? What is “systems analysis”? What is “systems architecture”? Problem Solving Technique Decomposition Business Process Modeling What is the problem? What is the solution?
6
Systems Analysis "Systems analysis is a problem solving technique that decomposes a system into its component pieces for the purpose of the studying how well those component parts work and interact to accomplish their purpose" - Wikipedia [ [ "the process of studying a procedure or business in order to identify its goals and purposes and create systems and procedures that will achieve them in an efficient way“ – Merriam-Webster Dictionary So what does a systems analyst do?
7
Systems Architecture Systems Architecture is a generic discipline to handle objects (existing or to be created) called "systems", in a way that supports reasoning about the structural properties of these objects. Systems Architecture is a response to the conceptual and practical difficulties of the description and the design of complex systems. – Boris Golden Once a systems analyst understands the business problem, they architect a solution

Swim Lane Diagram A type of process flow diagram that features divisions or "lanes." Each lane is assigned an actor (which may be an individual, department, division, group, machine, entity, and so on), or even a phase or stage in a process, that is responsible for the activity or work described in the lane. 14 Source: http://www.modernanalyst.com/Resources/Articles/tabid/115/ID/1868/An-Introduction-to-Swimlane-Diagrams.aspx
