BACKGROUND AND PURPOSE When planning clinical trials, decisions regarding sample size are often based on educated guesses of parameters, which may in fact prove to be over- or under-estimates. For example, after initiation of the SPS3 study, published data indicated that the recurrent stroke rates might be lower than initially planned for the study. Failure to account for this could result in a...

Time to market or project duration has increasing significance for commercial software development. We report on a longitudinal study of a project at a leading international software organisation. The focus of this study was schedule behaviour, however, we explored a range of factors including planned versus actual progress, resource allocation and functionality delivered. In the course of the ...

Pneumococcal infection is one of the leading disease in under five children all over world. Mothers are an integral part care given to child control reoccurrence pneumococcal infection. Educating and training mothers can increase compliance with discharge plans prevent re-admissions. Planned teaching program effective strategy giving information children. The study was conducted find out effect...

As achieving high quality means the realization of customers needs, requirements engineering (RE) is the most crucial phase within software development. In the RE process not only the functional requirements but also the so-called ‘non-functional’ or ‘quality’ requirements of the planned software system have to be elicited from the customer and represented in a requirements document in order to...
