Talk:Gantt chart

This article has been vandalized. Someone please correct. —Preceding unsigned comment added by 38.119.133.34 (talk) 17:39, 11 November 2009 (UTC)

A previous (anonymous) commenter suggested this article needed a better graphic. So I replaced the graphic and cleared this discussion page. If you have any suggestions for improving the new graphic, I'll be watching this Discussion page. --Garrybooker 05:18, 24 August 2006 (UTC)

I removed the stub flag according to stub definition, but this article might be a candidate for a cleanup flag. In particular, some of the external links appear to be beyond the mainstream. --Garrybooker 17:29, 24 August 2006 (UTC)

There might be a different understanding of terminology, but the definition of TIMENOW(simply defined) is "The date which is the starting point for the remaining work", ie the date for reschdeuling the work not performed.Janus999 10:26, 13 October 2006 (UTC)

Advantages and limitations Section Cleanup

I have added the section cleanup tag to this section as it is not easy to view an overview of this section. I suggest a cleanup splits the advantages and limitations into seperate bullet points, with a paragraph going more in depth for each if required. 144.173.6.74 (talk) 14:32, 20 January 2009 (UTC)

What about such link Gantt chart software ? Egil81 03:00, 19 December 2006 (UTC)Egil81

The list might be better merged with this article: List_of_project_management_software. I guess I don't have a strong opinion as long as advertising links aren't mixed with encyclopedic content. Good luck. --Garrybooker 05:13, 19 December 2006 (UTC)

You're still misinterpreting the external links guidelines. Georgewilliamherbert 22:11, 27 January 2007 (UTC) This is a Test Message. By N.V. Ramana

Hi, i would like put a external link to the follow direction http://www.webandmacros.com/excel-gantt-macro.htm, in this page you can see a Macro Excel development to the automatic gantt chart, the software is free, you can use this macro to the project management. I wait your answers , thanks Train78

I don't think that would be a good idea. How many webandmacros.com spam links have you added to Wikipedia so far? I count 14 this month. Please stop the self-promotion. (Requestion 04:51, 25 May 2007 (UTC))

Hi Requestion, i´m sorry to put a lot of link of my page, i put in this month 5 links (Gantt, mrp, vba, balanced scorecard and CRM), i´m new user of wikipedia, and i think that my web would be interesting about this subjects, my web don´t sell any product, and if you see my web you can find a lot of information, for example i think that could be interested one example of the MRP and if you go to my web you can find an example of the MRP and you can download a free sofwtare developed by macros excel vba to calculate the MRP, in Gantt Chart you can download in my web a free software developed with excel to calculate an automatic gantt chart to management any type if project, you can see in my web in the section of objectives, my objectives http://www.webandmacros.com/objective.htm, i wait your answer, Thanks a lot Train 78. —Preceding unsigned comment added by Train78 (talk • contribs)

Sorry Train78 but Wikipedia isn't the place for this. (Requestion 02:16, 27 May 2007 (UTC))

Any chance we could add this link? Its a NON-COMMERCIAL, open source, free software to make Gant charts on Windows. http://sourceforge.net/projects/winplanner/ —Preceding unsigned comment added by 207.119.11.101 (talk • contribs)

No thank you. It's just a download page without any other information that expands on what a Gantt chart is. I just don't see how promotional links to specific software help build on the article, be they commercial or non-commercial. Thank you for asking! Kuru ^talk 02:28, 10 September 2007 (UTC)

I would like to add the free CPMTutor site (www.cpmtutor.com). The site has useful examples of Gantt-chart and also an extension to the Gantt-chart called the Fenced-Bar Chart used in construction scheduling. --CPMTutor 22:43, 15 November 2007 (UTC)

I fell that the strengths and weakness section is rather biased towards the weaknesses - a good modern PM package based on GANTT charts can produce man different reports which address many of these so called weaknesses. And the key strength of the GANTT is showing critical path items - ths is not mentioned SimonMWatts (talk) 09:25, 10 January 2008 (UTC)

I'm just wondering why the link I added was removed. I posted a link to a fully functional web-based Gantt chart, but it was taken down. I'd just like some clarification as to why it was removed, considering it fit perfectly with the subject of the page and was not promotional. --cavejohnson2 —Preceding undated comment added 04:39, 11 February 2011 (UTC).

