The design of a Business Impact Analysis (BIA) questionnaire is critical for gathering accurate, consistent, and relevant data. The questionnaire must be designed to be easily understood and completed by business process owners. Key design factors include: ensuring the information requested is concise to maintain focus (A); using a clear and logical layout to guide the respondent (B); selecting appropriate types of questions (e.g., quantitative, qualitative) to elicit specific data on impacts and dependencies (C); and defining the required level of detail to establish recovery objectives without being overly burdensome (D). These factors collectively ensure the quality and utility of the data collected for the BIA.

E. Image and Pictures: While images can be used for clarification, they are not a primary or standard design factor for BIA questionnaires, which focus on textual and numerical data about processes.

F. Virtualization: Virtualization is a technology concept that may be a subject of the BIA (e.g., a resource to be analyzed), not a principle for designing the questionnaire itself.

This section details the information that needs to be collected for a BIA, such as impacts over time and dependencies. The successful collection of this data relies on well-structured data collection methods like questionnaires, which implicitly requires attention to detail (D), question types (C), and clarity (A, B).

This academic case study discusses the BIA process, including the use of questionnaires for data collection. The methodology highlights the importance of structuring the questionnaire to gather specific details on critical processes and impact levels, supporting the need for a defined level of detail (D) and appropriate question types (C).

In Chapter 5, "Business Impact Analysis," the authors discuss data collection techniques. They emphasize that questionnaires must be carefully designed for clarity, ease of use, and the ability to capture both quantitative and qualitative data, which directly relates to conciseness (A), layout (B), and question types (C).
