Phase 1: Discovery and Requirements Gathering (Weeks 1-4)

Every successful SAP Business One implementation starts with deeply understanding your manufacturing operations, pain points, and growth objectives.

Phase 2: Solution Design (Weeks 5-8)

With requirements documented, the Synesis team designs a solution that maps SAP Business One's capabilities to your specific manufacturing processes.

  • Bill of Materials structure: Define multi-level BOMs that accurately represent your production processes
  • Routing and work centers: Configure machine and labor capacity to support production scheduling
  • Costing method selection: Choose between standard cost, moving average, or FIFO based on your industry requirements
  • Warehouse layout: Map physical storage locations to SAP bin locations for accurate inventory tracking
  • Integration architecture: Design connections to MES systems, quality systems, and third-party applications

Critical Success Factor

Involve your best operators and line supervisors in the design phase. These are the people who understand the daily realities of your shop floor. Their input ensures the system works in practice, not just on paper.

Phase 3: Configuration and Development (Weeks 9-14)

This is where the technical team brings the design to life inside SAP Business One.

Data Migration

During this phase, the Synesis team configures all SAP Business One modules according to the solution design, develops any custom reports or add-ons, builds integration connectors, and performs iterative data migration test runs.

Phase 4: Testing and Validation (Weeks 15-18)

Rigorous testing is non-negotiable for a successful manufacturing ERP go-live.

Phase 5: Training and Change Management (Weeks 16-20)

Technology only delivers ROI when people use it effectively. A structured training program is essential for manufacturing environments where operators may have limited computer experience.

  • Role-based training: Customized curriculum for each user group — executives, managers, buyers, warehouse staff, production planners
  • Train-the-trainer: Develop internal SAP champions who can support ongoing learning
  • Hands-on practice: Provide a sandbox environment where users can practice without affecting live data
  • Quick reference guides: Create laminated step-by-step cards for common transactions

Phase 6: Go-Live and Stabilization (Weeks 21-24)

The go-live event itself should be anticlimactic — a sign that preparation was thorough. Plan your cutover for a period of lower production activity when possible.

Post Go-Live Support

Synesis provides dedicated on-site support during the first two weeks after go-live, followed by remote support during the stabilization period. Our goal is to ensure your team feels confident and productive with SAP Business One from day one.

Common Implementation Pitfalls to Avoid

  • Underestimating data cleansing: Dirty data is the number one cause of implementation delays — start early
  • Skipping change management: A perfectly configured system fails if users resist adoption
  • Over-customizing: Use standard SAP processes wherever possible to reduce upgrade complexity
  • Insufficient testing time: Never compress the testing phase to meet a deadline
  • No executive sponsor: Without visible leadership support, cross-departmental cooperation breaks down
