According to TOGAF, in which sequence should Application Architecture and Data Architecture be developed in Phase C?

Question

Options

• AApplication Architecture should be developed first, then Data Architecture
• BApplication Architecture should be developed concurrently with Data Architecture
• CData Architecture should be developed first, then Application Architecture
• DApplication Architecture and Data Architecture may be developed in either sequence

• A
  4% (1)
• D
  96% (22)

Explanation

TOGAF explicitly states that the order is flexible. Phase C covers the Information Systems Architecture domain, which encompasses both Data Architecture and Application Architecture. TOGAF provides guidance for each in separate steps but notes that organizations may choose to develop Data Architecture first (if data is the primary driver), Application Architecture first (if application functionality is the priority), or develop both concurrently. This pragmatic flexibility is by design, as different organizations have different priorities. A common misconception is that TOGAF mandates a fixed order; it does not.
