ERP Architecture
in complex environments
where decisions cost millions

I help companies stabilise and develop ERP and related systems where their complexity and interconnections start to hinder growth. Leadership gains a clear decision-making framework and control over risks and vendors.

Effective architecture and integration, clear system responsibilities, financially and operationally sustainable transformation.

When does collaboration make sense

IS investments are growing, but results are not coming. I help identify bottlenecks and direct resources properly. I often try to stabilise and optimise what has already been invested in, rather than pursuing new complex solutions.

I frequently step into situations where management and IT see the problem differently. I help name the real cause based on data, not impressions or vendor pressure.

When CEOs reach out to me
Before deciding on ERP replacement or a major investment
When IT investments are not delivering expected results
When tension arises between management and IT
ERP replacement decisions without clear impact assessment
When CIOs reach out to me
When designing target architecture
When managing complex integrations
When a realistic transformation plan needs to be justified
When there is pressure for quick decisions without knowing the impacts

Logistics & distribution

An investment that could wait

A distribution company planned a costly ERP optimisation due to growing B2C orders. I quantified the actual workload for the current order volume and found that even with significant growth, the existing system could handle the processing. We monitor the load to catch the need for optimisation early and invest only when truly necessary.

Group of companies

One company's problem, not the whole system's

A large group of over eighty companies considered a complete ERP replacement. Data and process analysis revealed that the issues were caused by a single company. We proposed a targeted optimisation — at a fraction of the cost of a new system and without burdening employees with a large-scale implementation.

ERP as the foundation of regulated processes

Together with business owners, we design support processes for pharmaceutical specifics and regulations. We are gradually eliminating paper documents and duplicate data entry across systems. We made ERP the foundation of all downstream processes. Less rewriting, less manual work.

What I do specifically

After familiarising myself with the current situation, I look for solutions with emphasis on financial, personnel and business sustainability. I define the steps needed to reach the target state and oversee their safe and controlled execution.

The role is architectural and strategic — it is not about ERP configuration or administration. In this engagement I am neither an implementor nor a reseller of any specific technology. The goal is to create a framework where implementation makes sense and is managed safely.

Target state definition

  • Overall architecture design
  • Defining responsibilities between systems
  • Integration framework specification

Supervision & risk management

  • Defining a safe transformation approach
  • Team and vendor supervision
  • Advisory for CEO / CFO / CIO

What I bring to leadership

Ability to quantify decision impacts (performance, volumes, people workload)
Orientation in the implementation reality of ERP projects
Independent perspective outside individual vendor interests
Translation between IT language and management language

Industry experience

From mid-size companies to large groups with dozens of interconnected entities.

Healthcare

Facility groups with multiple operations, NIS, LIS integration, workflow.

Pharmaceuticals

Internal tools, compliance, external integrations, EDI.

Logistics and distribution

B2B → B2C transformation, combining both relationship types in one environment

Manufacturing

10+ years with mid-size companies on ERP implementation and integration.

Cooperation model

Advisory / part-time engagement (1–2 days per week), or project-based approach.

I typically enter environments where an IT team and vendors already exist. My role is to structure decision-making and reduce risks, not to replace their responsibility.

Environment orientation — analysis of architecture, integrations, risks. — analýza architektury, integrací, rizik.
Target state definition — ERP role, responsibilities, integration map. — role ERP, odpovědnosti, integrační mapa.
Approach definition — priorities, milestones, governance. — priority, milníky, governance.
Supervision — working with vendors, change management. — práce s dodavateli, řízení změn.

About me

I started my career as an ERP consultant in manufacturing and logistics. Over time I expanded my scope to include reporting, accounting, custom development and integration of other systems (WMS, e-shop, NIS, LIS).

I am a co-founder of a consulting firm. The company implements two ERP systems (manufactures none) and delivers custom development and integrations.

Thanks to my experience from the environment of the largest Czech ERP vendor, I understand the business and implementation strategies of IT companies and what typically happens during projects.

Today I focus on the architectural and decision-making level — I help leadership and IT departments clarify the target state and a safe transformation approach.
