Assertiveness

As a technical professional, subject knowledge is rarely the problem. But what happens when you need to defend that knowledge in front of a demanding project manager, or say no to an important client? Being able to present yourself professionally and firmly is essential if you want to be taken seriously. Do you find it difficult to speak up, set boundaries or take control in meetings? With Dosign Academy’s intensive assertiveness training course, you learn how to turn tension into confidence and persuasive communication in the workplace.

Lesson programme

During this in depth training course, consisting of nine half day sessions of three hours, you learn step by step how to deal with uncertainty and tension in a professional context. We look beyond superficial tips and focus on the core of your behaviour. You learn to observe objectively, identify the causes of sub assertive behaviour and gain insight into non verbal communication. Using proven theories and techniques, you learn to make clear statements, refuse requests professionally and enter into and steer business conversations with confidence.

Programme and learning objectives

This intensive pathway consists of nine half day sessions, covering the following pillars:

  • Insight and causes: what is assertiveness? Explanation of sub assertive behaviour, non verbal communication and managing tension.
  • Communication and empathy: working with assumptions, questioning techniques, objective observation and strengthening empathic ability.
  • Boundaries and language: applying Rational Emotive Therapy, using assertive language and professionally refusing requests by learning to say no.
  • Conversation techniques: conducting conversations using LSD and STAR, with specific focus on performance and appraisal conversations.
  • Presentation and practice: assertive rights, giving a speech or elevator pitch, and intensive role play, possibly with an actor, to firmly embed the theory.

One to one coaching pathways

Persoonlijke Effectiviteitstrainingen 6 dagdelen

Niet elk ontwikkelvraagstuk past in een groepstraining. Soms vraagt een situatie om persoonlijke aandacht, omdat het gaat om jouw rol, jouw communicatie of een specifiek patroon dat terugkomt in je werk. Met 1 op 1 coaching voor technische professionals werk je gericht aan werkgerelateerde vraagstukken binnen een technische omgeving. Denk aan steviger communiceren, beter omgaan met weerstand, meer invloed uitoefenen in gesprekken, leidingnemen in projecten of duidelijker positie innemen richting collega’s, klanten of stakeholders.

Het traject is persoonlijk, praktisch en direct gekoppeld aan je eigen werksituatie. Je werkt met herkenbare casussen uit de praktijk en krijgt gerichte feedback van een ervaren coach. Zo ontwikkel je gedrag dat past bij jouw rol, je technische context en de situaties waarin jij effectiever wilt worden.

Benefits

Why choose Dosign Academy?

Focus on technical practice

We train with situations you actually encounter: communicating bad news about a project schedule, addressing a colleague about agreements, or giving a technical presentation to directors.

In depth theory and models

We work with concrete, practical models that give you direct support. You learn to work with Rational Emotive Therapy to address limiting thoughts, and you use conversation models such as LSD, meaning listening, summarising and asking follow up questions, and the STAR method for performance and appraisal conversations.

Practising with a training actor

Theory only really comes to life in practice. A large part of this training course, including the final sessions, can be delivered with the involvement of a professional training actor.

In safe but realistic role play exercises, you practise your new skills and experience directly how your assertive attitude changes the course of a conversation.