I wasn't the one who removed the link, but looking at it, I can see that it an example of a Gantt chart. It's a lovely Gantt chart, but linking to it doesn't substantially help readers because the only real information they gain from it is what a Gantt chart is, and the purpose of this article is to tell them just that. On the other hand, if you or someone wanted to add another image to this article illustrating different concepts in Gantt charts, that might well be appropriate if it doesn't substantially duplicate the information provided by the images already here. Zachlipton (talk) 05:01, 11 February 2011 (UTC)

Thank you for the explanation. I think the confusion stems from the fact that I didn't properly explain the link I added to the Gantt chart. It's not just a picture of a Gantt chart, it lets readers interact with and experience a Gantt chart via the web. I think that adds another element to the page, as the pictures on there currently only show what a Gantt chart looks like, not how it operates. For example, in the link I added, readers can move the colored blocks (time slots) and the chart will update the corresponding blocks automatically. I think giving readers the chance to use and play with a working Gantt chart adds a valuable element to the page. (Cavejohnson2 (talk) 02:13, 16 February 2011 (UTC))

Graphic

The graphic is on the whole good; but isn't it at an impossible stage, by the chart's own terms? It appears to show that Activity C has a finish-to-start dependency on Activity B; and Activity B is 67% complete, and Activity C 50% complete. Shouldn't this be impossible, as it shouldn't be possible to start Activity C until Activity B is complete (or that dependency wouldn't exist)? Or am I misunderstanding (it is a few years since I've done these)? TSP (talk) 21:07, 28 December 2007 (UTC)

Yes the example is wrong (dependency between B and C), maybe there should be a better graphic. - 62.127.211.2 (talk) 09:52, 30 July 2008 (UTC)

You can edit this if you like, I found the original code by accident, its in the "Drawing Gantt Charts in LATEX with TikZ, The pgfgantt Package" by Wolfgang Skala. If you use Debian (likely Ubuntu as well), with installed texlive-pictures-doc, the documentation containing the tex example is located here: /usr/share/doc/texlive-doc/latex/pgfgantt/pgfgantt.pdf , or via ctan: http://www.ctan.org/pkg/pgfgantt and its public documentation mirror: http://sunsite.informatik.rwth-aachen.de/ftp/pub/mirror/ctan/graphics/pgf/contrib/pgfgantt/pgfgantt.pdf see page 48 -87.162.14.133 (talk) 10:45, 31 August 2014 (UTC)

Is This Article Misleading?

Whilst I applaud the efforts of all those who contribute to Wikipedia I am also concerned that, in my opinion, this article is misleading and incorrect.

It is supposed to be about Gantt Charts but has very little about Gantt Charts and is mainly about Bar Charts used in scheduling that some people erroneously refer to as Gantt Charts. The example contains PERT calculations which have nothing whatsoever to do with Gantt and were not developed until around 40 years after his death.

May I refer the author and others interested in the subject to two excellent papers from Patrick Weaver; ‘Henry L Gantt, 1861 – 1919. Debunking the myths, a retrospective view of his work’. PM World Journal, Vol. I, Issue V (December 2012) and ‘Where did the Misuse of the names Gantt and PERT Originate?’. PM World Journal, Vol. II, Issue IV (April 2013).

As Weaver points out:

"Around 1984/5 Microsoft Project was launched and it used the term ‘Gantt Chart’ for its bar chart view and ‘PERT chart’ for its PDM (or CPM) network diagram. Both terms are ‘wrong’ form a purist perspective, but the increase in the usage of both terms seems to correlate with the rise to dominance of Microsoft Project over many competing PC scheduling tools."

and furthermore

"In the meantime, we should all try to use the correct name for charts, diagrams and processes. It may come as a surprise to some, but the name we call things matters because it communicates what we are talking about to our audience. The alternative was effectively described by Robert McCloskey, a US State Department Spokesman several years ago ‘I know that you believe that you understood what you think I said, but I am not sure you realise that what you heard is not what I meant!’ Effective communication needs a mutual understanding of the terms used, and this is helped if the terms are consistently used for their correct purpose."

Adamiecki

The reference given to credit this chart to Adamiecki actually says "This type of chart is very different to the charts developed by Henry Gantt". I think it is fair enough to make a comment that a similar approach to a similar problem had resulted in another type of scheduling chart by Adamiecki, but this should not be in the lead.
