Architectural drivers are formally defined as the set of requirements that have significant influence over your architecture. 4 Architecture Design Considerations 9 4.1 Variabilities and Commonalities 9 4.2 Software Templates and System Infrastructure 10 4.3 Architectural Drivers 11 4.4 Requirements, Quality Attributes, Functionality and Architectural Styles 12 5 The ABD Method Within the Life Cycle 15 5.1 Abstract Functional Requirements 16 5.2 Use Cases 16 The enterprise architect needs to be aware of these change requirements and considers this an essential part of constant renewal of the architecture. This section defines the inputs to Phase H. The level of detail addressed in Phase H will depend on the scope and goals of the overall architecture effort.

A change order is an official request for additional time and funds in order to complete revised contractual obligations. be a simplification change handled via change management techniques, The Foundation Architecture needs to be re-aligned with the business strategy, Substantial change is required to components and guidelines for use in deployment of the architecture, Significant standards used in the product architecture are changed which have significant end-user impact; e.g., regulatory Capacity measurement and recommendations for planning is a key aspect of this phase. It is already becoming clear that taken together, inevitable architecture’s elements represent a sea change across the IT enablement layer—a modern architecture up, down, and across the stack that can deliver immediate efficiency gains while simultaneously laying a foundation for agility, innovation, and growth. The architectural style, also called as architectural pattern, is a set of principles which shapes an application. the architecture above the physical layer, but it will change the Baseline Description of the Technology Architecture; this would When changes are identified, change management will determine whether to formally initiate a new architecture evolution cycle. Phase H also provides for changes to the framework and principles set up in the Preliminary Phase. By interacting with intra- and extra-program stakeholders, including … The scheme that I found to work the best is to divide drivers up by the intended operating system. Your application borrows a connection from the pool, uses it, then returns it to the pool by closing it. a project in a Transition Architecture will resolve the issue. This chapter looks at establishing procedures for managing change to the new architecture.

Drivers are the events, conditions or circumstances that motivate an enterprise to change some aspect of its goals and consequently its objectives, and potentially business activities or technical solutions. There is usually an existing infrastructure and business which is already providing value. changes. Often, multiple models and non-model artifacts are generated to capture and track the concerns of all stakeholders. the process by which that will happen, The circumstances under which the architecture development cycle will be initiated again to develop a new architecture, Strategic, top-down directed change to enhance or create new capability (capital), Bottom-up changes to correct or enhance capability (operations and maintenance) for infrastructure under operations If the performance management and reporting has been built into the work products through previous phases, then this phase is about ensuring the effectiveness of these. The upcoming release of Windows CE 6.0 ships with a redesigned kernel, memory model and device driver architecture, Juggs Ravalia is a Program Manager on the Windows CE drivers … Monitoring business growth and decline is a critical aspect of this phase.
