LEARN. PRACTICE. GROW.Concept and mechanism
Project cost does not end at implementation. Include parallel environments, support, observability, data, licenses, and decommissioning where applicable. A cloud forecast depends on assumed usage, configuration, and prices; the budget authorizes funding and does not automatically change with the forecast. Work with FinOps and budget owners to explain variances and options. In cost exercises, compare equivalent periods and scope without presenting fictional values as vendor prices. For obsolescence, identify product, version, dependencies, and support date confirmed in the applicable source. A date for another product does not establish your component status.
Guided application
In a fictional scenario, old servers appear idle for a week, but a quarterly consumer remains unconfirmed. Decommissioning needs validation of dependencies, data, and associated resources, with owners and evidence. Plan removal cost and effort within the project and confirm that expenses actually disappear. At closure, transfer remaining actions and track benefits with an owner and measurement date. If the objective was faster closing, measure the workflow before and after under comparable conditions; installing the solution is insufficient. The final report should preserve deviations, decisions, and lessons so later projects can reuse concrete knowledge.
Closing the project includes assigning later benefit measurement and remaining actions.
Common pitfalls
Forecast as approved budget; quiet week as no consumers; deployment as benefit.
