduling data from Plex and other systems queried in plain language with the query visible, Netray can discuss a private read-only setup. **Faq:** #### Does this checklist depend on a specific Plex module? **Answer:** It is written generally for scheduling in a Plex environment. Modules and screens differ by subscription and configuration, so skip items that do not apply and add items specific to your setup. #### How often should we review cycle times? **Answer:** At least quarterly for high volume parts, and whenever reported actuals diverge noticeably from routing times. Start with the parts that consume the most hours at your bottleneck. #### What is the first thing to fix? **Answer:** Usually routings and cycle times for the top parts by hours, followed by capacity calendars. Wrong inputs here make every other improvement less effective. #### Can I use it for other MES systems? **Answer:** Mostly yes. The groups of master data, capacity, readiness, material and routines apply to any finite or infinite capacity scheduling environment. ## Search terms Plex production scheduling, Plex scheduling checklist, Plex scheduler best practices, Plex job scheduling, Plex MES scheduling, production scheduling checklist manufacturing, Plex workcenter capacity, Plex daily scheduling routine --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
