IT rationalisation is often treated as a cost-cutting exercise. That is too narrow.
For a UK SME, the real objective is to create a technology estate that is secure, resilient, commercially justified and straightforward to manage. That means knowing which systems matter, what they cost, how they recover and who is accountable for them.
The following 90-day plan is designed for businesses preparing for growth, compliance activity, operational change or a major platform decision. It brings together ISO 27001 consultancy, Cyber Essentials readiness, Disaster Recovery, Microsoft Dynamics 365 Business Central, specialist IBM i Management and Technology Expense Management.
The sequence matters. Strategy first. Execution second. Otherwise, an organisation can spend three months purchasing tools that solve three different versions of the same problem.
The outcome at Day 90
By the end of the programme, a business should have:
- A complete inventory of systems, devices, applications, suppliers and licences
- A prioritised technology risk register
- A practical ISO 27001-aligned security improvement plan
- A Cyber Essentials readiness baseline
- Defined and tested recovery objectives for critical services
- A clear roadmap for Dynamics 365 Business Central
- A documented position for IBM i Management
- A rationalised view of software, connectivity and support expenditure
- A governance process to prevent technology sprawl returning
This is not a promise that every issue will be solved in 90 days. It is a promise of clarity, prioritisation and measurable progress.
Days 1–30: See the estate and stabilise immediate risk
The first month is about visibility. Decisions made without an accurate inventory are usually guesses wearing a spreadsheet.
Establish ownership and scope
Start by appointing a senior business owner for the programme. This may be a director, finance leader or operational executive, supported by an IT Consultant who can connect commercial priorities with technical decisions.
Define the scope of the review. It should normally include:
- Microsoft 365 and identity services
- Core finance and operational systems
- Cloud Solutions and hosted infrastructure
- Network Solutions and security appliances
- Voice and Connectivity services
- End-user devices and servers
- Critical suppliers and outsourced services
- Business applications and SaaS subscriptions
- IBM i Management arrangements, where applicable
For ISO 27001, this scope becomes the foundation of the information security management system. For Cyber Essentials, it helps establish which devices, users and services are within the certification boundary.
Build the technology and spend register
Create one central register containing:
- Hardware and operating systems
- Software and cloud applications
- Licence quantities and assigned users
- Contract owners and renewal dates
- Monthly and annual costs
- Support arrangements
- Business purpose
- Criticality and dependencies
Include seemingly minor items. A forgotten broadband circuit, dormant user account or unused software subscription may not appear significant individually, but together they create cost, security and governance problems.
This is the starting point for Technology Expense Management. The purpose is not to cancel services automatically. It is to understand whether each expense has a clear owner, business outcome and appropriate level of risk protection.
Identify the systems that stop the business
Work with department leaders to identify the services that would cause immediate disruption if unavailable.
These might include:
- Finance and enterprise resource planning
- Order processing and stock management
- Warehouse or logistics systems
- Email and identity services
- Customer-facing applications
- File storage and collaboration
- IBM i Management and associated business applications
- Network Solutions and Voice and Connectivity
For each critical service, record the current backup method, recovery owner and supplier contact. Then define provisional:
- Recovery Time Objective (RTO): how quickly the service must be restored
- Recovery Point Objective (RPO): how much data loss the business can tolerate
“Restore it quickly” is not a recovery objective. It is an aspiration.
Close urgent Cyber Essentials gaps
The NCSC describes Cyber Essentials as a baseline against common online threats, built around five technical controls: firewalls, secure configuration, security update management, user access control and malware protection.
During the first 30 days, prioritise the basics:
- Enforce multi-factor authentication for administrative and remote access
- Remove dormant accounts and unnecessary privileges
- Confirm security updates are being applied
- Identify unmanaged devices
- Review endpoint and malware protection
- Check firewall and remote access configurations
- Record exceptions in a risk register
These are also useful early controls for an ISO 27001 programme. The difference is that ISO 27001 requires a broader, risk-based management system around the controls, including ownership, evidence, supplier management and continual improvement.
Days 31–60: Rationalise the estate and design the target state
The second month turns information into decisions.
Apply a simple decision framework
Every major application, contract and service should receive one of four decisions:
- Keep – it is valuable, secure and appropriately priced.
- Consolidate – another platform can provide the same capability.
- Retire – it has limited value or is no longer required.
- Replace – it creates unacceptable cost, risk or operational friction.
This is where strategic Technology Expense Management becomes commercially useful. Compare actual usage with licence allocation. Review duplicate applications. Check whether support agreements overlap. Examine cloud storage, test environments, mobile connections and connectivity contracts.
