Find the optimal number of features for your product

Find the optimal number of features for your product

A foundational question in product design is what features to add to a new product.  The more features we add, the more complicated and expensive the product becomes.

There is no uniform formula that will allow us to find the optimal number of features for our product. However, a three-step process can help.

Define the core set of features

Define the core set of features

The core set of features is critical to your product launch. This is often the most challenging part of product design.

  • Apply the Pareto principle: 80% of the value comes from 20% of features. Define the one job that will add the most value to your target audience.
  • Building minimum viable product (MVP): An MVP allows you to strip your product down to its core and will enable you to validate if your initial idea is good.
  • Beat the fear of getting on the market too early. You can give access to your MVP to a small group of users and track their performance.

Learn how users interact with your product

Learn how users interact with your product

The first product release allows you to learn how users react to the added features and understand what engages and drives them.

  • Track features people use most often. Most users will use a particular set of features. Therefore, it's vital to improve the user experience of those features because they provide the most value.
  • Introduce a feedback mechanism in your product so that users can share what they think about your product.
  • Carefully analyse user feedback. Don't consider everything users say but learn if the feature is valuable for a large segment of users.

Introduce gradual, not radical, changes

Use small changes to adjust your product: It is faster and less expensive, and it is easier to track the effect of those changes.

Key metrics to measure:

  • Behavioural - how easy is your product to use?: Task Success, Task Time, Error rate.
  • Attitude - how do users feel about your product?: Net Promoter Score, System Usability Score.

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
