Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Speaker: In this video, I want to answer\Nthe question 'what is a Gantt chart?'
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,[intense music]
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,The Gantt chart is arguably the most\Nwidely used project planning tool.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,In fact, it is so widely used, that for \Nsome people, it's almost the archetype
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,of what a project is all about.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,The Gantt chart is if you like the icon\Nfor project management.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,The Gantt chart was invented by\NKarol Adamiecki.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Karol Adamiecki invented his\Nharmonograph 5-10 years before
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Henry Gantt went into print, describing\Nwhat is now known as the Gannt chart.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And there is absolutely no evidence that\NI am aware of, saying whether Gannt was
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,either aware or not aware of\NAdamiecki's work.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But it does emphasize something important.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Which is, that if you want something named\Nafter you, the best thing to do is to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,write about it in english.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Because that way, Americans and British \Npeople understand what you're writing about.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,If you write about it in Russian, \Nas Adamiecki did,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,then it might not get noticed,\Nand picked up.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,That's just the way the world worked in \Nthe early 20th century.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Anyway, Henrey Gantt gives us the rules\Nthat we use for creating our Gantt chart.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,A Gantt chart plots time along the\Nhorizontal axis.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And on the vertical axis, we list all the\Ntasks that need to be done to accomplish
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,our project.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And if you've created a work break down \Nstructure, then that immediately gives
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,you your task list.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And if you don't know what a work break\Ndown structure is.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Take a look at our video, 'What is a\NWork Breakdown Structure?'
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Now, once you've created your graph, and\Nhere's something important about the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,way Gantt charts work, equal units of\Ndistance along the horizontal axis
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,represent equal units of time.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Once you've created that, then you\Nrepresent each activity by a bar.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And the length of the bar represents\Nthe duration of the task.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And the positioning of the bar represents\Nthe scheduling of the task.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, if one task follows another, then the\Nbar follows the previous bar.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And so, what we often see on our Gantt \Ncharts, are these long diagonals of
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,one activity following another in time,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,because each task is dependent on\Nthe completion of the predecessor task
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,to get started.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But then, we might have other work\Nstreams that run in parallel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,The other commonly used symbol you see on \Na Gantt chart is a simple geometrical shape
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,like a triangle or a diamond, that\Nrepresents a milestone.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And we have a video on what a\Nmilestone is as well.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, that's your basic Gantt chart.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And it's very easy to read.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And we can put a vertical line though \Nthe Gantt chart to indicate today.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So that at any point in time during our\Nproject we can read off where we should
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,be in our project, and then assess the\Nlevel of completeness.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Now of course, when you look at real \NGantt charts produced by sophisticated
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,software, they are often different sorts\Nof bars with different sorts of shading.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,There are sometimes different types of\Nmilestones.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Different shaped symbols.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,A milestone could be a decision point, or\Na completion, or a gateway review for example.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, how do you read these complicated \NGantt charts?
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Well my answer is, it's simple.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,If you don't know what the symbols mean,\Nthat's not your fault.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,It's the fault of the person who created \Nthe Gantt chart.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, when you create your Gantt charts,\Nalways be clear and put a key on the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Gantt chart explaining what the different\Nsymbols, and shading, and types of line mean.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And that way your reader will be able to\Nunderstand it very simply.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, a Gantt chart, sometimes called a\Nbar chart, represents your project plan
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,by making each task into a bar and putting\Nthose bars onto a time schedule.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Your Gantt chart is a powerful tool to \Nhelp you think through your plan,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,to articulate it, to communicate it, and \Nto monitor it during delivery.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,[intense music]
