Communication 4.0 represents a challenge due to the enormous speed of digital transformation. We have reviewed external communication processes with an emphasis on the digital tools needed to effectively communicate our ideas and reach our target audience, stressing the creation of Twitter, Facebook, LinkedIn, and Instagram. We have also seen the need for a digital marketing strategy that allows us to define our objectives and the subjacent principles that govern any marketing proposal. On the other hand, we have seen the creation of an internal communication plan, highlighting the most remarkable features and the need for open and fluid communication between employees. We closed our module with a brief approach to social media metrics to evaluate the effectiveness and efficiency of our communication strategies. In short, we focused on practical creation, promoting a step-by-step vision of development and implementation. We hope this module can contribute to achieving your goals and help you to lead your future communication strategy. Remember that adaptation is a fundamental competence of the creation process and, therefore, we want to encourage you to be updated on the trends of communication 4.0 and to make the most of your efforts.
