Methodologies & Standards We Work With.
Portamus consultants are certified in and practise the leading enterprise architecture, service management, and process improvement frameworks. We apply these methodologies to your context — pragmatic, not off-the-shelf.
Framework Challenges We Solve
Most clients come to us with a challenge, not a framework name. Find yours below.
No common architecture language
Departments use different tools, notations, and vocabularies — making architecture communication and governance impossible.
IT service delivery is inconsistent
Service quality varies, incidents recur, and there's no structured approach to service improvement.
Processes are undocumented or informal
Business-critical processes live in people's heads — creating risk, inefficiency, and barriers to change.
Failed technology programmes need rescue
An ERP or transformation programme has overrun and needs structured programme recovery.
Benchmarking against industry standards
Leadership needs to demonstrate architectural maturity to auditors, partners, or the board.
Training teams on EA frameworks
Internal staff need upskilling in TOGAF, ITIL, BPMN, or ArchiMate for a self-sustaining capability.

Trusted to Get the Architecture Right
A framework is a tool, not the goal. The real value is in how it changes decision-making and architecture governance across the organisation.
Dr. Marcel Rosenberger, Managing Director, Portamus GmbH
A Framework Is a Tool, Not the Goal
Here's what clients actually walk away with after a framework-led engagement.
Establish a Common Architecture Language
Teams speak the same language — TOGAF, ArchiMate, or BPMN — reducing communication overhead.
Accelerate Governance Decision-Making
Architecture boards operate from documented principles rather than ad hoc consensus.
Reduce Programme Risk
Structured frameworks reduce scope creep, rework, and failed delivery in transformation programmes.
Demonstrate Architecture Maturity
Benchmarked maturity scores show progress to leadership, auditors, and the board.
Upskill Internal Teams
Framework training builds a self-sustaining internal capability beyond the engagement.
Support Business Growth
A governed architecture scales predictably as the organisation grows or enters new markets.
