Documentation
DFD: A Data-Flow Diagram (DFD) is a graphical representation of the "flow" of data through an information system, modeling its process aspects. A DFD is often used as a preliminary step to create an overview of the system, which can later be elaborated.
Architecture diagram: A Software Architecture Design is an important step for software and application developers to describe the basic software structure by separating functional areas into layers. It depicts how a typical software system might interact with its users, external systems, data sources, and services.
Recovery documentation: A disaster recovery plan (DRP) that is documented with clear set of procedures to recover and protect a business IT infrastructure in the event of a disaster. Such a plan, ordinarily documented in written form, specifies procedures an organization is to follow in the event of a disaster.
Baseline documentation: A performance baseline is a vital part of your system documentation. A baseline should be established immediately after a new system has entered production, and should be repeated with regular intervals. That way you can see how your system performs over time and make informed decisions about when a system will have to be upgraded etc. The primary tool you use to capture a baseline on the Windows platform is Performance Monitor (or just Performance or PerfMon).
Service Manuals: Service Manuals (SM) are the manuals provided by manufacturers which cover the servicing, maintenance and repair of their products.
SLA: A Service-Level Agreement (SLA) is a contract between a service provider and its internal or external customers that describes the service, usually in measurable terms, to be furnished.
