Bar charts
The bar chart is mainly concerned with two tasks: (a) to visualize the temporal relation of the individual processes for all project members, and (b) to allow the project manager (i.e. the manager of the project folder) to manage the dates of the individual project processes.
Process representation within the bar chart
An individual process of the project is represented by a single coloured bar. Processes with dates that have never been accepted by the project manager (e.g. processes directly after creation) are represented by a thin, lightly coloured bar, whereas processes with dates agreed, i.e. dates accepted by the project manager, are represented by a bold, dark bar. Change proposals for processes with agreed dates are represented as thin bars running within the bold bars. The same goes for delays caused by inter-process dependencies. Additionally, the process responsible for a delay is displayed in a blue font.
For simple project members, the bar chart only visualizes deadlines agreed upon and proposals for deadline shifts; project owners are provided with additional management functionality.
Dependencies
As project manager you may define dependencies between processes, i.e. you may specify that a process may only start after another process has finished.
• Select in the top menu of the bar chart.
• The
‘Dependencies’ form shows the existing dependencies for each process.
You may define a new dependency for a process by selecting another process from
the list and clicking [Add]. Existing dependencies may be removed by clicking
the 
icon.
Note that definition of a dependency may lead to a delay in dependent processes with dates agreed upon. This has to be accepted explicitly by you as project manager.
Accepting date changes
Besides date changes made necessary by the definition of new dependencies, the project members responsible for a process may also propose a date change for their process on their own (see next section). As a project manager, you have to decide on all of these date change proposals.
• Select in order to view the dates of the project as a whole and of the individual processes. The table opposes dates agreed upon and date changes suggested by the process responsible. Delays in dependent processes are indicated in italics, while the originating process is marked with an asterisk (*).
• When deciding on proposed date changes or delays due to dependencies, you may
o [Accept Dates],
o [Reject] or
o again [Change Process].
• You may also [Accept ALL changes].
With a corresponding setting, project members will be notified of these actions per email.
If the respective option is configured for your BSCW server, process owners may acknowledge the acceptance of date changes proposed.
Versions
Every [Accept Dates] action lets BSCW store the previous state of the complete project and its processes as a project version in a history archive. In order to view a table of all versions of the project,
• select in the top menu of the bar chart. Clicking the corresponding bar chart icon displays the bar chart of the version selected.
You may also delete project versions if this is configured for your BSCW server.
• Select in the top menu of the bar chart to view a table of old project versions. Check the versions you want to delete and confirm with [OK].
Settings
The project manager may change some project settings concerning the bar chart representation and the email notification about date actions.
• Select to change the preview period for project members, i.e. the future period of time for which the bar chart is displayed to ordinary project members. In the manager view, the preview period is indicated by a somewhat darker background.
• Select to change the display width of the text and the bar column in the bar chart.
• Select to activate or deactivate email notification of project members concerning acceptance, rejection or change of process dates by the project manager.
