Why most TFP decisions get made without the full picture
IBM is steering customers toward Tailored Fit Pricing (TFP), but the migration mechanics, variant differences, and operating realities of TFP aren’t well documented in vendor-supplied material. Your IBM account team will explain how TFP works in principle. They don’t usually walk through which TFP variant fits your workload pattern, how to lower your baseline before you sign, or how to optimize within an existing TFP contract.
Whether you’re considering the move or already on TFP, the decisions you make in transition design, baseline calculation, and ongoing operation compound for the entire contract life. Most teams piece this knowledge together from IBM documentation, peer conversations, and trial and error — usually after the contract is signed.
This ebook is the document Zetaly’s customers kept asking for when they were navigating TFP, both pre- and post-transition. It is not a product brochure. It is the practical reference we wish every mainframe IT leader had on their desk.

Who wrote this — and why we have no horse in the race
Zetaly works with mainframe organizations across Europe and North America on cost optimization, capacity planning, and IBM contract preparation. We are not an IBM reseller. We do not earn commissions on which pricing model you choose. What works for one workload pattern does not work for another, and our recommendation depends entirely on what you are trying to optimize for.
This guide was built from real customer engagements: the questions that came up, the mistakes we saw, the trade-offs that mattered after the contract was signed. It is the document we now share with every new client at the start of a renewal-prep engagement.
Questions people ask before downloading
Is this really independent, or is Zetaly going to pitch me?
The ebook itself contains zero Zetaly product pitch. After download, you will receive one follow-up email asking if it was useful and offering a 30-minute conversation if you want to talk through your situation. If you don’t reply, you don’t hear from us again.
Does this cover Linux on Z, or only z/OS?
Tailored Fit Pricing applies to z/OS workloads. Linux on Z runs under different licensing terms and is mentioned only briefly. If your workload is mostly Linux on Z, the ebook is less relevant.
Does the ebook cover all TFP variants?
Yes. Part I.C covers the different TFP solutions (Software Consumption, Enterprise Consumption, Solution Consumption, etc.) with a comparison of their billing mechanics, baseline behavior, and operational implications. Picking the right variant for your workload pattern is one of the highest-leverage decisions in the transition.
We’re already on TFP. Is the ebook still useful?
Yes — Part III is dedicated to existing TFP customers. It covers staying within your contractual boundaries, producing more output within the same budget, and planning your next commitment. Many TFP customers leave significant value on the table because they treat the contract as static; Part III is about active management.
We’re considering TFP but renewal is 18 months out. Is it too early?
It is the ideal time. The strategies in Part II — particularly lowering your future TFP costs before the transition — take 6–12 months to implement properly. Starting 18 months out gives you the runway. Starting 60 days before signing usually means accepting whatever IBM proposes as the baseline.
Is there a French version?
Not yet. A French translation is planned. If you would like to be notified when it’s available, leave a note in the form.
