Solution Design

Every Strong Build Starts With a Strong Plan.

i4 Integrated Services Limited designs the architecture and documentation that turn ideas into buildable, scalable technology solutions — before the first line of code commits you to anything.

The drawing board

Four blueprints. One buildable plan.

Before a single line of code is written, we put the whole solution on paper, so your team builds it right the first time.

Sheet 01 / 04

System Architecture Design

A clear technical blueprint of how your system's components will work together. It gives your development team a shared, reliable reference point from day one.

  • System structure and component mapping
  • Database architecture and data modelling
  • Infrastructure, cloud, and network architecture
  • Security architecture and access control design
  • Technology stack evaluation and recommendation
  • Scalability, performance, and high-availability planning
Sheet 02 / 04

Technical Specification Document

Detailed documentation outlining exactly how a solution should be built. It removes guesswork from development, keeping every stakeholder aligned on what's actually being built.

  • Functional and technical requirements specification
  • Detailed technical design specification
  • Database design and logical data models
  • API and integration interface specifications
  • Implementation guidelines written for build teams
Sheet 03 / 04

Complete Solution Blueprint

An end-to-end plan covering architecture, specifications, and implementation strategy. It connects the technical details to your business goals in a single, actionable document.

  • Business process and workflow modelling
  • Solution blueprint and architecture diagrams
  • Disaster recovery and business continuity architecture
  • Implementation roadmap and deployment strategy
  • Architecture validation and review report
Sheet 04 / 04

Enterprise Architecture Planning

Strategic, organization-wide technology planning aligned with long-term business goals. It helps leadership make confident, informed decisions about where technology investment should go next.

  • Enterprise-wide systems and current-state assessment
  • Enterprise architecture blueprint
  • Long-term technology roadmap
  • Alignment between IT strategy and business objectives
  • Architecture governance and compliance guidance

Planning something big?

Let's design it right
What gets designed

Nine layers, decided deliberately

An architecture is only as strong as its weakest unexamined assumption. Each of these is designed, documented, and reviewed rather than left to be worked out during the build.

L01

Application architecture

How the solution is decomposed into components, services, and modules, and how each one is expected to behave.

L02

Data architecture

Database design, logical data models, and how information moves and is stored across the solution.

L03

Infrastructure & cloud

Hosting topology, environments, and cloud services sized against real workload and growth assumptions.

L04

Integration & API

Interface specifications and integration patterns for connecting to the enterprise systems already in place.

L05

Network & communication

Connectivity, segmentation, and communication paths between components, environments, and external parties.

L06

Security & access

Identity and access management, data protection, and security controls designed in rather than retrofitted.

L07

Scalability & performance

Capacity planning, performance targets, and high-availability design for the load the system will actually see.

L08

Resilience & recovery

Disaster recovery and business continuity architecture, decided deliberately instead of discovered in an incident.

L09

Technology selection

Platform and stack evaluation against business fit, skills availability, cost, and long-term supportability.

Why it matters

Projects rarely fail at the build. They fail at the plan.

Most cost overruns and redesigns trace back to decisions that were never made explicitly — or were made by whoever hit the problem first.

Where projects start

Building without a blueprint

  • No defined technology architecture aligned to business goals
  • Disconnected applications, databases, and business systems
  • Scalability and performance treated as a later problem
  • Inadequate security architecture and risk management
  • Complex integration requirements discovered mid-build
  • Unclear technology selection and infrastructure planning
  • Thin documentation, leaving implementation teams to guess
  • Cost overruns and delays caused by repeated redesigns

Where the engagement leaves you

An implementation-ready design

  • One architecture that traces directly back to business objectives
  • Every layer — application, data, infrastructure, network, security — designed as a whole
  • Integration interfaces specified before anyone commits to a build
  • Technology selected on evidence, with the evaluation written down
  • Scalability, availability, and recovery designed in from the start
  • Specifications detailed enough for a development team to execute
  • A sequenced implementation roadmap and deployment strategy
  • Architectural decisions your leadership can defend and revisit
How we work

From first workshop to signed-off pack

Four phases, each closing with named artifacts and your approval.

