Download a simple project scheduling tool for Microsoft® Excel® - by Jon Wittwer, PhD A Gantt chart is a tool for project management developed originally by Henry Gantt in the early 1900s. It is a type of bar chart that shows the start and end times for each task in a project schedule. The tasks are usually categorized using a work breakdown structure with summary tasks for the main project deliverables and sub-tasks that break the project down into a detailed and manageable task hierarchy. If you use Excel or Google Sheets, you can create this type of project schedule with almost no learning curve by downloading Vertex42's free Gantt Chart Template.

Mjellma Milioner here. Description This template contains the core functionality needed to create a simple Gantt chart easily. Each row of the worksheet represents a separate task. All you need to do is define the start date and duration of each task. • To add more tasks, you just copy and paste rows (or insert a row then press Ctrl+d to copy formulas down).

• To change the range of dates displayed in the chart area, just slide the scroll bar. • To track the status of a task, edit the% Complete column. The bars in the chart show the% complete for each task. • The vertical red line shows the current date. • To use the automatic numbering, copy the formula for the appropriate level from the bottom of the worksheet.

While planning a project, you may also want to use a or worksheet. =WORKDAY( end_date,1) Use the WORKDAY.INTL() function in Excel 2010+ to define a custom work week (days other than only Sat & Sun) The problem with only using formulas is that you can't see the dependencies between tasks when you view or print the chart.

Other Gantt chart software may show dependencies as lines connecting the bars in the gantt chart, but I've never found a simple way for Excel to do that (and the lines can get really messy). The simple approach is to list the WBS number of the Predecessor in another column, like in the critical path example above. In the CPM template and in Gantt Chart Template Pro, formulas calculate the start dates based on what you enter. If you want to try doing this on your own, here is a formula to get you started: 4. Start a Task the next day after a Predecessor task listed in another column.

=INDEX( range_of_end_dates,MATCH( predecessor_wbs, wbs_range,0)) Gantt Chart Pro uses a formula like this, but it allows up to three predecessors and it accounts for work days. Showing Critical Tasks in a Gantt Chart Some Gantt charts are designed to show the critical path and available slack or float time for each task. If every task must be done in sequence, every task is critical and there is no slack time (because if one task is delayed, it delays the entire project).

However, if some tasks can be done in parallel and have some available slack time, then the project manager may be able to free up some resources to devote to the more critical tasks. Currently, the only template I have so far that uses the Critical Path Method (CPM) algorithm to show critical tasks and available float time is the shown in the image on the left. The Gantt chart in this example shows the critical tasks in red and the available slack time in gray. The CPM algorithm requires a fully defined task dependency structure, meaning that every task must have a successor (another task that depends on it).

A simple Gantt chart may not need to have the dependencies between tasks fully defined, which is why you will see many project schedules with tasks defined only with a start and end date. Commercial Gantt Chart Software There are hundreds of software applications for creating gantt charts and project schedules. Some of the most popular are those that allow easy online collaboration such as SmartSheet.com and ProjectManager.com. And of course there's Microsoft: • - products.office.com - Although a bit pricey, this really is the ultimate software for creating gantt charts and project timelines, partly because it is widely used and you can probably find someone in your office that knows how to use it if you have questions.
