Before prescribing actions, it's important to understand the current state and predict future outcomes. Descriptive analytics helps uncover patterns, trends, and insights from historical data, while predictive analytics utilizes statistical models and machine learning algorithms to forecast future scenarios. These preliminary stages provide a foundation for the prescriptive analytics process.

3. Formulating the Problem

Once the data is analyzed, decision-makers need to define the problem they want to solve or the objective they want to achieve. This involves identifying key performance indicators (KPIs), constraints, and potential decision options. Formulating the problem accurately is crucial for generating meaningful recommendations.

4. Mathematical Modeling and Optimization

In this stage, mathematical models and optimization algorithms are applied to find the best possible solutions. These models consider various factors, such as constraints, objectives, and decision variables, to determine the optimal course of action. Mathematical techniques, including linear programming, integer programming, and simulation, are commonly used to solve complex decision problems.

5. Decision Evaluation and Selection

After generating a set of potential solutions, decision-makers evaluate and compare the outcomes of each option. This evaluation involves assessing the impact of each decision on the desired objectives, considering trade-offs, risks, and resource constraints. The selected solution is the one that aligns best with the overall business goals and objectives.

6. Implementation and Continuous Improvement

Once a decision is made based on the prescribed action, it is implemented in real-world scenarios. Continuous monitoring and feedback loops allow decision-makers to assess the performance of their decisions and make adjustments if needed. This iterative process helps organizations improve their decision-making capabilities over time.
