Study Notes
Structure of Modular Programs and Evolution of Software Engineering
- Structure charts (SCs) were created to organize modular programs effectively.
- Manual enterprise processes varied by how orders were received (e.g., mail, phone).
- Automated processes revealed multiple versions of order entry, leading to maintenance challenges.
- Program maintenance chaos resulted from redundant data stores and disorganized data maintenance.
- Redundant staffing and training lead to increased costs and decreased profitability.
Development of Relational Database Technology
- Late 1960s to 1970s saw the emergence of relational database technology, foundational for current systems.
- IBM DB2 and Oracle RDBMS were among the first relational database management systems (RDBMS).
- Mid-1970s focused on data modeling methods aimed at eliminating redundant data using normalization.
Object-Oriented Methods and Enterprise Architecture Planning
- The 1980s introduced object-oriented (O-O) development and Unified Modeling Language (UML), enhancing code reusability.
- Enterprise Architecture Planning (EAP) focuses on analyzing data, applications, and technology across an enterprise.
- FEAF (Federal Enterprise Architecture Framework) utilizes Dr. Steven Spewak's EAP to define architecture planning.
Enterprise Architecture Plan (EAP) Layers
- Layer 1: Establish a work plan emphasizing management commitment and methodology selection.
- Layer 2: Analyze the current architecture and systems technology to create a migration plan.
- Layer 3: Define a vision with data, applications, and technology architectures necessary for business support.
- Layer 4: Formulate an implementation plan outlining sequence, schedule, and cost-benefit analysis for resource allocation.
FEAF and the Zachman Framework
- FEAF reinterprets the Zachman framework's first three columns (What, How, Where) to align data, applications, and technology architecture.
- Premise of FEAF is to ensure compliance with resource approvals from Office of Management and Budget (OMB).
Performance Reference Model (PRM) and Business Reference Model (BRM)
- PRM provides a performance measurement framework to manage business strategies and measure progress.
- BRM offers a function-driven framework detailing enterprise operations but may lack comprehensive EA guidance without additional methods.
On-Demand Computing and Virtualization
- On-demand computing delivers resources as needed, allowing enterprises to scale operations efficiently, particularly during peak demands.
- Virtualization involves creating an abstraction over hardware, allowing multiple virtual machines (VMs) to function on a single physical machine.
- Rapid delivery methods in enterprise architecture facilitate business transformation by adapting to future needs rather than outdated processes.
Drucker’s Questions and Strategy Analysis
- A solid mission statement answers Drucker's defining questions about business identity, target customers, required products/services, value perception, and future aspirations.
- Strategy analysis includes understanding the mission, identifying key business areas, defining objectives, recognizing opportunities/problems, and establishing KPIs.
