Vendor Management

Covers the vendor lifecycle from selection to exit. Two failures dominate this discipline: tiering vendors by spend rather than by blast radius, and losing every point of renewal leverage to a missed notice deadline. This skill is built around preventing both.

When to use this skill

• Selecting a vendor and needing a scorecard that survives scrutiny
• A renewal is approaching and the notice deadline needs to be found before it passes
• Reviewing the vendor portfolio for concentration, risk tier coverage, and consolidation
• Preparing a business review with SLA performance and credits owed
• A vendor is underperforming and the case needs to be built on trend, not anecdote
• Planning an exit and needing the sequence right

Inputs the skill expects

• For selection: weighted criteria, must-have requirements, and 0-10 scores per vendor with evidence
• For the portfolio: annual spend, category, renewal date, notice days, and auto-renew flag per vendor
• Risk inputs per vendor: data classification, business criticality, alternative availability, subprocessor use
• Internal owner per contract
• For SLA reporting: committed metrics with target, actual, direction, credit tiers, and prior-period history
• Annual contract value and the contractual credit cap

Clarify First

Before generating, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Is the notice deadline known, or only the renewal date? — the notice deadline is what constrains action, and missing it removes all leverage for a full term
• Were the scoring weights set before any vendor was scored? — weights chosen after seeing candidates produce a justification, not a decision
• What does this vendor actually hold or touch? — data sensitivity and criticality drive the risk tier; spend does not
• Which must-haves are genuinely pass/fail? — every entry on that list eliminates a candidate, so preferences belong in the weighted criteria

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Workflows

Workflow 1 — Select a vendor

1. Agree weighted criteria and the must-have list before looking at any candidate. Record who agreed them and when.
2. Define anchors for each criterion — what a 10 looks like and what a 5 looks like. This is what stops the scorecard becoming post-hoc justification.
3. Score each candidate against evidence (demo, reference call, document reviewed), not impression. Note the evidence in the scorecard.
4. Run the scorer and read the stability check before the ranking. A margin under 5% is a tie — decide it on commercial terms, exit cost, or reference calls instead.
5. If the result flips when a weight moves 50%, take that criterion back to the decision owner before proceeding.

Workflow 2 — Review the portfolio

1. Build the vendor list with renewal date, notice days, and auto-renew flag. The notice deadline is derived, and it is the date that matters.
2. Set as_of explicitly so the analysis is reproducible and reviewable later.
3. Run the analyser and work the urgent renewals first — anything marked LOCKED has already lost its negotiating window for this term.
4. Check concentration in both forms: single-vendor share above 25-30% is a dependency, and category HHI tells you whether you have leverage or diversification.
5. Treat every unowned contract as a future auto-renewal. Assign an owner before anything else in the report.

Workflow 3 — Run an SLA review

1. Collect committed metrics with target, actual, direction, and credit tiers. Include prior periods — the trend is the argument.
2. Run the report and check credits earned against the contractual cap. Credits exceeding the cap mean the remedy structure is too weak to change behaviour.
3. Claim the credits. Unclaimed credits are the norm, and most contracts require you to ask.
4. Escalate severe breaches to the contract owner, not the account manager — the account manager cannot change the terms that caused it.
5. Carry the findings into the renewal ask: credit tiers that bite, and a termination right after repeated breach.

Decision frameworks

Risk tiering [PROVEN]

Score data sensitivity plus business criticality, then apply modifiers.

Data classification	Points		Business criticality	Points
PHI / health	4		Critical (revenue stops in hours)	4
PII	3		High (core function stops in a day)	3
Financial	3		Medium (productivity loss)	2
Confidential	2		Low (inconvenience)	1
Internal	1
Public	0

Modifiers: no ready alternative +2 · network access to your systems +2 · subprocessors +1 · non-adequate jurisdiction +1 · vendor under 20 people +1.

Total	Tier	Core obligations
8+	Tier 1 critical	Annual security review, quarterly business review, tested exit plan, SLA with credits
6-7	Tier 2 high	Full questionnaire at onboarding, semi-annual review, documented exit plan
4-5	Tier 3 moderate	Short-form questionnaire, annual review, verified data export
Under 4	Tier 4 low	Confirm what data it touches; nothing further

Tier by blast radius, not spend. The $8K tool holding your entire customer list outranks the $400K hosting contract holding nothing sensitive.

