Jira Project Estimator

Every software team at some point will be asked: "When will X be finished?"

And then you can either:

• A) Estimate the remaining work with any technique you like. (E.g. a spreadsheet, compare with similar past experiences, rule of thumb, velocity, etc.)
• B) Just say the date your client wants to listen. (Please never do this)

We know giving estimates is hard in software.

We know that sometimes estimates are considered as compromises by clients, and we can be prisoners of our own words.

We know that it's better to know that we are not going to meet the deadline as early as possible, so we can plan for the future and act accordingly.

So the purpose of this tool is to help you monitor your team's progress and automatically get estimated finish dates, and to make it something quick and easy to use. You just need to estimate your Jira tickets and the tool will do the rest!

💭 Considerations

1. The tool tracks progress and generates estimates for the Epic, based on its Issues points and status (To Do, In Progress, Done, ...).

2. The tool considers all types of Issues (Story, Task, Bug, ...).

3. The tool does not track progress or generate estimates for Issues without Epic.

4. The tool does not consider Sub-Tasks.

5. For calculating average velocity and generating estimates is the unit of time is the week. This is to avoid having to consider if the team uses sprints, and eventually the sprint length which could be different for each team. Also, estimates in number of weeks should be fine for everyone.

6. By default there are 2 estimations which are calculated based on the average velocity since: (1) the implementation start week; (2) the last 3 weeks. You can also ask for a 3rd estimation based on the average velocity you expect to achieve by using the Expected average filter.

7. The tool considers that weeks start on Monday and end on Sunday. Why do I mention this? Because if you started the implementation of a project on a Friday, the tool will consider that the implementation started on the previous Monday, and therefore your average velocity will be lower than expected. In this case you can either live with this difference, or set the Epic start date in Jira and say implementation started the following Monday. If you need to use another custom field for the start date, you should set the JIRA_START_DATE_FIELD_CODES environment variable, which allows comma separated values (e.g. customfield_10015,customfield_10034)

8. If you want to estimate just a subset of an Epic, you can make use of Jira labels to filter the Issues you want to consider. First label your Issues in Jira, and then use the Label filter.

9. The tool allows you to consider a level of uncertainty when calculating an estimation, with 5 possible values: Empty, Low, Medium, High, Very High. For each value you can set a percentage associated to it, by setting the LOW_UNCERTAINTY_PERCENTAGE, MEDIUM_UNCERTAINTY_PERCENTAGE, HIGH_UNCERTAINTY_PERCENTAGE, VERY_HIGH_UNCERTAINTY_PERCENTAGE environment variables. What this will do is, for example, if right now you have 20 points remaining, and you set the MEDIUM_UNCERTAINTY_PERCENTAGE to 20% and select Uncertainty level filter to Medium, the tool will consider that you have 24 points remaining and calculate the number of weeks remaining based on that.

10. The calculations are more accurate when you estimate ALL the Issues and after multiple weeks of work (the first few weeks is expected to see unaccurate estimates).

11. The tool works for Scrum, Kanban, or any other Jira board type. By default it might just work with Scrum boards by using the existing points field, and if you need to use another custom field, you should set the JIRA_STORY_POINTS_FIELD_CODES environment variable, which allows comma separated values (e.g. customfield_10016,customfield_10034)

12. The tool allows you to define your own set of ticket statuses. By default it uses To Do for "not started", Done for "finished", and every other status for "in progress". If you need to use a different set of statuses, should set the TO_DO_STATUSES and DONE_STATUSES environment variables, which allows comma separated values and is case insensitive (e.g. TO_DO_STATUSES=To do,Open,pending review and DONE_STATUSES=done,resolved,Closed)

🔌 Connecting to your Jira instance

Create an API token

Extracted from: Manage API tokens for your Atlassian account

You can use an API token to authenticate a script or other process with an Atlassian cloud product. You generate the token from your Atlassian account, then copy and paste it to the script.

Steps:

1. Log in to https://id.atlassian.com/manage-profile/security/api-tokens
2. Click Create API token.
3. From the dialog that appears, enter a memorable and concise Label for your token and click Create.
4. Click Copy to clipboard, then paste the token to your script, or elsewhere to save:

Notes:

• For security reasons it isn't possible to view the token after closing the creation dialog; if necessary, create a new token.
• You should store the token securely, just as for any password.

Set the necessary ENV vars

JIRA_API_TOKEN=<your-api-token>
JIRA_SITE_URL=https://your-domain.atlassian.net
JIRA_USERNAME=user_email@example.com

👥 Managing users

There are no web pages for creating or deleting users.

You can create users with the following command in the rails console:

User.create(first_name: 'First', last_name: 'Last', email: 'admin@example.com', password: 's3cur3_P4ssw0rd#!')

You can delete users with the following command in the rails console:

User.find_by(email: 'admin@example.com').destroy!
