User interviews are a key tool in product development, offering deep insights into user needs, preferences, and behaviors. As part of qualitative (qual) user research methods, user interviews provide nuanced, detailed feedback that can guide product teams in making informed decisions. This article will explore the role of user interviews in product development, highlighting the importance of qualitative research and offering practical techniques to get the most from your interviews.

Types of User Research Methods: Qualitative vs. Quantitative

Before diving into user interviews specifically, it’s important to understand where they fit in the broader spectrum of user research methods.

Quantitative User Research Methods

Quantitative (quant) research methods are data-driven and focus on measurable, numerical insights. These methods involve collecting large amounts of data to identify trends and patterns. They answer "what" questions, such as:

• How many users complete a particular task?
• How long does it take users to perform a certain action?
• Common quantitative research methods include:

Surveys: Large-scale questionnaires that provide statistical insights into user preferences and behaviors.

Analytics: Data from user interactions with a product, such as click rates, time spent on pages, and conversion rates.

A/B Testing: Comparing two versions of a product or feature to determine which performs better.

Qualitative User Research Methods

Qualitative (qual) research methods focus on understanding the "why" behind user actions and decisions. They aim to explore users’ motivations, feelings, and experiences. Qualitative methods provide rich, in-depth insights that are essential for understanding user behavior at a deeper level. Common qualitative research methods include:

• User Interviews: One-on-one conversations with users to explore their experiences and perspectives in detail.
• Focus Groups: Group discussions that provide a range of perspectives on a specific topic.
• Usability Testing: Observing users as they interact with a product to identify usability issues.
