Duration in hours #225

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. When adding a task, it is assumed that the duration is one.  It isn't 
possible to reduce this below 1.  The measurement is in days - what if there is 
a half day or 3 hour task?

It would be good to be able to indicate 1hr, 3hrs or 7hrs or 1 day.  I guess 
Hours, Days, Months would be the desired units.

What version of the product are you using? On what operating system?
Using 2.0.10 on Windows 7.

it's possible for a 2.5 on windows 7?

Thank's,

If it was possible it would have been one of the major highlights of GP 2.5.

I'm new here and I don't understand Issue 225. Does Accepted mean there is a 
commitment to implement Durations of hours, days, and months? And is it a 
medium priority task which nobody has committed to?

I'm running GanttProject on an iMac and could really use this feature.

Thanks for any clarification.

Accepted means that need is acknowledged. We normally don't use priority field, 
it is "medium" in all issues.

Original comment by dbarashev on 1 Mar 2012 at 9:16

GoogleCodeExporter commented 9 years ago 
Does acknowledged mean that the feature will be added eventually?

Original comment by thompson...@sbcglobal.net on 1 Mar 2012 at 9:20

GoogleCodeExporter commented 9 years ago 
We'll be working on this particular issue, but in general acknowledged means 
"yes, we understand the request in general, and if someone is willing to work 
on it, we are opened for discussion". No promises.

I hope you know that GanttProject is not a commercial product. We work on it 
when we have spare time. That's normally not more than 1 hour per day.

Thank your very much. Didn't mean to sound pushy...just trying to understand 
your language. GanttProject is a super product!! I deeply appreciate all you 
guys have done. If I could code...I'd offer to work on the feature.

Sorry for starring this twice :(

This is a fantastic piece of software, and I appreciate that you've produced it.

Unfortunately, as a construction professional for whom most tasks are measured 
in hours, with task Duration limited to Days, it is essentially unusable for my 
profession.

For me the app is absolutely not usable at all with durations bigger tha 1 day.

I don't understand why this is not included already. This is a need !

Original comment by leger.fr...@gmail.com on 8 Apr 2013 at 9:58

GoogleCodeExporter commented 9 years ago 
To all who complain why things do not advance.

1. This is a free product, build by people in their free time. Give them some 
slack !!

2. If you want to push for some features, I might help to donate and ask the 
dev team to develop 'your' feature with priority (if possible). Then the devs 
will feel more motivated and appriciated. Then is is worthy for example to take 
the day off at the normal job to work on this.

A little bit of code bounty sounds nice, i could donate some bitcoins for this

Just want to let you know guys that this feature touches a lot of code and 
requires a few weeks of skilled development. It is not a matter of just one day.

Original comment by dbarashev on 8 Apr 2013 at 8:44

GoogleCodeExporter commented 9 years ago 
Ok, guys, do the math:

2 weeks of dev, dayrate of 300 dollar (to keep is reasonable cheap)
Gives the total sum of 3000 dollar.

To all those that were so interested in this feature. Are you willing to bounce 
for a part of that money ?

I just put down 42 dollars myself, as Dmitry can confirm. This is a feature I'm 
willing to pay for! And though I don't know much about Java (just 
ECMAScript)... I'm willing to work in between projects (as a chemical engineer) 
and planning a wedding with my future wife.

I really like the Gantt Project, but I strongly believe that we all need to 
pitch in to make it even better.

I would like to have an option to get rid of the calendar use arbitrary time 
duration, for example, decimal seconds starting at time=0.  This would be very 
helpful for creating timing diagrams for automated systems.  If you're going to 
do hours, could you add options for other time units as well?  

Great software, very easy to use!

I too would like to have hours and minutes so that a plan that leads to a 
single (or multiple-) day event with a minute-by-minute schedule can be planned 
within the day.
I wouldn't mind if it was a separate project page. I could do long-range 
planning with the current set-up, then  switch to the Day-Of page to plan and 
examine the "minutia", so to speak.
An example of one that does scale from months, weeks and days to hours and (5) 
minutes is http://www.tomsplanner.com 
But it does not have a resource loading view like GanttPoject or OpenProj.

This app is essentially useless without this. In fact, it'll be much more 
usable if it had hours as duration, and no days at all.

Love the app, but can't use it.

Please implement the "duration in hours" feature - it is the major requirement!!

Also cannot use it without at least hours.....agree with #38....just hours, no 
days would be more useful if that cuts down on the development time....Would 
contribute $40 to get the feature.   It looks to me like if you sent out a 
request for funding to your community, it is likely that a high percentage 
would donate a bit to get the feature.

Original comment by darryl...@gmail.com on 4 Jul 2014 at 7:05

I understand that is an open source project, but the impossibility of set a 
duration less  then one day doesn't make sense.

This is a major missing component... add this and the ability to track resource

this sw is awesome....

Original comment by michaelr...@gmail.com on 30 Aug 2014 at 7:45

Duration in a wide range of units would be helpful.  I'm looking at cycle time 
optimization and dependencies where 1 second (or even 1 millisecond) increments 
would be perfect!

Original comment by spartacu...@gmail.com on 29 Sep 2014 at 7:41

GoogleCodeExporter commented 9 years ago 
Agree with the June 5 comment. Would be better to just have hours instead of 
days if it can't have both. Then you could set 24hrs for a day.

This is the ONLY feature keeping me from recommending it to our company. Great, 
great software, but fairly impractical if you can't divide to anything less 
than 24 hr units. Seems like a fundamental requirement for a project management 
software.

Also, with the number of people requesting it, agree that a request for funding 
to get this feature would likely bring you more resources and ultimately bring 
back those users who want to use this software but are not able to as it is.

+1 on hours. I'd like to see this in hours. I'd like to utilize Gantt chart's 
for Backup & Recovery projects. 

I'd like to see this be able to pull data from a SQL database. For instance, 
pull run-times (Typically in hours) from a table and present run-time's in 
Gantt form. This way I can tell which servers are taking the longest, and allow 
me to visualize where I should be placing servers in the back up. 

Thanks, 
Justin

Must needed feature. I end up with resources with 800% usage per day because 
multiple tasks are completed a day often in 1-3 hours.

> 1. This is a free product, build by people in their free time.

This is what I really do not understand. People spend tons of their time 
implementing software like this, and leave out key features which renders the 
software useless for a significant portion of their target audience. What is 
the point?

1 day per task as a minimum -- I mean, really???
