This chapter deliberately merges four topics a Workday practitioner would otherwise meet as separate modules — IDE and metadata tooling, ALM and environment topology, performance and testing, and certification and career — because Workday collapses them into one tenant-and-community ecosystem. It closes with a concrete 90-day plan, a capstone checklist and an honest register of what is genuinely harder on the new platform.
This chapter is deliberately larger than the others, and deliberately merges four topics most technical readers would expect to find in three separate chapters: tooling and IDE, ALM and environment topology, performance and testing, and certification and career.
Everything you have configured in Workday lives behind a browser. Tenant configuration screens, Business Process definitions, Calculated Field expressions and EIB job definitions are all edited through the Workday UI;
A Workday programme moves configuration between tenants with the Object Transporter, which packages a set of configuration objects and imports them into the target tenant. D365 moves change through Azure DevOps version control (Git, in almost all current programmes), a build pipeline, and a deployable package — a signed artefact…
A typical D365 topology is Tier-1 (a full local or cloud-hosted developer VM, one per developer), Tier-2 (a shared sandbox used for integration testing, UAT or performance testing — a customer may have several), and Production. Refresh runs one direction only: from a higher, more production-like environment down to a lower one.
Workday's Financial Management reporting surface — standard delivered reports, Custom Reports, Worksheets, Discovery Boards and PRISM — is internally consistent because it all runs through the tenant's own infrastructure under one licensing and rate-limit model.
Workday's testing obligation is almost entirely manual: scripted regression walkthroughs, run against the Sandbox Preview tenant ahead of each named release, because there is no compiled artefact to test in isolation.
MB-500 (Microsoft Dynamics 365: Finance and Operations Apps Developer Associate) is the primary developer certification, and its current blueprint (verified against the official study guide) weights as follows: Plan the architecture and solution design 5-10%; Apply developer tools 5-10%; Design and develop AOT elements 15-20%;
By the end of the 90 days, one deployable package should demonstrate all of the following: a licensed Tier-1 environment; a Git-backed Azure DevOps project; an extension model referencing the base package; a table extension with at least one EDT-typed field; a CoC extension on validateWrite reproducing a real Business Process condition;
Being candid about what is genuinely harder matters more than a tidy transition narrative. None of the following are permanent — they resolve with practice — but pretending they are not real slows everyone down.
Workday collapses tooling, ALM, performance and career development into one tenant-and-community ecosystem; D365 spreads the same ground across Visual Studio, Azure DevOps, PPAC, and a wider certification landscape. None of the individual pieces are hard to learn in isolation — the volume is the adjustment.
