The set of jobs that revolve around creating and submitting programs that work for people in various industries is called application life cycle management. Software can be sophisticated programs that control every aspect of a companies financial transactions, or it can be a simple program that fills out orders. These roles can all be filled by different programs. The lifecycle management for an application begins with the component development and continues on to system development. The final steps are to perform quality assurance on the system in addition to developing the maintenance processes for the software system. Each of these many steps is considered to be a specialized discipline in it of itself and requires a skilled individual. Application lifecycle management is a key tool for many reasons. A business in sales cannot function without the manager that runs the business. If you try to run a function without a software system in the background monitoring and managing it, you will be setting yourself up for failure. This system shows a manager his sales team's strengths and weaknesses. It also allows him to pass that information on to his manager's and the rest of the company. To create this kind of system, you first determine what the system should do. These requirements will later form the basis of an agreement between both the system creators and the people purchasing these systems. As systems become more and more advanced, it takes longer to plan out what will be required. Once actual development is underway and planning is over, it takes a lot of time and money to start over from square one. The system needs to be competitive. Planning and development are important, but quality assurance and testing are necessary to ensure that the system will have an edge. If a system is full of flashy additions that make it complex, it's still useless if it can perform with efficiency on a reliable basis. Each piece of software is carefully tested by teams of developers who check each portion to make sure it will fulfill it's requirements. The last concept to discuss is the idea of system maintainability. Over time, the tech world has and will continue to experience progress which leads to hardware and software products becoming obsolete. You certainly can't expect a ten year old computer to be able to use the latest software or peripherals. To take best advantage of the latest gear, one must plan to invest in developing or replacing a computer as time goes by. Application lifecycle management could involve a complex system used to control the payroll and other financial functions, or a simple order tracking system for a branch office. It all starts with development of the components and continues to systems and processes for quality assurance and. Each of these steps is a discipline in itself. A business or manager without a software system to manage functions would be unthinkable in today's technically charged world. quality assurance or system testing is ever so important to have the system deliver the competitive edge. Last but not the least is system maintainability.
