1. Start from small part, Design Thinking is not something that can instantly change an entire organization overnight. Because it is something that must gradually let employees adjust their concepts and begin to gradually practice all 5 processes. So, we should start with a small group or project first. Otherwise, start with a team or group of employees tweaking the idea and trying it out by working on a small project as an experiment, use Design Thinking techniques to apply and then gradually expanding the circle wider.

2. Assign those who will learn first and those who will teach and motivate the rest of the staff to bring new concepts or ways of working into use in the organization. There is always a group of people who accept new things and apply quickly. It may be someone who has previous knowledge or experience or someone who is ready to learn new things to make these first groups spread knowledge and motivate others to create a network of learning and knowledge spreading. Or creating champions of each division that drive and teach ot

3. Avoid working in silos between teams and departments. Design Thinking is the use of cross-functional knowledge and the collaboration of many departments. This is most helpful if brainstorming is done, also sharing ideas from people who have experience with ideas, then various perspectives come together. Therefore, if there is a practice or trial project, there should be people from different teams working together.

4. Understand that Design Thinking is a dynamic process that is not tied to a chain of command. In the work process, each step is not required to follow a chain of command. And there is no need to follow each step. It ;s able to skip steps and come back again. No need to start with Empathize, Define, Ideate, Prototype and Test. Follow this for every problem and be able to jump oversteps according to the nature of each problem.

5. State clearly how success will be measured. How will the organization communicate and identify the success measures of the Design Thinking implementation? There must be a system to measure progress on the job. Are there any projects that use Design Thinking in their work or measuring employee satisfaction towards applying Design Thinking in their work?

Design Thinking, like bringing anything new into an organization, takes time to truly be absorbed and understood and implemented across the organization. The organization must find a way to communicate, motivate employees to understand the benefits and implement it naturally and effectively although it takes time and effort, if done correctly, it will bring good results and create satisfaction and truly meet the needs of customers.
