In place of the punched card or tape we now have the computer keyboard and video screen which enable the planner to input the data direct into the computer without filling in input sheets and relying on a punch operator. The information is taken straight from the network and displayed on the video screen as it is typed in. In this way the data can be checked or modified almost instantaneously. Provided sufficient information has been entered trial runs and checks can be carried out at any stage to test the effects and changes envisaged. Modern planning programs or Project Management systems as they are often called enable the data to be inputted in a random manner to suit the operator provided of course that the relationship between the node numbers or activity numbers and duration remains the same. There are some programs which enable the network to be produced graphically on the screen as the information - especially the logic sequence - is entered. This it is claimed eliminates the need to draw the network manually. Whether this practice is as beneficial as suggested is very doubtful. For a start the number of activities which can be viewed simultaneously on a standard video screen is very limited and the scroll facility which enables larger networks to be accommodated does not enable an overall view to be obtained at a glance. The greatest drawback of this practice however is the removal from the network planning process of the team spirit which is engendered when a number of specialists sit down with the planner round a conference table to hammer out the basic shape of the network see Chapter 20 . Most problems have more than one solution and the discussions and suggestions both in terms of network logic and durations are invaluable when drafting the first programs. These meetings are in effect a brainstorming session at which the ideas
