In the software industry, program management is an aspect of software product management. Program management or programme management is the process of managing several related projects, often with the intention of improving an. Commonly, the problem people have is how to look for money. Although, when they already have enough money, they develop a new problem of how to use all the money. In this regard, this is where analysts and. Variables defined local to a function disappear at the end of the function scope. So when we call the function again, storage for variables is created and.
So if we want the value to be extent throughout the life of a program, we can define the local variable as . First, let me distinguish between life and scope. Life of an object determines whether the object is still in the memory (of the process) whereas scope of the object is whether can I know the variable by its name at this position. It is possible that object is live, but not visible (not in scope) but not that object is not alive but in scope (except for dynamically allocated objects where you refer object through pointers). Say for a static variable inside a function cannot be called from outside the function (because it's not in scope) but is alive and exists in memory. The next time this function is entered (within the same program) the same chunk of memory would be accessed now retaining the variables old value and no new memory is allocated this time for this variable like other variables in the function (automatic variables). So basically the variable persists throughout the program. Similarly if a static variable is defined in a global space (say at beginning of file) then this variable will be. This means such variables can be accessed from any function, any file of the program. Project Management Knowledge » Archives Difference between Project Management and Program Management. There is confusion between the term project management and program management. Although, the words seem similar there are some differences. Project management is the act of creating plans and managing resources in order to accomplish a project. A project is a scheduled undertaking for the purpose of creating a product or service. Program management, on the other hand, is the act of creating and managing multiple projects, most of the projects are usually related to one another. Project management is usually short- lived with specific time constraints while program management is an ongoing process in order to achieve the goals and objectives. The job of a project manager usually involves working on finite projects or objectives. The program manager works more often with strategy. A project management team works to identify the triple constraint of time, scope and cost of a project. Then, they plan and report on the delivery of the project. While the project is being accomplished the triple constraint is reviewed. At it’s close, the project management team will review and report on the accomplishment of the project. A program management team works to identify the mission, projects to be accomplished, and it’s close. The team provides support for the requirements of the projects. They monitor the program plan and keep track of information within the specific projects. After the completion of the project, it is reviewed and documented.
