When you need it
You have to choose between platforms, and every comparison you find was written by a vendor. The choice will shape cost, security and daily work for years, so the reasoning needs to be on paper.
What sets the quote
- Sized by the number of decisions and the options compared for each.
- One week: one decision with up to 3 options and 4 stakeholder interviews.
- Two weeks: one decision with up to 4 options and 6 interviews, plus a licensing comparison and a three-year cost estimate.
- Three weeks: up to 2 related decisions (for example workplace platform and identity) with up to 4 options each, 8 interviews, licensing and cost estimates.
- More decisions or options are quoted after the call.
What changes
- Your leadership gets a recommendation they can read in minutes and challenge in detail.
- The options are compared against your requirements, not against a vendor's feature list.
- The decision is recorded with its reasons, so it can be revisited when things change.
What you get
- Decision criteria agreed with your stakeholders
- Comparison of the options against those criteria, with a source for every claim
- Licensing comparison and three-year cost estimate for each option (in papers of two or three weeks)
- Security and identity implications of each option
- Adoption path and main risks for the recommended option
- Decision paper with a one-page summary for leadership and a clear recommendation
- A walkthrough with the people who will decide
Choose a decision paper when one platform choice is holding up other work; for a plan across several platforms, the cloud and digital roadmap fits better. We have written papers like these for Rayna Tours, including Microsoft 365 versus Google Workspace, Entra ID licensing and AI platform options.
Not included
- Implementing the chosen option (quoted separately, for example as identity modernisation or a landing zone sprint)
- Buying licences or negotiating with vendors
- Legal review of contracts or licence terms
- Proofs of concept (quoted separately if the decision needs one)
What we need from you
- A decision owner who agrees the criteria, and the stakeholders named in the quote for 45-minute interviews.
- Your current licence overview and the contracts that affect the decision.
- Read-only admin access where current settings matter, for example the Entra Global Reader role or a Google Workspace custom admin role with read-only privileges.
