Roll out ISO/IEC 27001 with gates that reflect how an ISMS actually matures.
This roadmap is built around decision quality and evidence quality, not arbitrary countdowns.

ISO 27001 implementations fail when they start at the wrong end. If you begin with a policy pack or a control checklist, you create an ISMS that looks busy but has weak traceability. The better pattern is phased: define scope and governance, run risk assessment, make treatment decisions, build the Statement of Applicability, implement the selected controls with evidence, and only then push hard on audit readiness and certification timing.
Your first milestone is a scope that can survive contact with the risk register, the Statement of Applicability, and the audit plan. This means documenting the ISMS boundary, relevant interested parties, dependencies on third parties, and the governance model that will own the system.
Do not leave scope decisions ambiguous because you intend to clean them up later. ISO 27001 scope drift is expensive once control evidence starts accumulating.
Next, define risk criteria, risk acceptance logic, and the assessment method that will produce consistent and comparable results. Then run the first scoped assessment. Keep the method simple enough that teams can actually reuse it when changes occur.
This phase should produce a clear baseline of material risks and decision points, not just a long list of issues.
This is the structural center of the roadmap. Select treatment options, determine necessary controls, compare against Annex A to confirm nothing necessary has been missed, create the Statement of Applicability, and build the risk treatment plan.
If the SoA and treatment plan are weak, every later phase is harder. This is where you want the most review discipline.
SSOT can take ISO 27001 Implementation roadmap from reusing this material inside a governed evidence system to a reusable workflow inside Sorena. Teams working on ISO 27001 can keep owners, evidence, and next steps aligned without copying this guide into separate documents.
Start from ISO 27001 Implementation roadmap and keep documents, evidence, and control records in one governed system.

Implement the controls that the ISMS needs, in the order the ISMS needs them. That usually means tackling controls linked to high-risk items, cross-cutting governance controls, and controls whose evidence takes time to accumulate.
Build implementation so it creates records naturally. Controls that work only when someone remembers to prepare evidence manually tend to fail under audit pressure.
Before certification planning becomes the main project, the ISMS should already have completed monitoring activity, internal audit, management review, and corrective action. That is the point where the system starts to look real to an auditor.
The goal is not to look mature for one audit window. The goal is to show that the ISMS has entered a durable operating rhythm.
