Originate Guides - Storywriting Best Practices

Good user stories create efficient development processes.

At Originate, we strive to enable engineers and solutions through our product management, especially including our Storywriting practices.

Storywriting is your best friend:

  • Storywriting fleshes out the details as the story matures
  • Uncover edge cases not immediately obvious
  • Developers should only bother you if they have questions or are confused
  • AC can be negotiable

Stories are a developer’s best friend, too!

What is a user story?

Definition: An empirical unit of development work that delivers tangible value to the end user or consuming system.

The “user” in user story refers specifically to the user or system CONSUMING the functionality in the feature being built.

Recommended size: Smallest amount that delivers value

There should be some room for PMs to "use their judgement" in terms of sizing a story properly. Sometimes it's easier for all parties to lump a couple of small things into one story, or break a big story into two smaller ones, even if each one independently doesn't really deliver value. It should be the exception, not the rule though.

Storywriting Criteria & Best Practices

Stories are made more complete by following these guidelines:

  • Epics are clearly defined and represent a complete problem that needs solving
  • Twitter example: "Logged Out User Experience" is a better Epic than "Redesign Homepage". The latter might be the solution for the former problem, but keeping it broader/holistic allows the team to come up with different solutions that might not include a redesigned home page.
  • Stories are written in an appropriate format to convey the desired user behavior

    • A consuming user or system is specified
    • An action is specified
    • A motivation is specified
  • Acceptance Criteria details a list of expectations and demonstrates thinking through the story
  • Stories tracking system (JIRA, Pivotal, etc.) is used effectively by all team members

    • Kept up-to-date
    • Is the source of truth (not whiteboards)
    • Used frequently to discuss the details of stories and acceptance criteria
    • Link-Dependencies and Flag-Blocks are used between stories and teams
  • Product Priorities are accurately reflected in Story tracking system (both for Epics and stories)
  • Non-developer QA optimally tests the feature against the AC to determine completeness

Story Estimation

Epic Estimations are rough estimates designed to help PMs prioritize.

Epic Estimations:

  • of weeks: 0.5, 1, 2, 4

  • Estimated by Tech Lead/Architect
  • Completed before stories are written
  • Estimated before each release

Story Estimations are more correct estimated designed to manage for sprint work.

Story Estimations:

  • of points: 1 - 10 (but stories > 5 are a red flag)

  • Estimated by Tech Lead/Architect/QA
  • Tech lead is accountable for delivering stories on time
  • Estimated before each sprint

Recommended formats for user story

Persona User Story

Most often used format for describing features. Link: persona user story

As a [ END USER ] , I want to [ TAKE AN ACTION ] , so that I can [ MOTIVATION ]
role What is the “thing” the Why does the user want
user user wants to do? to do this “thing”?
admin The function? What’s the benefit?
developer The feature?

Example: As a Model Researcher, I want to log into the platform, so that I can test the new model(s).

Feature Injection Story

Good format for describing features especially requests that are more technical in nature. Link: feature injection syntax

In order to [ DELIVER BUSINESS BENEFIT/VALUE ] , As a [ ROLE ] , I want [ FEATURE ]
Why does the user want user What is the “thing” the
to do this “thing”? admin user wants to do?
What’s the benefit? developer The function?
What's the business value? system

Example: In order to test the new model(s), as a Model Researcher, I want to log into the platform.

Acceptance Criteria / Conditions

A detailed list of expectations this feature requires to be considered “complete” for demo or during assessment; product acceptance testing.

This list can (and should) evolve! It’s never set in stone.

Acceptance Criteria (AC):

  • Display form fields for: username, password
  • Display a “log in” button underneath the form fields
  • On click of the “log in” button, user authentication is attempted
  • If success, direct user to Home Page
  • If failure, display error message “please try again”
  • Validate form fields such that only alphanumeric characters are accepted
  • If form does not validate, highlight red the field in violation
  • “password” form field should display only **** characters

QA Review

Every story needs to be fully tested. This is generally done by a dedicated QA team member, and in the absence of that, the Product Manager.

QA may review and then signal to Product Manager to review and close.

  • Ensure process is defined and followed through workflows
  • Test that all acceptance criteria is true
  • Test that the feature is what the Product Manager intended
  • Accept/reject stories regularly and often
  • Review feature tests created/updated to support automated testing
  • Augment feature tests created/updated to support further automated testing