  1. 01

    Discovery & Requirements Analysis

    Understand the business, the systems already in place, and the constraints the design has to work within before any architecture is drawn.

    What happens

    • Stakeholder engagement and interviews
    • Business process analysis
    • Requirements gathering and validation
    • Current-state systems and infrastructure assessment
    • Architecture planning

    What you receive

    • Business Requirements Specification
    • Solution Requirements Document
    • Current-State Assessment Report
  2. 02

    Enterprise & Solution Architecture Design

    Design every layer of the solution and evaluate the technologies it will be built on, as one coherent architecture rather than separate decisions.

    What happens

    • Application and data architecture design
    • Infrastructure, cloud, and network architecture
    • Integration and API architecture
    • Security architecture and access control design
    • Technology stack evaluation

    What you receive

    • Enterprise Architecture Blueprint
    • Solution Architecture Document
    • Architecture diagrams
  3. 03

    Technical Design, Blueprint & Validation

    Take the architecture down to the level of detail a development team can build from, then validate it before it is signed off.

    What happens

    • Detailed technical specifications
    • Database models and process flows
    • API specifications and security controls
    • Architecture review workshops and technical validation

    What you receive

    • Technical Design Specification
    • Technical Blueprint
    • Architecture Review & Validation Report
  4. 04

    Documentation & Implementation Planning

    Package the design, sequence the work, and hand it over so the teams who build it know exactly where to start.

    What happens

    • Implementation roadmap and deployment strategy
    • Technical documentation preparation
    • Knowledge transfer sessions
    • Stakeholder presentation and sign-off

    What you receive

    • Implementation Roadmap
    • Deployment Strategy
    • Final Architecture Pack
    • Knowledge Transfer Materials
What you receive

The architecture pack

Not a slide deck and a verbal handover. A complete, versioned document set that your development team, your integrators, and your auditors can all work from.

Document index15 artifacts
  1. 01Business Requirements Specification (BRS)
  2. 02Solution Requirements Specification (SRS)

  12. 12Scalability, High Availability & Disaster Recovery Design
  13. 13Implementation Roadmap & Deployment Strategy
  14. 14Architecture Review & Validation Report
  15. 15Technical Documentation & Knowledge Transfer Materials

The exact composition of the pack depends on the scope agreed at discovery — a single-solution blueprint will not need every enterprise-wide artifact, and we would rather tell you that than bill for pages nobody reads.

Security, compliance & assurance

Designed secure, then reviewed before it is signed

Security is an architectural decision, not a phase at the end. Every design is validated against these before the pack is issued.

Applied at every phase

Security framework

  • Security-by-design across all architectural components
  • Identity and access management architecture
  • Data protection, privacy, and information governance
  • Secure application, infrastructure, and API architecture
  • Network security and communication architecture
  • High availability and business continuity planning
  • Disaster recovery architecture
  • Scalability, performance, and capacity planning
  • Compliance with applicable standards and regulations
  • Alignment with your internal security policies

Before anything ships

Quality assurance

  • Architecture quality reviews at each milestone
  • Technical validation of every design decision
  • Stakeholder architecture review workshops
  • Technology feasibility assessment before recommendation
  • Integration compatibility assessment
  • Documentation quality assurance
  • Traceability from requirements to design
  • Formal sign-off before the pack is issued
Why i4

Why organizations bring the architecture to i4 first

The cost of a wrong architectural decision is not the design fee. It is the eighteen months spent building on it.

Architecture before code

The design is finished, reviewed, and signed off before development starts — which is where most implementation risk is actually removed.

Recognized frameworks

Internationally recognized architecture principles and structured design methodologies, not one architect's personal preferences.

Multidisciplinary review

Enterprise architecture, cloud, cybersecurity, systems integration, and infrastructure specialists reviewing the same design.

Documentation teams can build from

Specifications, diagrams, and data models written for the developers and integrators who have to execute them.

Independent of the build

We can design a solution without being the party that implements it, so technology recommendations stay driven by fit rather than convenience.

Advisory through implementation

Post-engagement support to clarify, validate, and govern the architecture while it is being built.
