Consulting
IT Strategy & Architecture
SERVICE ENGINEERING GUIDE
Translate business priorities into a technology direction that can be funded and delivered. Our advisory work connects the current estate to a target architecture, makes tradeoffs explicit and produces a sequenced change portfolio for IT leaders.
What we deliver in practice
Current-state assessment
Interview business and IT owners, inspect architecture records and identify service pain points. Separate observed facts from assumptions and prioritise gaps by business consequence.
Current-state baseline and capability heatmap.
Target architecture
Define principles for connectivity, compute, identity, data and operations. Compare retained, modernised and replaced components, with decision criteria and interdependencies documented for each option.
Target architecture and decision register.
Investment & operating model
Estimate cost categories and implementation dependencies using transparent assumptions. Define ownership, skills and supplier interfaces; avoid treating an unvalidated estimate as a procurement quotation.
Options assessment and operating responsibility model.
Transition & governance
Sequence initiatives around risk, readiness and business value. Set architecture review gates, success measures and decision owners so the strategy remains usable during procurement and delivery.

The technology, explained
HLD / LLD
A high-level design explains components and choices; a low-level design specifies implementation detail. Both should trace requirements and record approved decisions.
TCO
A lifecycle view of acquisition, licences, operation, skills, support and retirement costs. Estimates should state their assumptions and excluded items.
RACI / ownership
Clarifies who performs work, who is accountable and who is consulted or informed. Use it to resolve handoff gaps between business, IT and suppliers.
Reference architectures & design practices
Illustrative patterns for project discussions. Final topology, sizing, products and acceptance criteria are developed against your requirements. These are BrightGate concept diagrams, not vendor-certified designs.
Business-to-architecture decision model+
On smaller screens, scroll the diagram sideways to see all components.
Business outcomes drive target capabilities; architecture options are evaluated before investment waves are agreed. A governance loop checks whether delivered changes still serve the original objectives. Consulting outputs guide implementation but do not include deployment unless separately agreed.
Design practices to apply
- Record assumptions and decision criteria.
- Trace each initiative to a business outcome.
- Assign an owner to each architecture decision.
Systems, products & official references
Examples to evaluate during scoping. Selection, supported features, hardware and licences depend on the agreed solution; a product mention does not imply a certification or an included purchase.
Architecture views & patterns
Use application, integration and infrastructure views at the level needed for each decision.
Official reference Microsoft architecture patternsCapability map & options matrix
Advisory tools for comparing fit, dependencies, risk and lifecycle cost.
Roadmap & governance templates
Maintain milestones, ownership and architecture decisions as reusable management assets.