Where renewal leverage comes from [PROVEN]

Source	Worth	Requires
A real alternative	10-30%	3-6 weeks of genuine evaluation, an internal sponsor willing to switch
Vendor fiscal timing	10-25%	Knowing their year-end and aligning your close to it
Multi-year commitment	10-20%	Price protection, exit-on-SLA-failure, and an increase cap — all three
Volume / consolidation	15-30%	Real growth, not aspirational seat counts
Reference or case study	5-15%	Marketing time, not money
Annual prepay	5-10%	Cash-flow float, and a viability check first

Not leverage: complaining about price, threatening to leave without an alternative, escalating without a specific ask, or loyalty — long tenure lowers vendor risk, which is why tenured accounts are often priced higher.

Renewal calendar [PROVEN]

Days before renewal	Action
180	Usage vs entitlement; confirm owner; decide renew / renegotiate / exit
150	Open the alternative evaluation if renegotiating seriously
120	First vendor conversation — signal expectations before they build the quote
90	Notice deadline on most annual contracts. Serve notice if there is any doubt.
60	Negotiate substance: price, increase cap, true-down, SLA credits, exit rights
30	Close; anything open now resolves in the vendor's favour

Serving notice is not leaving — it converts an auto-renewal into a negotiation.

Terms worth more than price [RECOMMENDED]

Term	Target
Annual increase cap	CPI, or 3-5% maximum
Seat true-down rights	At renewal, without penalty
Termination for SLA failure	Defined breach threshold, no penalty
Data export format	Open, documented, and tested
Subprocessor change notice	30 days with an objection right
Assignment on acquisition	Consent required, or an exit right

Seat true-down is the most valuable and least-requested term: nearly every SaaS contract lets you add seats mid-term and forbids reducing them.

Anti-Patterns

Tiering by spend

Mistake: Applying diligence proportional to contract value — heavy scrutiny on the big infrastructure contract, a credit card and no questions for the $8,000 tool. Why it happens: Procurement owns the process and procurement thresholds are denominated in money. Approval workflows trigger on spend because that is what finance systems can see. Instead: Tier on data sensitivity and business criticality, with modifiers for substitutability and subprocessors. The small tool holding your customer list has a far larger blast radius than the large contract holding nothing sensitive, and it is exactly the one that gets bought on a card without a security review.

Discovering the notice deadline after it passes

Mistake: Tracking renewal dates only, then finding at day 60 that the 90-day notice window closed a month ago and the contract has auto-renewed for another year. Why it happens: Renewal dates are what contracts and calendars display. The notice deadline is a derived date nobody computes, and auto-renew clauses are written to be easy to miss. Instead: Track both dates per contract, and treat the notice deadline as the real one. Serve notice at the deadline as routine on anything you intend to renegotiate — it reopens the contract without committing you to leave. An unowned contract is the one this happens to, so assign an internal owner to every vendor.

The scorecard that ratifies a decision already made

Mistake: Choosing the vendor, then building a weighted scorecard whose weights and scores produce that vendor as the winner. Why it happens: Rarely cynical. Someone forms a view during the demos, and weights get set afterwards with that view in the room — each individual weight feels defensible while the set of them is not. Instead: Set and record the weights, with named anchors for what a 10 and a 5 look like, before any candidate is scored. Then run the sensitivity check: if the winner changes when one weight moves 50%, the result is an artifact of the weighting rather than a finding about the vendors, and the decision owner needs to see that before signing.

Treating the SLA as a control

Mistake: Accepting a 99.9% uptime commitment with a 2% service credit and considering the risk managed. Why it happens: The SLA exists, it has numbers in it, and it satisfies the checklist item. Nobody computes what the credit is actually worth against what an outage costs. Instead: Price the remedy. A 2% credit on a $20K quarter is $400 for an outage that may cost you far more — that is a rounding error the vendor has already priced in, not a control. Negotiate tiered credits (5/10/25%), a cap above 20% of period fees, and a termination right after repeated breach. Losing the account changes vendor behaviour; credits do not. And measure availability against the error budget, not the percentage — missing 99.9% by half a point is nearly six times the permitted downtime.
