The point of sale (POS) or point of purchase (POP) is the time and place where a retail transaction is completed.

At the point of sale, the merchant would calculate the amount owed by the customer and indicate the amount, and may prepare an invoice for the customer (which may be a cash register printout), and indicate the options for the customer to make payment.

It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service.

After receiving payment, the merchant may issue a receipt for the transaction, which is usually printed, but is increasingly being dispensed with or sent electronically.

Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles.

At its core systems engineering utilizes systems thinking principles to organize this body of knowledge.

Issues such as requirements engineering, , logistics, coordination of different teams, testing and evaluation, maintainability and many other disciplines necessary for successful system development, design, implementation, and ultimate decommission become more difficult when dealing with large or complex projects.

Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects.

It overlaps technical and human-centered disciplines such as industrial engineering, mechanical engineering, manufacturing engineering, control engineering, software engineering, electrical engineering, cybernetics, organizational studies, engineering management and project management.

Systems engineering ensures that all likely aspects of a project or system are considered, and integrated into a whole.

Usability is the ease of use and learnability of a human-made object such as a tool or device.

In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use.
