To answer this question, you need to understand the concept of Pega guardrails and how they apply to flows in Pega.
Guardrails in Pega are a set of best practices and guidelines that ensure the quality and efficiency of application development. They help in maintaining consistency, performance, and scalability of the application.
When it comes to flows in Pega, one of the guardrails is to keep the number of shapes in a flow to a reasonable limit. Having too many shapes in a flow can make it complex and difficult to understand, maintain, and debug. It can also impact the performance of the flow.
Considering this, the correct option from the given choices is:
B. Create a subflow and Use Parallel Flows to perform functions
This option suggests breaking down the flow into smaller subflows and using parallel flows to perform functions. By doing so, you can reduce the number of shapes in the main flow and make it more manageable.
Let's go through the other options as well:
A. Create a subflow and Use Independent Flows to perform functions - This option suggests creating a subflow and using independent flows to perform functions. While this can help in organizing the flow, it does not specifically address the issue of having more than 15 shapes in a flow.
C. Use Split join shape - The split join shape is used to create parallel branches in a flow. While it can help in organizing the flow, it does not specifically address the issue of having more than 15 shapes in a flow.
D. Use Split for each shape - The split for each shape is used to iterate over a collection and perform actions for each item. While it can help in organizing the flow, it does not specifically address the issue of having more than 15 shapes in a flow.
Therefore, the correct answer is B. Create a subflow and Use Parallel Flows to perform functions. This option helps in breaking down the flow into smaller subflows and using parallel flows to perform functions, reducing the number of shapes in the main flow and adhering to the guardrail.
