Planning your ISO 27001 journey

You've decided that ISO 27001 certification is valuable for your organization. This article gives you a concrete roadmap from start to certificate.

The journey in 6 phases

Phase 1: Preparation (Week 1-2)

Skills requirements

Must have:

  • Project management - Planning, coordinating, communicating
  • Organizational knowledge - Understanding processes, systems, stakeholders
  • Willingness to learn - ISO 27001 can be learned during the project

Nice to have:

  • Compliance experience - ISO 27001, GDPR, or other standards
  • IT security knowledge - Understanding technical measures
  • Audit experience - Knowing how auditors think

Tidal compensates:

  • ISO 27001 expertise - Built-in best practices
  • Control library - Predefined measures
  • Project templates - Proven implementation approach

Frequently asked planning questions

"Can we accelerate the journey?"

Yes, but not everything:

  • Acceleratable: Control implementation, documentation, team training
  • Not acceleratable: Internal audit (must come after implementation), management review cycle, external audit scheduling

Fastest realistic timeline: 10-12 weeks for small business with:

  • Dedicated project leader (part-time available)
  • Management directly available for decisions
  • Experience with compliance projects
  • Tidal expert support

"What if we need to change scope along the way?"

Within the project:

  • Small changes (adding/removing assets) usually possible
  • Large changes (new locations, business units) cost 2-4 weeks extra
  • Tidal flexibility makes scope adjustments technically simple

After certification:

  • Scope changes require extra audit days
  • Better to err on completeness during scope determination

"How do we know if we're on track?"

Tidal progress indicators:

  • Completion percentage per phase and overall
  • Risk coverage - percentage of risks with adequate controls
  • Document approval status
  • Team engagement - task progress

Key milestones checklist:

  • Week 2: Tidal in use and 'getting started' completed
  • Week 5: Risk assessment 100% complete
  • Week 8: All necessary controls implemented
  • Week 11: Internal audit without major findings
  • Week 13: Execution of management review

Ready to take the next step?

Most effective start:

  1. Set up Tidal account and invite team
  2. Plan stakeholder interviews for next week
  3. Block time in calendar for next 3 months
  4. Communicate project to organization
Tip

Project momentum: Start within 2 weeks of decision. The longer you wait, the more other priorities intervene.
