① Guide · Vendor management
Most teams treat every mainframe renewal as a one off and spread effort evenly across vendors who do not deserve it evenly. A scorecard fixes that. Score each publisher on six dimensions, weight them to your priorities, and you know before the renewal calendar opens which vendor is the priority and why. Here is the framework, scored.
You cannot prioritize vendors you have never scored.
A mainframe estate carries software from IBM, Broadcom (CA), BMC, Rocket Software, Software AG, Compuware (BMC), and Syncsort (Precisely), and they are not equal. One vendor takes most of the spend. Another audits aggressively. A third has you locked in so deeply that a credible alternative does not exist. Yet most organizations walk into each renewal as if the vendors were interchangeable, spend the same effort on all of them, and discover the real leverage map only when the negotiation is already running.
A vendor scorecard replaces that guesswork with a repeatable ranking. You rate every publisher on a fixed set of dimensions, weight the dimensions to your priorities, and the result tells you where to put the negotiation effort and where you have none to gain. It survives staff turnover, it feeds the renewal calendar, and it gives sourcing a defensible reason to push one vendor hard and accept another quietly. This guide builds the scorecard dimension by dimension, with a worked scoring frame. For the disciplines behind it see renewal advisory and cost optimization.
Annual cost and the direction it is moving. A vendor whose spend is large and climbing is a priority regardless of how pleasant the relationship is. Score the absolute number and the multi year trend together; a small vendor rising fast can outrank a large one that is flat.
How rigid the agreement and its metric are. Capacity based metrics you can tune, caps you can hold, and exit rights you can use all raise the score. A take it or leave it consumption model with no caps lowers it. Flexibility is leverage you already own.
How the vendor behaves when the term ends or a review opens. Score the patterns you observe: aggressive uplifts, audit frequency, willingness to negotiate. A vendor with a hard renewal posture needs preparation that starts 18 months out, not a month before.
How real your alternative is. A product with a credible competitor and a manageable migration scores well, because the threat to leave is believable. Deep lock in scores badly, because the vendor knows you cannot move and prices accordingly. Be honest here; a bluff the vendor sees through is worthless.
Where the product and its owner are heading. Acquisitions, end of life signals, and consolidation pressure change the renewal entirely. A product that just changed hands carries risk that belongs on the score before the next renewal, not after it.
Whether you are getting the value you pay for. Poor support, slow fixes, and thin account engagement are negotiation ammunition and a reason to reassess. Quality belongs on the scorecard because it is the one dimension that justifies paying a premium, or refusing to.
| Dimension | Suggested weight | Score 1 means | Score 5 means |
|---|---|---|---|
| Spend and trajectory | 25% | Large and climbing fast | Small and flat or falling |
| Contract and metric flexibility | 20% | Rigid metric, no caps | Tunable metric, caps and exit rights |
| Audit and renewal posture | 20% | Aggressive, frequent, inflexible | Predictable, negotiable |
| Switching cost and lock in | 15% | Deep lock in, no alternative | Credible alternative, movable |
| Roadmap and ownership risk | 10% | Recent acquisition or end of life signal | Stable owner, clear roadmap |
| Support and delivery quality | 10% | Poor, slow, disengaged | Strong, responsive, accountable |
A lower weighted total flags the vendor that most needs attention this cycle. Weights are a starting frame; set them to your own priorities. The value is the consistency, not the decimal.
A structured way to rate each publisher in your estate against a fixed set of dimensions so comparisons are consistent year to year and effort goes where it is needed. It turns spend, audit behavior, lock in, and roadmap risk into a repeatable score that tells you which vendor is the priority and why.
Six hold up well: spend and trajectory, contract and metric flexibility, audit and renewal posture, switching cost and lock in, roadmap and ownership risk, and support quality. Each is scored on a simple scale and weighted to your priorities. The aim is a defensible, repeatable ranking, not precision to the decimal.
At least annually, and again whenever a vendor event changes the picture: an acquisition, a pricing model change, an audit notice, or a roadmap move on a product you depend on. The variables it tracks are exactly the ones vendors change, so treat it as a living input to the renewal calendar.
