GGIM EA Profile
FrostLine optional
Architecture decisions shape how business processes operate, how information is protected, and how much complexity and cost the organization carries.
We help organizations evaluate and design the systems supporting agreed business processes. We bring enterprise and security architecture together to compare options, develop conceptual and logical designs, and document the decisions, tradeoffs, and remaining questions that guide implementation.
BUSINESS REQUIREMENTS. EXPLICIT TRADEOFFS. TRACEABLE DESIGN DECISIONS.
Enterprise Architecture|
Connect business capabilities to architecture capabilities, system responsibilities, and reusable patterns.
Security Architecture |
Integrate threats, trust boundaries, and protection requirements into the design.
Architecture Without a Shared Design Basis.
Leadership and delivery teams need a shared basis for comparing architecture options, understanding their consequences, and deciding what is ready to proceed and what needs further work.
01
The Problem
Business requirements, technology designs, and security reviews are often developed separately. Decisions can advance without a shared understanding of process needs, data flows, dependencies, threats, and operating constraints.
Security requirements emerge late, important assumptions remain untested, and delivery teams inherit design choices whose rationale is unclear. Resolving these issues after implementation can require significant rework.
02
Why It Matters
Architecture choices affect business performance, security, resilience, operating costs, and the organization’s ability to change.
Evaluating these consequences together helps leadership choose designs that meet business needs while understanding the dependencies, risks, and commitments they introduce. Clear decisions also give delivery teams a consistent basis for implementation and validation.
We connect business requirements, architecture capabilities, and security needs to a documented design and decision package, making the rationale, tradeoffs, dependencies, and remaining validation needs explicit.

Questions the Engagement Answers
Eleven questions guiding the architecture assessment, comparison of design options, and decisions needed to support implementation.
THE ARCHITECTURE DECISION QUESTIONS
11
Questions addressed through business requirements, architecture analysis, and explicit design rationale.
Design choices linked to business requirements
Options compared with tradeoffs and dependencies explicit
Assumptions and validation needs carried into the handoff
Primary handoff:
ARCHITECTURE DECISION PACKAGE
The architecture decision package records the recommended decisions and supporting rationale, distinguishing what has been resolved from what requires further design, evidence, or approval.
01
Which business outcomes and process requirements must the architecture support?
02
What responsibilities should each system or component perform?
03
How should applications, data, identities, and services interact?
04
Where are the trust boundaries and critical dependencies?
05
Which threats and security requirements must the design address?
06
How do the proposed options affect security, resilience, performance, and operational complexity?
07
Which existing patterns are suitable, and where is a justified exception needed?
08
What are the implementation and ongoing operating implications of each option?
09
Which design best meets the agreed requirements, and what tradeoffs does it introduce?
10
Which assumptions, remaining risks, or unresolved questions require validation before implementation?
11
What evidence will be needed to confirm that the implemented solution meets the design requirements?

How the Architecture Decisions Connect
THE GGIM EA PROFILE
11
Eleven connected elements, from business capability to architecture decision.
/ Options compared against agreed requirements and constraints.
/ Rationale, tradeoffs, assumptions, and consequences documented.
/ Design conformance and adequacy assessed together.
EXPLORE THE ARCHITECTURE TRACE
We assess both conformance with applicable standards and whether the design addresses relevant business needs and threats. Projected changes in exposure are explained with their supporting assumptions. Financial risk quantification can be scoped separately where needed.
01
Business Capability
What the organization must be able to do, realized through the selected business processes.
02
Architecture Capability
The technical abilities needed to support those processes, independent of specific products.
03
Architecture Building Block
The functions and responsibilities required to provide an architecture capability.
04
Solution Building Block
The existing or proposed solutions selected to realize those functions.
05
Pattern / Reference Architecture
How the building blocks should fit together, including relationships, flows, and design constraints.
06
Asset / Application
The existing or proposed systems that realize the design and support the business processes.
07
Requirements & Security Capabilities
What the design must satisfy and the protection capabilities available or needed to support it.
08
Controls
How protection requirements are intended to be implemented and applied within the design.
09
Conformance
Whether the design follows applicable standards and patterns, with deviations identified and justified.
10
Projected Exposure
How the proposed design could change exposure to relevant threats, with supporting assumptions stated.
11
Architecture Decision
The recommended option, its rationale and tradeoffs, and the remaining risks, validation needs, and approvals.
We connect the selected business processes and their intended outcomes to the system capabilities, information flows, dependencies, and security requirements needed to support them.

What GGIM connects
For Each Architecture Decision
Which business needs the design must support
1. Business Processes & Capabilities
2. Architecture Capabilities & Building Blocks
Which technical abilities and system responsibilities are required
3. Systems & Dependencies
How applications, services, and supporting systems interact
4. Data, Identities, & Flows
What information moves, who can access it, and where trust boundaries lie
5. Requirements & Controls
What the design must satisfy and how protection is intended to work
6. Patterns & Reference Architectures
Which reusable designs apply and where deviations need justification
7. Decisions & Supporting Rationale
Why an option is recommended and what assumptions remain to be validated
GWS uses the GGIM EA Profile to connect business processes and capabilities with the systems, data, identities, requirements, controls, and dependencies relevant to an architecture decision.
These relationships provide context for evaluating design alternatives and tracing recommendations back to business needs. They also help identify which requirements and decisions may need review when the architecture changes.
GWS provides the advisory judgment. GGIM structures the architecture relationships and decision rationale. The engagement can be delivered with or without FrostLine.
OPTIONAL FROSTLINE Snapshot
Where appropriate, a FrostLine Snapshot can contribute point-in-time diagnostic evidence to the assessment. Its role and coverage are defined within the engagement scope.
What It Looks Like and How to Reach Out
A focused engagement built around agreed business processes and architecture decisions. Scope, design depth, and timing are agreed during the initial discussion.
How to Reach Out
Discuss Your Architecture Decision
Tell us which architecture decision you are facing. We will arrange an initial discussion to explore the business context, options, and design support needed.
Start with an architecture decision: introducing a platform, redesigning an integration, consolidating applications, changing access arrangements, or improving resilience.
We use an initial discussion to identify the affected business processes, the options under consideration, and the design depth needed to support approval and delivery.
Glacial Wolf Strategy provides architecture advisory and decision support. The Enterprise & Security Architecture engagement is not an audit, certification, attestation, or legal opinion.
The initial discussion covers
1
Architecture Decision
What change are you considering, and which options need to be evaluated?
2
Business Processes & Requirements
Which processes must the design support, and what outcomes, dependencies, or constraints matter?
Design Depth & Approval Needs
What architecture outputs, stakeholder approvals, and delivery considerations must the engagement address?
