Work System Life Cycle Model
The dynamic view of a work system starts with the work system life cycle (WSLC) model, which shows how a work system may evolve through multiple iterations of four phases: operation and maintenance, initiation, development, and implementation. The names of the phases were chosen to describe both computerized and non-computerized systems, and to apply regardless of whether application software is acquired, built from scratch, or not used at all. The terms development and implementation have business-oriented meanings that are consistent with Markus and Mao’s (2004) distinction between system development and system implementation.
This model encompasses both planned and unplanned change. Planned change occurs through a full iteration encompassing the four phases, i.e., starting with an operation and maintenance phase, flowing through initiation, development, and implementation, and arriving at a new operation and maintenance phase. Unplanned change occurs through fixes, adaptations, and experimentation that can occur within any phase. The phases include the following activities:

Famous quotes containing the words work, system, life, cycle and/or model:
“But a man must keep an eye on his servants, if he would not have them rule him. Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world. But it is found that the machine unmans the user. What he gains in making cloth, he loses in general power.”
—Ralph Waldo Emerson (1803–1882)
“You and I ... are convinced of the fact that if our Government in Washington and in a majority of the States should revert to the control of those who frankly put property ahead of human beings instead of working for human beings under a system of government which recognizes property, the nation as a whole would again be in a bad situation.”
—Franklin D. Roosevelt (1882–1945)
“The genuine artist is never “true to life.” He sees what is real, but not as we are normally aware of it. We do not go storming through life like actors in a play. Art is never real life.”
—Wallace Stevens (1879–1955)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
