Before, we deep dive into the digital transformation one thing that we might forget is interoperability. Interoperability can be said as a readiness index of any solution that needs to go to the digital transformation initiative. Just imagine you already built a web application to support member to create a financial plan. Then, you think that you need integration such as saving your investment to Investment provider, storing the money into stocks, or saving it into the cashless provider. The integration scenario won't be done without interoperability.
Based on the example, we found that putting interoperability in a new system is easier than the legacy system. So the real question is, how you build a solution with interoperability in mind. This video will help you to answer the question (the video is in Bahasa if you need the English one feel free to comment on it)
