Mahthildis Method
A clear method, from decision to delivery.
Mahthildis shapes the engagement around your situation: understand the stakes, set a trajectory, steer the people involved and support delivery through to the agreed result. These are not three mandatory stages.
Decision, leadership, result
1
Decision
Understand the problem and choose the trajectory.
2
Leadership
Coordinate teams, vendors and execution.
3
Result
Move the project toward the agreed outcome.
Possible formats
Which format helps you move forward?
A first conversation, a diagnostic or ongoing support, according to the need. These are suitable formats, not mandatory successive purchases.
Possible format
Decision Diagnostic
A suitable format when a structured analysis is needed before committing to a decision, a budget or a project. It is not a mandatory entry point: depending on the situation, Mahthildis can also step in directly with advice, project leadership or operational delivery.
Possible format
Tech Sparring Partner
A specific format for a team that already has its own steering. It is used to challenge a decision, compare options and examine risks with the CTO, CIO or their team, without taking over leadership.
Targeted contribution
The right specialist expertise for the question that requires it
Some decisions need a specialist view. Paulo Castro remains responsible for the coherence of the engagement. Expertise is brought in according to need, within an agreed scope — not as consultants on time-and-materials.
Architecture & IT modernisation
Design or evolve the system, without defaulting to a full rebuild.
ERP & interfaces
Choose, migrate or see an ERP through, including system exchanges.
Cloud & cost control
Examine expenditure, availability and dependencies before committing budget.
Cybersecurity & personal data protection
Separate technical controls from questions to review with the relevant specialist.
Project oversight & governance
Hold milestones and decisions, and take on a defined delivery scope.
Software quality & technical trajectory
Clarify maintainability and risk before continuing, taking over or replacing.
Vendor choice & coordination
Compare, reframe and coordinate without opaque time-and-materials dependency.
Data, AI and automation
Frame, integrate and deliver a useful case, with human validation.
Example: connecting an AI assistant to internal tools means examining the use case, data, access, reliability and cost. The mission lead coordinates the contributions required and formulates a recommendation. These contributions are neither systematic nor automatically included in a first conversation.
Why Mahthildis
One senior counterpart, from problem to result
You speak directly with Paulo Castro, who remains responsible for the coherence of the engagement. Depending on the need, Mahthildis can advise, design, steer or take on the delivery of a defined scope, working with your teams and vendors. When other expertise is required, it is coordinated inside the mission — without selling a bench of contractors.
