151 | Type: workflow
Purpose: Illustrate the structured process for evaluating and selecting IT management graph technology, with decision gates at key points
Visual style: Swimlane flowchart with three lanes (left to right): Stakeholders, Evaluation Team, Vendors
Swimlane 1 - Stakeholders (left):
- IT Leadership
- Business stakeholders
- Budget holders
Swimlane 2 - Evaluation Team (center - main process flow):
- IT architects
- Data managers
- Operations leads
Swimlane 3 - Vendors (right):
- Vendor A
- Vendor B
- Vendor C
Process steps (flowing top to bottom in center lane):
1. Start: "Technology Selection Initiated"
Hover text: "Triggered by digital transformation initiative or legacy system pain"
Shape: Rounded rectangle
Color: Light blue
2. Process: "Define Requirements"
Hover text: "Document functional, non-functional, and organizational requirements"
Arrow from Stakeholders lane: "Input needs and constraints"
Shape: Rectangle
Color: Blue
3. Process: "Prioritize & Weight Requirements"
Hover text: "Categorize as Critical (must have), Important (strongly desired), or Beneficial (nice to have)"
Shape: Rectangle
Color: Blue
4. Decision Gate 1: "Build vs Buy?"
Hover text: "Initial decision: Custom build, vendor platform, or hybrid approach?"
Shape: Diamond
Color: Yellow
Three outgoing paths:
- "Build" path → goes to "Architect Custom Solution" (dotted line, exits workflow)
- "Buy" path → continues to step 5
- "Hybrid" path → continues to step 5 (evaluates vendors for core platform)
5. Process: "Issue RFI to Vendors"
Hover text: "Request for Information sent to potential vendors"
Arrow to Vendors lane: "Send requirements document"
Arrow from Vendors lane: "Receive vendor responses"
Shape: Rectangle
Color: Green
6. Process: "Initial Vendor Screening"
Hover text: "Eliminate vendors that don't meet critical requirements"
Shape: Rectangle
Color: Green
7. Decision Gate 2: "At Least 2 Qualified Vendors?"
Hover text: "Need minimum 2 vendors for competitive evaluation"
Shape: Diamond
Color: Yellow
Outgoing paths:
- "No" → loops back to "Revisit Requirements" (adjustment loop)
- "Yes" → continues to step 8
8. Process: "Conduct Proof of Concept"
Hover text: "Hands-on testing with real data and use cases (2-4 weeks per vendor)"
Arrow to Vendors lane: "Provide POC environment and support"
Shape: Rectangle
Color: Orange
9. Process: "Reference Checks"
Hover text: "Interview existing customers about their experience"
Arrow to Vendors lane: "Provide customer references"
Shape: Rectangle
Color: Orange
10. Process: "Calculate TCO & ROI"
Hover text: "Total cost of ownership and return on investment analysis"
Arrow from Stakeholders lane: "Provide budget constraints"
Shape: Rectangle
Color: Orange
11. Process: "Score & Rank Options"
Hover text: "Apply decision matrix with weighted requirements"
Shape: Rectangle
Color: Orange
12. Decision Gate 3: "Clear Winner?"
Hover text: "Is there a solution significantly better than alternatives?"
Shape: Diamond
Color: Yellow
Outgoing paths:
- "No" → "Conduct additional analysis" (mini-loop)
- "Yes" → continues to step 13
13. Process: "Prepare Recommendation"
Hover text: "Document findings, scores, rationale, and implementation plan"
Arrow to Stakeholders lane: "Present recommendation"
Shape: Rectangle
Color: Purple
14. Decision Gate 4: "Stakeholder Approval?"
Hover text: "Leadership approves recommendation and budget"
Shape: Diamond (in Stakeholders lane)
Color: Yellow
Outgoing paths:
- "No" → loops back to "Revisit Requirements" with feedback
- "Yes" → continues to step 15
15. Process: "Finalize Contract & Begin Implementation"
Hover text: "Negotiate terms, sign contract, kick off project"
Arrow to Vendors lane: "Execute contract"
Shape: Rectangle
Color: Dark green
16. End: "Technology Selected"
Hover text: "Selection complete, implementation begins"
Shape: Rounded rectangle
Color: Dark green
Adjustment loop (from Gate 2 "No" path):
- "Revisit Requirements" → either relax constraints or expand vendor search → returns to "Issue RFI to Vendors"
Timeline indicators (on right side of diagram):
- Steps 1-3: "Week 1-2"
- Steps 4-7: "Week 3-4"
- Steps 8-10: "Week 5-10" (POC phase is longest)
- Steps 11-14: "Week 11-12"
- Steps 15-16: "Week 13+"
Color coding:
- Blue: Requirements phase
- Yellow: Decision gates
- Green: Vendor engagement
- Orange: Evaluation phase
- Purple: Decision documentation
- Dark green: Completion
Visual elements:
- Dotted lines for information flow between lanes
- Solid lines for process flow
- Arrows indicate direction
- Loop-back arrows show iteration
- Gate symbols (diamonds) slightly larger than process boxes for emphasis
Layout dimensions: 1200px wide x 1600px tall
Implementation: HTML/CSS with SVG for shapes and connections, JavaScript for hover text display
