Persona Definition

A single representation of a cluster of target users who represent similar behaviors, goals, and motivations.

Why do we need Personas?

To create products that are useful, usable, and desirable for our customers, we have to understand who our users are and what they need.

If we don’t understand our users…

We make decisions for ourselves (self-referential design).

We make decisions based on assumptions, or what we “think” we know.

Creating a persona

Creating Enterprise Personas

  • Review the organization chart to identify the actor roles
  • Identify the hero’s of the story and the supporting actors
  • Collect data that defines the role:
    • Position profiles describe their jobs
    • Performance Management documents may define role objectives and drivers of behavior

Define your goal and what are your research questions?

Insight categories – starter list…

  • Needs and Priorities
  • Goals
  • Motivations for using your product Processes, Behaviors & Habits
  • Pain Points
  • Tools and Technology

How many users should be interviewed or observed?

  • Talk to 5-30 participants
  • Trends are often observable from just 5 people
  • Law of diminishing returns applies
  • More than 5 will deepen your understanding
  • Identify extreme users

Analysis and Segmentation

  • Talk to SMEs to identify attributes that are important within the scope of use
    • Tenure
    • Geography
    • Occupancy
    • Education / Background
    • Technology competency
    • Demographics
    • Context (environments, devices, psychology)
  • Understand similarities and differences among each attribute
    • g. Technology – Low, medium, high?
  • Break down the attributes to identify patterns
    • Make a grid with common attributes across the top & participants down the side
    • Describe how each participant scores against each attribute
    • Compare and contrast data and identify the similarities

  • Why: Helps us understand how people currently use the product and situational considerations we can apply to the product.

Frustrations and pain points

  • What: Describe the issues they are dealing with on a daily basis.
  • Why: Understand and react to the user’s state of mind. Be empathetic to their situations and difficulties when making design decisions.


  • What: A real quote from qualitative research that embodies that persona’s segment. This should reflect their attitude and behavior.
  • Why: Bring the user’s voice into the persona. Make them sound like a real person.
  • How: Extract single quote or combine multiple user comments to create believable quote. Don’t get too wordy.

Prioritize Features & Ideas

Use personas to score different feature ideas.

  • Helps identify which features will useful for who.
  • Features that benefit more personas can help prioritization (coupled with other measurements biz value, feasibility and frequency of use)

Measurement framework could be:

  • -1: Hurts persona
  • 0: Persona is neutral
  • +1: Helpful to persona
  • +2: Persona LOVES this feature! It’s a must-have!
