How many tasks does the product-based planning technique describe?

D.

Product-based planning is a technique used in project management to identify the required products or deliverables needed to achieve a project's objectives. It is a process that involves breaking down a project's goals into smaller, more manageable pieces to help facilitate project planning and execution.

The product-based planning technique describes four key tasks that need to be completed in order to create an effective plan for a project. These tasks are:

1. Identify the project's products: This involves identifying the products or deliverables that need to be created in order to achieve the project's objectives. These products can be physical items, such as equipment or software, or intangible items, such as reports or documents.

2. Identify the product's characteristics: Once the project's products have been identified, the next step is to define the characteristics of each product. This involves specifying what the product should do, what it should look like, and any other relevant features.

3. Identify the product's dependencies: This task involves identifying any dependencies that exist between the various products that need to be created. For example, one product may need to be completed before another product can be started.

4. Create a product flow diagram: The final task in product-based planning is to create a product flow diagram, which shows the sequence in which the various products will be created and how they relate to each other.

So, the correct answer to the question is D, four tasks are described in the product-based planning technique.
