How the project started

People often enter professional roles with access to powerful workplace systems and little structured guidance on how those systems should be used together. Training jumps to advanced features of a single product, or to workshops that never touch a folder structure, a meeting note, or a table of figures. The gap appears later as duplicated files, meetings without decisions, and reports that cannot be checked.

Slusk grew from that observation. Contributors had spent years in adult digital-skills teaching and in supporting internal training, and kept seeing the same practical failures: tools adopted without method, collaboration reduced to more meetings, and data shared without anyone asking what the numbers meant. The response was to organise those observations into self-contained programmes that could be used independently, at the learner’s own pace, with diagnostic checklists instead of motivational language.

Important: Slusk and Poli Kaak B.V. provide educational practice materials only. They do not offer workplace consulting, career placement, or product endorsements.

Principles

  • Practice before display — process and observation come first
  • Diagnosis over judgement — specific, correctable issues rather than vague praise or criticism
  • Tools as methods — how shared systems are organised, not which brand to buy
  • Honest scope — foundational skill, not career guarantees or management training
  • Self-directed access — materials remain available for repeated use after enrolment

The team

Content is developed by a small group with experience in adult digital-skills instruction, information practice, and learning design.

Programme design

Marjolein shapes the overall sequence of programmes. She has taught adult digital skills in the Netherlands and supported internal training in public organisations. She keeps the material practical and free of outcome promises.

Workplace tools

Koen develops modules on shared workspaces, document versions, and everyday platform habits. His background is information management; the emphasis is on how people actually use tools, not on product features.

Collaboration practice

Sanne writes remote-collaboration scenarios and meeting exercises. She has coordinated distributed project work across European and Canadian time zones and treats written records as essential working tools.

Digital information

Jeroen looks after data-handling and spreadsheet practice. He comes from an operations background and focuses on how ordinary tables go wrong, and how a careful reader notices.

Learning design

Iris shapes exercises, checklists, and pacing so that each unit has a concrete task a learner can finish in one sitting and then assess against published criteria.
