The Challenges

Fedrus International has grown very fast through mergers and acquisitions. This implies that data is spread over different applications, systems and processes.  These challenges translate in multiple interviews with business owners, old and new systems and changing IT landscape. People are very busy and also located in multiple locations (Puurs, Deinze and Kampenhout).

  • Plan meetings / interviews with all these Subject Matter Expert’s (SME);
    • CRM, ERP, Sales, Logistics, Finance
    • Marketing
    • HR, Health and Security
    • IT, DWH and BI
  • Explain General Data Protection Regulation (GDPR), our way of working and show the deliverables.


As transparency about "data" is a key driver of the regulation, an important step will be to understand how your business is "processing" personal data and what personal data you record, store and process in the first place. This requires a deep dive in all your "processes" and "systems" to get a better understanding of all data flows with special focus and attention on the "personal" data flows.

A phased approach towards GDPR compliance requires a proper methodology and a skilled team (consisting of lawyer, data architect, process owners, application owners, IT architect, …).

Typical steps in this phased approach are:

  • Knowledge & Awareness
  • GDPR Readiness Scan
  • GDPR Assessment (this phase will focus on data mapping and data flows within your organization and application landscape)
  • Roadmap to Compliance

We have developed a methodology that will facilitate the creation of key deliverables to enable your organization to prepare for "Roadmap to Compliance". 

These deliverables consist of:

  • Data mapping document (5Ws)
  • Data flow diagram

Data mapping document – 5Ws

Data mapping allows you to identify the information that your organization keeps and how it moves from one location to another, such as from suppliers and sub-suppliers through to customers. By mapping the flow of data, you’ll be able to review the most effective way of processing data and identify any unforeseen or unintended uses.

The 5Ws document will help you to cover the details of personal data by working around 5 ‘W’ questions:

GDPR data mapping for Roof Construction Distributor

Why … is personal data processed?

      Whose … personal data is processed?

What … personal data is processed?

       When … is personal data processed?

             Where … is personal data processed?

Data flow diagram

The data flow diagrams, which are a high-level graphical representation of the flow, are typically created by process.  They will help to understand the information lifecycle and represent all in- and cross application flows.


This exercise is typically executed by a data architect together with both functional and technical application and process owners within your organization and facilitated by interviews and workshops.

With these deliverables the Fedrus International Data Protection Officer (DPO) and legal advisor can facilitate the next steps which typically consist of the creation of “Register of Processing Activities” (RoPA) and “Technical and Organisational Measures” (TOMs).
