Step	Phase	What’s going on & why it matters
1-2	Requirement gathering	Stakeholder and IPS nail down specs so “nice-to-have” doesn’t sneak in as “must-have.”
3-6	Requisition & validation	The e-procurement platform enforces data completeness; IPS keeps bad or duplicate requests from entering the funnel.
7-9	Budget / policy approval	Automatic routing to budget holders and Finance prevents maverick spend.
10-14	Sourcing path chosen	If there’s a contract, IPS can order instantly; otherwise they run an RFQ/RFP and negotiate—big savings lever.
15-18	PO creation & order	A clean PO captures negotiated terms and locks pricing, delivery dates, and T&Cs.
19-21	Delivery & receipt	Stakeholder confirms they actually got what they asked for—critical for spend compliance on intangible services.
22-25	Invoice & payment	3-way match (PO, receipt, invoice) stops over-billing and errors; AP pays only when everything aligns.
26	Continuous improvement	IPS reviews spend, consolidates suppliers, and launches new sourcing waves to drive further savings and compliance.
