Describe the strengths and limitations of project management compared with operations

Only 9% of software projects for large companies were delivered on time and within budget. For medium-sized and small companies the numbers improved to 16% and 28% respectively. (Standish Group, 1995)
The success rate for software projects is very low. Although there are a great many reasons of project failure, the analysts mark out main three messages:
1. Software development is still highly unpredictable. Only about 10% of software projects are delivered successfully within initial budget and schedule estimates.
2. Management discipline is more of a discriminator in success or failure than are technology advances.
3. The level of software scrap and reword is indicative of an immature process. (Royce, 1998)
According to Royce, the main reasons why software project got into trouble are:
Poor requirements definition
Inadequate software project management
Lack of integrated product teams
Ineffective subcontractor management
Lack of consistent attention to process
Too little attention to software architecture
Poorly defined, inadequately controlled interfaces
Software upgrades to fix hardware deficiencies
Focus on innovation rather than cost and risk
Limited or no tailoring of standards
So for many projects it’s normally never to be finished. But I think that it is possible to accomplish successfully any project, if some necessary efforts are undertaken. Only highly qualified specialist in project management should decide what kind of efforts must be undertaken.
(3) Can a measure be reliable, yet invalid Give three examples and explain.
A data source is said to be reliable if repetitions of a measurement procedures results that vary from another by less then a pre-specified amount. Validity measures the extent to which a piece of information…
Effectively managing these projects means delivering them on time and within budget. How successful an operations manager is will be strongly influenced by his or her project management skills.

A data source is said to be reliable if repetitions of a measurement procedures results that vary from another by less then a pre-specified amount. Validity measures the extent to which a piece of information actually means what we believe it to mean. A measure may be reliable but not valid. A mismarked 36-inch yardstick pretending to be a meter stick performs consistently, so it’s reliable. It does not however, match up accurately with other (standard) meter rulers, so it would be judged not valid.
Scientific School of Management. It emphasizes scientific analysis of work methods. Scientific analysis of work methods is still a valid approach to enhance efficiency and productivity, also for ergonomic analysis. It can be applicable to the modeling of the interaction of the plant’s owner with the trade union, because they are adversaries and have opposite views.
Process School of Management.