A secondary internet circuit may look expensive until the primary connection fails. A premium application licence may be unnecessary for most users. Rationalisation requires judgement, not blunt reduction.
Plan Dynamics 365 Business Central properly
For businesses considering or improving Microsoft Dynamics 365 Business Central, the Dynamics 365 Jump Start phase should begin with operating requirements rather than product configuration.
Review:
- Finance and reporting processes
- Purchasing, sales and inventory
- Warehouse and distribution requirements
- User roles and segregation of duties
- Data quality and migration
- Integrations with existing applications
- Workflow and approval requirements
- Reporting and management information
- Licence requirements by role
- Training and post-launch ownership
There is increasing demand for a Business Central Functional Consultant UK businesses can trust to translate operational requirements into a workable platform design. That role should not be confused with a licence sales function. The priority is to establish the right operating model, then select the appropriate implementation and execution specialists.
A well-run Dynamics 365 Jump Start reduces rework, limits unnecessary customisation and prevents the organisation from creating a new collection of disconnected tools around its ERP.
Design Disaster Recovery around tested objectives
By Day 60, the business should have a written Disaster Recovery design for each critical service.
The design should define:
- Target RTO and RPO
- Backup frequency and retention
- Off-site or geographically separate copies
- Recovery dependencies
- Supplier responsibilities
- Decision-making authority
- Internal and external communications
- Restoration and validation steps
For Business Central, review the platform’s resilience arrangements, data export requirements, integrations and operational dependencies. For IBM i Management, document backup routines, recovery environments, specialist contacts and the steps required to restore business applications.
A backup that has never been restored is a theory. A recovery objective that has never been measured is a budget assumption.
Clarify the role of Managed IT Services
Managed IT Services, Helpdesk Support, Network Solutions and Voice and Connectivity can all be valuable execution services. They should, however, operate within the wider IT strategy.
Define who is responsible for:
- First-line user support
- Security monitoring
- Patching and device management
- Network changes
- Connectivity suppliers
- Hardware lifecycle
- Cloud administration
- Business application escalation
- Strategic technology decisions
This avoids the familiar situation in which several suppliers are active but nobody owns the outcome.
Days 61–90: Test, measure and embed governance
The final month is where the plan earns its credibility.
Test Disaster Recovery in practice
Run at least one technical recovery test and one tabletop exercise.
A technical test might involve restoring a representative dataset, recovering a server or validating an IBM i Management recovery procedure in a test environment.
A tabletop exercise might simulate:
- A ransomware incident
- Loss of a primary site
- A major cloud service outage
- An unavailable finance system
- A compromised administrator account
- A failed Voice and Connectivity service
Measure the actual recovery time and earliest recoverable data point against the agreed RTO and RPO.
Record:
- What worked
- What failed
- Who made decisions
- Which supplier dependencies caused delays
- Whether contact details were current
- Which steps were unclear
- What must change before the next test
The aim is not to produce a perfect test result. It is to discover weaknesses before an incident does.
Complete the rationalisation decisions
By Day 90, each major technology cost should have a documented position. Create a forward plan for:
- Licence reductions and renewals
- Contract renegotiation
- Cloud usage review
- Connectivity consolidation or resilience
- Hardware replacement
- Application retirement
- Business Central implementation activity
- Specialist IBM i Management
- Cyber Essentials certification
- ISO 27001 improvement priorities
Track expected savings separately from realised savings. A planned licence reduction is not yet a saving, and a saving that weakens recovery capability is not necessarily a good decision.
Establish the quarterly control cycle
The programme should continue after Day 90 through a light but disciplined governance rhythm:
- Monthly review of security and recovery indicators
- Quarterly Technology Expense Management review
- Quarterly licence and access review
- Annual Disaster Recovery exercise
- Regular supplier and contract review
- Management review of ISO 27001 risks and improvement actions
- Periodic testing of critical recovery procedures
This is the practical expression of the Fractal IT Director approach: the commercial, operational and technical picture is reviewed as one system rather than as a series of disconnected supplier conversations.
Evestaff IT Support and Consultancy can provide the strategic IT leadership required to shape this plan, using specialised channel partners where specific technical execution or scale is needed. The wider Evestaff group can be reached through evestaff.co.uk.
The best outcome is not the cheapest technology estate. It is a controlled one: where every significant cost has a purpose, every important risk has an owner and every critical service has a recovery plan that has been tested.
