This requirement adds to the complexity and increases the cost and effort involved in implementing TOGAF.

Furthermore, the pre-design functions in TOGAF are formalized, which can restrict the space for experimentation and modification. This formalization means that organizations using TOGAF may find it challenging to explore alternative design approaches or significantly modify their architecture. The framework emphasizes a standardized and structured approach, which may limit the flexibility and adaptability of the architecture to changing business needs.

Additionally, the approaches supported by the TOGAF literature primarily focus on organizing and structuring the architecture, rather than directly assisting in managing enterprise architecture. While TOGAF guides how to design and implement architecture, it may not offer comprehensive support for ongoing management and evolution of the architecture. This omission can be a limitation for organizations seeking a more integrated and holistic approach to enterprise architecture management.

Finally, TOGAF does not fully support the traditional approach of determining what to manufacture after a research and development (R&D) process. The framework's emphasis is on the design and implementation of the architecture, rather than the specific products or solutions to be developed. This may pose challenges for organizations that rely heavily on R&D to drive innovation and product development.

In conclusion, while the TOGAF framework offers a structured approach for enterprise architecture, it has several disadvantages. These include the framework's complexity, the need for a complete team for successful implementation, the restriction of experimentation and modification due to formalized pre-design functions, and the limited support for enterprise architecture management and the traditional R&D process. Organizations considering the adoption of TOGAF should carefully evaluate these drawbacks and assess whether they align with their specific needs and goals.

Unlike Zachman, which emphasizes different perspectives for various purposes, TOGAF prioritizes the architectural development process.

TOGAF and Zachman are two popular enterprise architecture frameworks with distinct differences in approach and focus. While TOGAF prioritizes design principles and implementation details, Zachman focuses on defining and organizing data. In terms of origin, TOGAF was created in 1997 as an alternative to Zachman, which has been around since the 1980s. The Open Group developed TOGAF, while Jack E. Zachman developed Zachman.

When it comes to models used, TOGAF employs three different models - a business model, a technical architecture model, and an application portfolio management model. On the other hand, Zachman uses a single data model with subgroups corresponding to its six perspectives. The frameworks also differ in their approach. TOGAF follows a bottom-up approach, gathering data about an organization's processes and structures to build an integrated whole. In contrast, Zachman follows a top-down approach, starting with a high-level view and working on specific details.

In handling change over time, TOGAF focuses on documenting changes for effective tracking and management, while Zachman is designed to allow for change without reworking existing structures. The usage of the frameworks also differs. TOGAF is typically used for smaller organizations or projects with fewer moving parts and stakeholders, while Zachman is more commonly used for large organizations with multiple departments and diverse needs.

The composition of the frameworks also showcases their differences. TOGAF consists of 12 principles, 4 phases, and ten roles, providing a comprehensive guide for creating strategies and plans to improve a business. On the other hand, the Zachman Framework consists of nine domains or categories of information that can be applied to any organization, regardless of industry or size.

Here are the main differences between TOGAF and Zachman:

Aspect	TOGAF	Zachman
Framework Type	Comprehensive methodology for enterprise architecture development	Taxonomy for organizing architectural artifacts
Focus	Process of developing and managing enterprise architectures	Classification of Enterprise Architecture Perspectives
