How can tempo gantt and Jira to show gantt with  just Assignee, Original estimate, project start date ? start and end dates to be calculated based on original estimate and display on the timeline continously.

Eg; if there are 4 tasks assigned to a user and each takes 2 days, and project start date is Dec 4th, on Tempo gantt visually i have to see 8 working days of (gantt) bar

Hello @Harini Kantheti 

If you have the following:

- 4 tasks assigned to the same user;
- each task has Original estimate set to 2 days;
- do specific Start & Finish dates are set for their work in Jira.

And if you want to see the 4 tasks scheduled one after the other on the chart's timeline, then you can do it the following way:

1. Use the default settings of the Gantt chart. By default, work estimates are taken from the Time tracking section in Jira, so if only Original estimate is defined - it will be used for scheduling.
2. Select the Assignee field as the resource Attribute in the Resources tab.
3. Define the Project Start day of the chart.

As a result, you should see all 4 tasks starting and finishing within the same 2 days time, causing the resource to be overallocated.

4. Then, run the Resource leveling. This feature allows to resolve the overallocation by delaying some of the resource's tasks. In the end, you should see the 4 tasks being scheduled one after the after without any overallocation of their resource.

5. Additionally, since the created scheduling doesn't use any Jira dates, and Start & Finish dates of tasks are automatically calculated on the chart, these dates are not reflected in Jira in any way. if you want to change that, you can use the Copy to Jira functionality - it allows to write the automatically calculated dates on the chart into Jira field. 

I hope this helps. If you have more questions, please feel free to reach out to us directly at our support portal.

what is the criteria of which task goes 1st or 2nd ? is it issue key or creation date or something else ?

[Stepan Kholodov _Tempo_]

@Harini Kantheti there is a complex internal algorithm that considers a lot of different parameters to make that decision. You can control this yourself by using the Leveling priority parameter - tasks with higher priority will be delayed last. You can set it manually in the task that you want to be the earliest, and additionally in all other tasks, too.

Hi @Harini Kantheti ,

Are you using Gantt Charts for Structure (from Tempo) or something else here? Not sure if they support automatic calculations within their app, but you could use Jira automation to build those auto calculations for start and end dates based on estimates. Here's one example of how you could do it: Automate start date calculation in Jira with due date and original estimate 📚

Cheers,

I dont want to populate start date and end date on Jira yet. the reason being, i dont know which task developers would prefer to takeup. Overall my goal is to just get a summary view of how long their assigned tasks will take. Eg: 8 tasks, 2 days each 16 days is visually what date/day from today, any visual dependencies they need to be unblocked ... Repeat this with all the developers and find the critical path aswell.

Hi @Harini Kantheti 

Tempo Gantt (part of Tempo Software) primarily works with:

• Issue Start Date

• Issue Due Date (End Date)

• Dependencies

It does not automatically schedule issues sequentially based on Original Estimate and Assignee capacity.

So if you only provide:

• Assignee

• Original Estimate

• Project Start Date

Jira will NOT automatically calculate:

• Start date per issue

• End date per issue

• Continuous scheduling

In Tempo Planner you can:

1. Set team capacity

2. Make sure all issues have Original Estimate 

3. Assign all tasks to the same Assignee

But you must:

1. Create a custom “Start Date” field

2. Manually calculate start/end

3. Or use dependencies between tasks

4. Then let Tempo visualize them

Tempo alone does NOT do automatic sequential workload scheduling.

Any alternatives?

Yes — Planyway for Jira can partly help you achieve what you’re describing, and it’s often easier to set up than Tempo for this specific need.

However, it still doesn’t magically calculate task start/end dates only from original estimate and project start date — you need to enable scheduling logic. But Planyway does support auto-scheduling based on workload and capacity, which gets you very close to your desired behavior.

Here’s how Planyway can help:

✔ Auto Schedule Based on Assignee’s Capacity

Planyway has a workload and auto-planning engine that can:

• Assign tasks sequentially based on availability

• Use Original Estimate (if mapped to time field)

• Respect working calendars (weekends, hours per day)

• Show Gantt timeline per assignee

You will need to set up the start date of a task anyway but once it's set in the card you can drag it to the timeline and it will be stretched to the rights number of dates.
