Activity. An element of work which forms the basic building block for a schedule/network. There are
different schools of thought on how detailed activity definition should be. A text I browsed recently
argued that too much detail is a waste of time and resources, a case of not being able to see the
wood for the trees. This maybe a valid point, however when my wife and I built our house, we would
not have dreamed of doing so without paying attention to detail, or being aware of what we could
expect for our money. See Task (Project Management, Planning/1.10)
Activity Calendar. An activities working pattern. An activity calendar defines the working and non-
working days applicable for an activity. For example engineers working a staff job in Europe might be
working 7,5 hours per day, 5 days a week, while construction personnel on a site in the desert might
be working 12 hours per day, 7 days a week. It is important to identify the working patterns for
different activities as these parameters will ultimately affect the schedule (Project Management,
Planning/1.10)
Activity Description. A description of the work to be performed under the activity. (Project
Management, Planning/1.10)
Activity ID. A unique reference number for the activity, required by most computerised planning
applications. In my opinion the number of characters should be kept to a bare minimum, especially if
man-hours are to be booked against them (Project Management, Planning/1.10)

Asynchronous. Transmission type (from the Greek meaning 'not at the same time'). Consider that
the character A in ASCII code is a pulse train made up of 7 bits for the code, plus 3 bits for error
checking. Under asynchronous transmission the character pulse trains are transmitted singly as they
occur (possibly at irregular periods in time), however within the pulse train all bit transmissions occur
at a fixed rate. An example which illustrates this is typing at a keyboard, not all keys are pressed
regularly, however whenever one key is pressed all the bits representing that key are transmitted at a
fixed rate. Confused? You are not alone. See Synchronous (IT, Computing/1.05)

Bandwidth. How fast data/information can be transferred over a given period of time. Measured in
hertz or bits per second. The transmission medium can be anything from a fibre optic cable, a satellite
dish, to a piece of string. The width in bandwidth does not refer to thickness as in a very fat cable (a



fibre optic fibber is very fast and thin), it refers to the width of the frequency, or the number of times
the crest of a wave passes that crest in a given time period (IT, Computing/1.05)

Baseline. A scheduling benchmark. A Project Control Baseline is the benchmark from which
subsequent schedules are measured against for deviations. The idea of benchmarking comes from the

can be measured. E.g.. schedule acceleration (Project Management, Planning/1.05)
