In this task you will review basic guidelines for startup day preparation.
DBA must be fully activated on a single startup day
DBA is an integrated MRP and shop control system that only works properly when all its processes – inventory, order entry, job and PO generation, purchasing, job release and processing, shipping, and invoicing – are fully functioning. It is therefore an absolute requirement that DBA gets activated on a single startup day.
A “rolling start” never works and leads to failure
A “rolling start” never works successfully and leads to failure. Whenever core elements are implemented one at a time, they never work properly. This leads to an inevitable cycle of fixes and workarounds which introduce data irregularities that often cannot be fixed or recovered from. The only way to get good results is to activate the entire DBA system on a single startup day as prescribed here.
Do not attempt to run processes in parallel
Once DBA is fully activated on system startup day, do not attempt to run processes in parallel in both accounting systems. This serves no purpose because MRP and shop control will produce entirely different results with no basis for comparison. Furthermore, running in parallel is technically not feasible because it will corrupt your financial accounting system with double-postings and conflicting data.
All pre-startup day tasks must be completed
Do not attempt to activate DBA until all pre-startup day tasks listed in this workbook are fully completed. In particular, make sure item MRP settings are fully specified because they drive job and PO generation. Also, make sure your work centers and routings are well defined because they drive shop control.
