1) The three key disciplines used to effectively construct a Foundation of Execution are: Operating Model
This dictates the level of business process integration and standardization for delivering goods and services to customers. Process Integration depicts the extent to which business units share data and enables end-to-end and a single interface for the customer The Operating Model involves a commitment to how the company will operate

Enterprise Architecture
This is the organizing logic for business processes and IT infrastructure which reflects the integration and standardization requirements of the company’s operating model. The Enterprise Architecture provides a long term view of a company’s process, systems, and technologies in order to build long term sustainable capabilities. IT Engagement Model

The IT Engagement Model is the governance mechanism that ensures business and IT projects achieve both local and companywide objectives. This Model influences projects decisions ensuring that individual solutions are designed according to the enterprise architecture. The IT Engagement Model provides alignment between IT and the business objectives of projects. 2) The Enterprise Architecture communicates the high-level business process and IT requirements of a company’s operating model. This differs from IT Architecture to the degree of granularity that is presented. Enterprise Architecture does not provide the necessary details to map out technical or process design requirements. The IT Architecture developed by the IT unit is a more detailed architecture of applications, data and information, and technology. IT Architecture when developed with a clear understanding of the Enterprise Architecture provides long-term value because they provide the long-term vision for immediate solutions.

3) The current market trends and speed at which technology and the competitive landscape is constantly changes make it difficult for companies to be able to adapt and survive.

The pressure that agility places the foundation of execution Role of business discipline in current national and political environments Role of costs in absence of foundation of execution

Business agility increasingly depends on a Foundation of Execution. Implementing standardize, digitized processes results in simpler technology environments, lower cost operations and greater agility.

4) An operating model has two dimensions: business process standardization and integration. Companies are characterized into the following Operating Models: Diversification: Low Standardization, Low Integration

Coordination: Low Standardization, High Integration
Replication: High Standardization, Low Integration
Unification: High Standardization, High Integration
Examples:
