Summarizing the Benefits
One way of illustrating the benefits of PDL is to consider the
comments of users.
They give a variety of benefits as being the most important
reflecting the many ways in which PDL can be used and the variety
of methodologies it complements.
The six benefits mentioned most frequently are listed below.
All lead to the goal of greater productivity.
The management risk in software development is substantially reduced
since designs can be tested against requirements at an early stage.
Programs are better organized and more reliable since they start with
a complete, thoroughly considered design.
Software visibility is higher so estimates of progress can be more
Misunderstandings are avoided since everyone involved in a project
uses a common, unambiguous medium for communication.
This has proven especially so on projects involving multiple
contractors and on multinational projects.
Documentation in the form of PDL/81 Design Documents is
available on-line before coding starts.
Multiple designs can be economically produced and compared in cases
where the requirements are not given in full or where it is necessary
to maximize the capabilities of a system within a given budget.
