A data flow diagram illustrates the movement and transformation of data between externals (entities) and processes. The output from one external or process is the input to another. The data flow diagram also illustrates the temporary or permanent repositories (referred to as data stores or terminators) where data is stored within a system or an organization. The data defined should be described in a data dictionary.

 The level of abstraction is one of the key elements in the task of planning business analysis information management. It refers to the degree of detail or generality at which the business analysis information is captured and managed. Deciding on the appropriate level of abstraction is crucial as it affects how information is understood, communicated, and used by stakeholders.

Process analysis is a business analysis technique that benefits from frameworks and methodologies like Six Sigma and Lean. These methodologies are focused on improving processes by eliminating waste and reducing variation. Six Sigma uses a set of quality management methods, including statistical tools, and creates a special infrastructure within the organization (champions, Black Belts, Green Belts, etc.) who are experts in these methods. Lean, on the other hand, is centered around providing value to the customer by optimizing processes, reducing waste, and improving flow. Both methodologies are process-centric and align with the goals of process analysis, which aims to understand and document the current process and design an improved future state.

References: The connection between process analysis and methodologies such as Six Sigma and Lean is discussed in various business analysis resources, including the Business Analysis Body of Knowledge (BABOK) Guide1. The BABOK Guide is a globally recognized standard for the practice of business analysis and includes detailed descriptions of techniques used by business analysts to improve business processes2345.
