Effort in Pro­ject Manage­ment – Defi­ni­ti­on and Meaning

Effort refers to the amount of work (mea­su­red e.g. in per­son-hours or per­son-days) or the quan­ti­ty of other resour­ces (such as mate­ri­als or bud­get) requi­red to com­ple­te a spe­ci­fic task or exe­cu­te an enti­re pro­ject. It ser­ves as a key basis for resour­ce plan­ning and cost esti­ma­ti­on. Effort is typi­cal­ly quan­ti­fied by con­side­ring both the inten­si­ty and dura­ti­on of work or resour­ce use.

Exam­p­le, Best Prac­ti­ce, and Fur­ther Information

In a soft­ware pro­ject, for exam­p­le, the esti­ma­ted effort to deve­lop a new fea­ture might be 40 per­son-hours. A pro­ven best prac­ti­ce is to esti­ma­te effort as rea­li­sti­cal­ly as pos­si­ble, based on his­to­ri­cal data from pre­vious pro­jects and expert judgment. This is in line with the esti­ma­ti­on tech­ni­ques in the PMBOK Gui­de and agi­le methods such as sto­ry points. Careful effort esti­ma­ti­on helps crea­te rea­li­stic sche­du­les and budgets.
