OG0-092: TOGAF 9 Part 2 Exam

You are acting as the Lead Architect for a convenience-store chain operating as a franchise, with more than 5000 retail outlets across the Asia-Pacific region. The stores operate 24 hours a day and 7 days a week, relying on point-of-sale technology to manage inventory.

Stores place all orders on-line. The back-office systems gather real-time data to support ordering and product-selection decisions, including tailoring product assortments using sales history, customer demographics, and the following day's weather forecast. In many cases, several stores are located in neighboring areas. This strategy reduces the cost of distribution to each store and enables multiple deliveries per day.

An Enterprise Architecture practice is in place within the company, jointly sponsored by the CEO and CIO. They have chosen to adopt TOGAF 9 within the practice, and the first project is to restructure the Enterprise Architecture so it can better accommodate the company's changing strategies and respond more effectively to changes in economic and technical environments.

The CIO has stated that the following issues must be addressed in the restructuring:

• The systems must be capable of withstanding any unforeseen disruptions that could affect day-to-day operations. This is highly critical to ensuring high levels of customer satisfaction and maintaining and growing revenue.
• Dependencies among the application components, the application platform, and technology infrastructure should be minimal and clearly defined. This will support scalability and make enhancement of the service offerings easier.
• The company is adopting the ARTS Operational Data Model and Data Warehouse Model from the National Retail Federation. This will address previous problems with data quality and inconsistent data.
• To remain competitive, new products and promotions must undergo market trials and, if successful, be deployed throughout the retail chain. Information systems must be able to manage changes and updates without undue delays.

[Note: Assume that the company has adopted the example set of principles listed and defined in TOGAF, Section 23.6. You may need to refer to Chapter 23 of the reference text to answer this question.]

You have been asked to identify the architecture principles most relevant to the current situation.

Based on TOGAF, which of the following is the best answer? [Note: The ordering of the principles listed in each answer is not significant.]
