Have you heard of the acronym SIPOC? If not, it might just become a game-changer for your Product team. By leveraging a SIPOC tool, you can create better-structured and more thoughtfully developed user stories, addressing common frustrations your engineering team might face regarding clarity, detail, and completeness.
For Agile and Lean Startup practitioners, a SIPOC tool offers valuable benefits across multiple areas, including product discovery, sprint planning, and—most notably—EPIC and user story development.
But what exactly is SIPOC? An acronym for Suppliers, Inputs, Process, Outputs, and Customers, SIPOC is a versatile tool rooted in process improvement methodologies. It first emerged in Total Quality Management programs in the late 1980s and has since become a cornerstone in frameworks like Lean Manufacturing, Six Sigma, Business Process Management (BPM), and Total Quality Management (TQM).
If you’re in a quiet place, you might have just heard the collective groan of startups and small-to-midsized businesses at the mention of these process improvement terms: Six Sigma (Ugh!), TQM (Agh!), BPM (No, no, no!). But here’s the thing—a good tool is a good tool, no matter where you find it. If it can help you succeed in your product management role, does it really matter what others think. I’m not suggesting process-allergic acolytes abandon their beliefs—just try out a SIPOC and add a sprig of GenAI to enhance your user story development.
What makes SIPOC so effective? Its simplicity and clarity. By providing a high-level overview of a process, SIPOC facilitates communication among stakeholders and identifies improvement opportunities.
If your goal is to elevate your EPICs and user stories while fostering stronger collaboration between product and engineering, SIPOC might just be the tool you’ve been looking for.
Applying a SIPOC to User Story Development
Early in my career, I received valuable training in Six Sigma, Lean Manufacturing, and Agile methodologies as a product manager. This comprehensive exposure provided me with a robust foundation for process improvement and value delivery. The integration of these methodologies allowed me to develop a unique skill set that bridged the gap between operational insights and product development needs.
One particularly useful tool I adopted was SIPOC, which I initially applied to enhance my productivity in understanding target user processes and developing user requirements. Over time, I found SIPOC and similar tools to be invaluable in various situations, from analyzing current processes for improvement to refining user requirements.
Using a SIPOC as an initial step in generating user stories offers significant advantages over starting directly with user story development. This approach compels practitioners to consider specific actions performed on inputs and any resulting modifications to outputs.
SIPOC offers several key advantages:
1. It helps organize thoughts about discrete process inputs, outputs, and the conversion process itself.
2. It aids in structuring the brain to identify all stakeholders in the process.
3. It helps product managers identify changes to objects or entities throughout the process.
4. It assists in identifying both permanent and temporary data structures needed for a process
An Engprax study conducted in early 2024 revealed that projects with clear requirements before the software development process began experienced a 97% increase in success rates...(er, duh. I'm self-aware)
Practical Example: Grocery List Construction
To illustrate the utility of SIPOC, consider the common example of grocery list construction. In this scenario, SIPOC can be used as a quick framework for generating user stories.
Consider the grocery list example above:
Family members (suppliers) have items they want to include on the grocery list (input).
The action is submitting these items for inclusion.
The output is a modified draft of the grocery list.
Without a SIPOC, you might overlook this transaction - the process of family members thinking of items and communicating them to the grocery list creator for addition to the draft.
User Stories: Grocery List User Story Descriptions (Perplexity.ai Generated)
I fed the SIPOC table into Perplexity AI, and here are the user story descriptions it generated. I did not modify these descriptions for this example, for one primary reason: they are quite accurate for an initial review. If I were to move forward with this task, I would certainly modify them in some way before adding the remaining content needed for each user story, such as acceptance criteria, artifacts, and mocks.
As a family member, I want to submit my requested items for the grocery list, so that my needs are included in the shopping.
As a husband, I want to gather all submitted requests from my family, so that I can create a comprehensive draft grocery list.
As a husband, I want to make a request for my family to review the drafted grocery list, so that everyone can provide input.
As a family member, I want to review the drafted grocery list, so that I can ensure all necessary items are included.
As a family member, I want to modify the drafted grocery list, so that I can add or remove items as needed.
As a husband, I want to review the modifications made by family members, so that I can update the draft accordingly.
As a family member, I want to approve the final version of the grocery list, so that I can confirm my agreement with the planned purchases.
As a husband, I want to finalize the approved grocery list, so that it's ready for shopping.
As a husband, I want to have a grocery list ready for shopping, so that I can efficiently purchase all necessary items for my family.
Benefits of SIPOC-Driven User Stories
The structure of SIPOC encourages product managers or product owners to think in terms of discrete actions on specific inputs producing distinct outputs. This approach naturally leads to more atomic-level user stories, which can be beneficial in several ways:
Clarity: It provides a clear understanding of each step in the process.
Testability: Atomic-level stories are easier to test and validate.
Flexibility: It accommodates various development team preferences, from complex multi-action stories to simple, discrete ones.
Starting with the most discrete level for a singular action performed on an input to produce a singular output provides a solid foundation. From this base, more complex user story structures can be developed as needed.
Conclusion
While teams may prefer different levels of complexity in user stories, starting with SIPOC-based atomic-level stories ensures a thorough understanding of the process. This approach facilitates the creation of clear, testable user stories with well-defined acceptance criteria, providing essential building blocks for effective story development.
Using SIPOC won't solve all the challenges of user story development, especially improving outcome quality, which requires talking to customers (see my earlier post on customer discovery for tips and tools). However, it can boost the overall quality of user stories. The focus should be on making steady progress toward better outcomes, rather than striving for perfection.
