Operations management help essay on: Gantt charts in operations

There are various organisations that make use of Gantt charts in the operations. One of the organisations is IBM. The company uses Gantt charts to show how tasks and resources are allocated. IBM makes use of Gantt charts for the proper management of the flow of work in the rational Software division. Gantt charts are used by the company for tracking changes and automation of processes (GanttChart for ClearQuest  1.1. 2012). Gantt charts are helpful in controlling the software development cycle of the company. Gantt charts are used for ClearQuest for managing the capabilities of project. With the use of Gantt charts, it becomes possible for the company to manage the complicated and hierarchy of activities. This has been helpful in providing project management functions, and reduces the responsibilities of project managers to manage routine operations of the project.  Thus, IBM uses Gantt charts for having a flexible solution, so that any changes in the tasks can be met with proper coordination of all the fields.

The PERT chart was developed for being used in US Navy projects, for managing the project planning of their projects. They used this technique to manage the completion time of their projects. The use of PERT technique by Navy was to define a realistic timeline within which the project can be completed (Stallsworth 2009). PERT provided a simpler way to the company for managing their complicated projects.

Limitations of these techniques

Although Gantt charts have been used as an effective tool in operations of industries, yet there are certain limitations of using this tool. These limitations are discussed below:

• In case any change is required to be made in the schedule, the entire Gantt chart will have to be drawn again (Lock 2007).

• The use of this tool can be complicated, when applied in the application of typical projects. The reason is the use of large number of tasks that will be involved in completing a project.

• There is a problem of regular updating these charts, due to the new projects and its requirements.

• The use of Gant can be a time consuming task, as these charts can be viewed only in segments.

• A flaw of using PERT charts is its assumption that a delay that affects one item has no effect on the delay taking place in another item.

• Gantt charts are inefficient in displaying the types of resources that are used in the project.

• PERT chart are inefficient in identifying the time taken to complete the project.

• Variations in the processing times of the operations of the work centres are not displayed through Gantt Charts.

• Companies using PERT face the difficulty of defining each and activity involved in the project.

• PERT are the network charts that may require enormous space to be represented.

• Gantt charts are inefficient in listing the number of dependencies between operations.

• The various possibilities of scheduling cannot be displayed in the same Gantt charts.

• There also occurs the problem of verifying and calculating the dependencies of variables (Smith 2001).
