RHJM LLC opens new study engagements this quarter — all six service files are available to organisations across professional, scientific and technical services.

Opening File Studies

The six service files in full

Read each file as a standalone note or as one part of a longer programme. Together they cover the whole arc of an integrated systems modernisation.

FILE A

Systems Architecture Studies

A systems architecture study begins with the estate as it truly is, not as the last diagram described it. We inventory every application, integration, data store and hosting location, then trace the actual flows between them using logs, configuration and conversations with the people who operate the systems each day. The gap between the documented architecture and the working one is usually where the most expensive problems hide.

Once the picture is assembled we assess each component against the business capability it supports and score it for criticality, fragility and cost of ownership. Structural weaknesses are separated from cosmetic ones, and each finding is tied to observable evidence. The study concludes with a target architecture described in plain terms, a set of prioritised recommendations and an explicit list of what should be deliberately left unchanged. Deliverables include a component map, an interface register, a debt register and a decision log that can be handed to any delivery team.

FILE B

Integration Roadmapping

An integration roadmap turns architectural findings into a sequence of achievable moves. We map every dependency across systems, teams, suppliers and budget owners, then group the work into phases that each end in a position the business can use. Early phases are chosen to retire the highest risk with the least disruption, so that confidence and evidence grow together.

The roadmap records the assumptions behind each estimate, the decisions that must be made before a phase can start, and the signals that would justify changing course. Cost is presented in ranges with the reasons for the range made clear. We also define the operational cut over approach for each phase, including rollback positions and the support arrangements that protect service continuity. The result is a plan that survives contact with reality because it was built to be revised rather than defended.

Data Migration Analysis

Data migration analysis starts with profiling. We measure duplication, completeness, encoding consistency, orphaned relationships and ownership across every source system that will feed the target platform. The profile exposes the true scale of cleansing work long before extraction begins, which is the single most effective way to keep a migration on schedule.

From the profile we design the migration posture: what moves as is, what is transformed, what is merged, what is archived and what is retired. Validation rules are written for each entity so that correctness is proven by evidence rather than assumed. We then plan a full rehearsal against production-like volumes to measure duration, confirm reconciliation totals and refine the cut over runbook. Deliverables include the source profile, the transformation specification, the validation protocol and a rehearsal report with a signed off reconciliation position.

FILE D

Platform Consolidation Plans

Platform consolidation reduces both direct cost and the hidden cost of keeping overlapping tools consistent. We catalogue every platform in a capability area, quantify licence, hosting, support and staff effort over the remaining life of each, and identify which capabilities are genuinely duplicated rather than merely similar.

The consolidation plan sets a retirement order that begins with the safest candidates and protects the capabilities the business depends on most. For each platform we document the migration route for its data and integrations, the licensing exit terms, the retention obligations that may outlive the system, and the training needed so that users adopt the surviving platform fully. We also model the break even point so that leadership can see when the investment in consolidation returns more than it costs. Deliverables include an overlap matrix, a cost of ownership model, a sequenced retirement plan and a benefits tracking baseline.

FILE E

Risk and Compliance Reviews

A risk and compliance review examines how the estate handles access, data, retention and supplier dependency against the obligations that apply to each client. We trace who and what can reach each system, where data travels, how long it is kept and which third parties touch it. Each finding is ranked by real world impact, considering likelihood, blast radius and the cost of recovery.

Every finding is paired with a proportionate control and a named suggested owner, so the register becomes an actionable document rather than a compliance ornament. Where obligations overlap we harmonise the controls to avoid duplicated effort. We also review the evidence trail: whether the organisation can demonstrate compliance to an auditor or regulator without a scramble. Deliverables include a ranked risk register, a control recommendation set, a supplier dependency view and a remediation sequence aligned to the wider roadmap.

FILE F

Managed Modernisation Programmes

Some modernisation programmes run for years and outlive the teams that started them. For these engagements RHJM LLC provides continuing programme leadership that keeps the original analysis alive. We maintain the roadmap, chair the decision forums, track benefits against baseline and adjust the sequence as the estate and the business evolve.

Reporting is deliberately direct. Leadership receives a single programme scorecard showing progress, risk, spend against forecast and the decisions now required, written so that technical and commercial readers see the same position. We also protect institutional memory: every change of direction is recorded with its reasoning, so a new programme manager can pick up the scoresheet and continue without replaying old arguments. The programme can absorb new priorities without losing its shape because the underlying analysis is maintained as a living artefact rather than a filed report.

Process Overview

How an engagement runs

Every file follows the same four phase rhythm, adjusted to the size of the position on the board.

STEP 01

Survey

Documents, interviews and direct observation produce an honest picture of the current estate and the constraints around it.

STEP 02

Analyse

Findings are tested against capability, cost and risk, and competing lines of action are worked through in writing before any recommendation is made.

STEP 03

Recommend

A preferred sequence is delivered with dependencies, assumptions and a clear account of what could change the advice.

STEP 04

Support

Where required we remain in the programme, maintaining the plan and reporting progress until the position is settled.
