There are many different roles in addressing a full business solution. Some of these will probably form the core full-time project team. Others may be part-time specialists, and others might be representatives of various groups interested in the project. As well as identifying the type of person, it is often necessary to give thought to the level of capability or power. If we need someone who can take a business decision we must identify the right person. If we need someone to do routine work, we should not waste the time of a more expensive resource.
At one time it was
thought that bacteria
and other procaryotes were essentially "bags of enzymes" with no
development of the electron microscope in the 1950s revealed the
distinct anatomical features of bacteria and confirmed the suspicion
that they lacked
a nuclear membrane. Procaryotes are cells of
simple construction, especially if compared to eucaryotes. Whereas
cells have a preponderance of organelles with separate cellular
procaryotes carry out all cellular functions as individual units.
Once a paradigm shift has taken place, the textbooks are rewritten. Often the history of science too is rewritten, being presented as an inevitable process leading up to the current, established framework of thought. There is a prevalent belief that all hitherto-unexplained phenomena will in due course be accounted for in terms of this established framework. Kuhn states that scientists spend most (if not all) of their careers in a process of puzzle-solving. Their puzzle-solving is pursued with great tenacity, because the previous successes of the established paradigm tend to generate great confidence that the approach being taken guarantees that a solution to the puzzle exists, even though it may be very hard to find. Kuhn calls this process normal science .
