Jerome Joubert from IBM published an article with this title listing three important factors which drive success with your decision automation project:

1. Business-oriented methodology. Let your business experts take control by discovering business decisions and validating them with no need to write code. For example, consider a collaborative platform where they can directly author, change and validate business policy decisions and share with team members.
2. Ability to grow with changing needs. Decisions are the key assets driving business, and you will need to manage them professionally. Imagine if you have a single platform that scales from your first project to an enterprise-wide program without the need for huge incremental investment.
3. Intelligent operations with robotic process automation. Bots can help you automate repetitive tasks, but you can make them much more intelligent by allowing them to make decisions, such as those involving eligibility, compliance, pricing and tax decisions. Link
