30% of applications can be generated or supplied directly from business

Martin menar att mindre företag i bästa fall har råd med någon systemerare som gör
bildskärmslayouter eller genererar program med hjälp av programgenerator. Det
mellanstora företaget har det sämre, för där vill man göra allt själv och använda traditionella
metoder, för att "pioneers often get killed". Följande stycke är citat från
sidorna 7 och 8 i Martin:
"To achieve the degree of end-user participation in computing required by
the stratetgy in Fig 1.2 (punkterna för det stora företaget ovan) is a major
change. It requires "user-friendly, nonthreatening" software and application
dialogues. It requires a massive number of users to be trained. It requires
a change in the role of the systems analyst who will increasingly assume
a consultant role, guiding and teaching the users, showing them the
possibilities, acting as salespersons of new methods, solving the users'
problems and generally handholding. It will require an understanding by
senior management that they must motivate the users to participate, putting
statements in their management-by-objectives forms, which instruct
and encourage users at all levels to apply the new DP tools.
An opinion commonly hold by DP professionals and by computer manufacturers
and development staff is that end users are not mental equipped
to participate in the DP creation process… Many users feel that they are
too busy or have something more important to do. Many are frightened of
terminals and do not use them because they might appear foolish in front
of their colleagues. Some have a slightly arrogant attitude and will not
learn, in the same way that a manager will not learn to type. Users often
need to be encouraged or instructed from above to get over the hurdle
which prevent them making better use of today's computers. ...
There are now many examples of end users participating in the DP process
with results much better than those that would have come from DP proffesionals,
because the end users know the subtleties of what they want to accomplish.
To make this happen on a large scale needs software and tools
quite different from those which the traditional programmer uses. Those
facilities now exist and will rapidly improve. ..."
Martin tar här upp viktiga förutsättningasr, nämligen utbildning av användare och
behovet av lämpliga redskap. Han hävdar också att användare generellt sett är bättre
systemutvecklare än dataexperter eftersom de har bättre kunskap om verksamheten.
