10 Myths About APS
When Advanced Planning & Scheduling (APS) systems emerged, numerous ERP proponents quickly dismissed this innovative technology without understanding its significance. Despite numerous success stories, some advisers and ERP merchandisers continue spreading myths in a futile attempt to impede progress.
This list, compiled by seasoned proponents of Finite Capacity Scheduling systems over the last twenty years, is grounded in numerous success stories and remains as valid as ever. The aim is to debunk misinformation that has circulated about scheduling. Most of these myths stem from individuals who fail to grasp the nature of the problem or its resolution.
MYTH 1: ERP SYSTEMS CAN HANDLE MY SCHEDULING PROBLEMS.
Unless your ERP system includes an APS system, this assertion is entirely wrong. Tackling scheduling issues using standard ERP/MRP methods is akin to solving a three-dimensional problem with two-dimensional tools. In essence, it cannot be efficiently accomplished.
MYTH 2: IF I BUY SCHEDULING SOFTWARE FROM MY ERP SELLER, I WON’T HAVE ANY DATA INTEGRATION PROBLEMS.
This assumption isn’t valid. Most ERP merchandisers lack the expertise needed to develop and implement their scheduling modules, leading them to purchase APS software companies. However, integrating APS into ERP systems often fails due to insufficient skill sets and mismatched approaches between the two systems.
MYTH 3: BECAUSE I HAVE SO MANY CHANGES, MY SCHEDULE IS GENERALLY OUT OF DATE BEFORE IT IS PUBLISHED.
This myth holds true if schedules are produced weekly. A good scheduling system can continuously reflect dynamic changes, providing real-time information crucial for making swift and informed decisions, setting you apart from competitors.
MYTH 4: MY SCHEDULERS RELY ON HOMEGROWN RESULTS USING EXCEL SPREADSHEETS BECAUSE OUR ERP SOFTWARE DOESN’T HELP THEM SCHEDULE.
While it seems reasonable, depending solely on Excel spreadsheets is impractical. Although Excel offers some control, the time-consuming nature of updating schedules offsets its benefits. Excel lacks features essential in a good scheduling system, such as visual scheduling and easy data integration.
MYTH 5: WE DON’T NEED A COMPUTER-GROUNDED SCHEDULING SYSTEM AS WE ARE ENFORCING SPARE GENERALITIES.
Replacing complex ERP systems with Kanban and demand-driven primer systems might seem appealing, but homemade systems lack the ability to plan around capacity constraints, becoming critical when removing time and force buffers.
MYTH 6: SCHEDULING SYSTEMS ARE TOO EXPENSIVE.
This myth holds true for inadequate scheduling systems. A good scheduling system can swiftly pay for itself and significantly boost profits. Neglecting this process might lead to selling capacity solely on a first-come, first-serve basis.
MYTH 7: I CAN DEVELOP MY OWN SCHEDULING SYSTEM.
While feasible for some, this task requires extensive knowledge of manufacturing and relevant software. Success depends on aligning software capabilities with business requirements, ensuring a well-coupled schedule with business processes.
MYTH 8: MY BUSINESS IS DIFFERENT THAN ANYONE ELSE’S.
Indeed, every business differs, but the core problems often remain the same. A good scheduling system adapts to your needs, eliminating the necessity of altering business practices to fit the system.
MYTH 9: WILL I ORPHAN MYSELF FROM NEWER SCHEDULING SOFTWARE PERFORMANCES WHEN MY REQUIREMENTS CHANGE AND I MAKE MAJOR VARIATIONS?
Unlike most ERP systems, modern scheduling systems allow customization without overhauling the core system. Upgrading to the latest version should be as simple as updating Excel, given the right APS system.
MYTH 10: I DON’T WANT TO KEEP DATA IN TWO SYSTEMS.
A good scheduling system should seamlessly integrate with your ERP system, shop floor data collection, and other relevant systems, eliminating concerns about managing data in multiple systems.
