Troubleshooting: Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state. In general, troubleshooting is the identification or diagnosis of "trouble" in the management flow of a system caused by a failure of some kind. The problem is initially described as symptoms of malfunction, and troubleshooting is the process of determining and remedying the causes of these symptoms. A system can be described in terms of its expected, desired or intended behavior (usually, for artificial systems, its purpose). Events or inputs to the system are expected to generate specific results or outputs. (For example, selecting the "print" option from various computer applications is intended to result in a hardcopy emerging from some specific device). Any unexpected or undesirable behavior is a symptom. Troubleshooting is the process of isolating the specific cause or causes of the symptom. Frequently the symptom is a failure of the product or process to produce any results. (Nothing was printed, for example). Corrective action can then be taken to prevent further failures of a similar kind.

Property Management: Property management is the operation, control, and oversight of real estate management indicates a need to be cared for, monitored and accountability given for its useful life and condition. This is much akin to the role of management in any business. Property management is also the management of personal property, equipment, tooling, and physical capital assets that are acquired and used to build, repair, and maintain end item deliverables. Property management involves the processes, systems, and manpower required to manage the life cycle of all acquired property as defined above including acquisition, control, accountability, responsibility, maintenance, utilization, and disposition. For example, an owner of a single family may engage the services of a property management company. The company will then advertise the rental property, handle tenant inquiries, screen applicants, select suitable candidates, draw up a lease agreement, conduct a move in inspection, move the tenant(s) into the property and collect rental income. The company will then coordinate any maintenance issues, supply the owner(s) with financial statements and any relevant information regarding the property etc.
