Basic Concepts > Standard Objects

There are some essential objects which need to be considered for successful PackBench utilization:

•Projects: A project is a logical unit which groups a dedicated set of workflows. A bench project may resemble a real project, such as an operating system migration project or typical workflows required for servicing a specific customer, business unit, or packaging team. Projects have no other function or technical dependencies. To learn more about projects in PackBench read the chapter Configuring Projects.

•Workflows: Workflows are templates that describe ordered sequences of tasks required for performing specific tasks. Each workflow template belongs to a specific project. Within the PackBench each workflow has a name and may optionally be equipped with a description and a help file. When a workflow is created, the user defines a set of variables (see below), which are used to save information that is either needed to perform the tasks, or are derived as results from task execution. Workflow tasks may either be executed in a strictly guided sequence from A to Z or in a free mode that allows arbitrary execution. Users may instance as many runs from each workflow template as required for the packaging factory operation. To learn more about workflows in PackBench read the chapter Configuring Workflows.

•Runs: When a packager starts working on a new task, he browses the project repository of workflow templates and instances a run from the template that fits the current order. Thus, a run is a copy of a specific workflow which is filled with information and executed step by step. Whilst a template is a generic description of what to do in which order, the runs execute and document the actual activity for a single packaging order. Runs are usually executed by one member of a packaging team, but may as well be taken over, for example when team organization requires a stand-in. Each step of a run may be due or done, whilst the run itself may have an overall status (e. g. open, complete, on hold), which may be assigned by the packager as he works his way through the single tasks. To learn more about runs in PackBench read the chapter Workflow Runs.

•Variables: Variables are required to be able to move from a general and more or less abstract workflow template to the actual instance values for a specific packaging task. Variables are defined as part of the workflow and filled with values during run executions. There are different types of variables differing according to their information content: free text or numeric input, checkbox (single or list), date selector, combobox, and file or folder path selector.
Some of the variable types may be defined with optional input validation settings. Workflow tasks may make use of logic execution elements, so called tools (see below). These tools may utilize and modify variable values of a workflow run by referencing their specific variable name. There are default variables available for every workflow, e. g. PackageName, Type, Vendor. To learn more about variables in PackBench read the chapter Editing Workflows.

•Tools: PackBench intends to especially speed-up packaging related tasks. To do so, it does not only orchestrate tasks and documents their execution status, but at the same time improves their execution by integrating specialized tools. A tool can be any kind of executable, such as an external application or script. When a tool is configured for usage within the PackBench, it may be parameterized with values from variables, which are defined per workflow template. Typical parameters would be the resource type and location, applicable templates, and the like. Tools help to make sure complex tasks are performed exactly as required, even when they are performed by less experienced packagers. Tools multiply and preserve valuable packaging know-how, and make it available for each job a packaging factory team takes over. Tools therefore improve the overall quality of the factory results as well. To learn more about tools in PackBench read the chapter Configuring Tools.
