What is a feedback loop?

It’s about creating a streamlined process of getting customers’ feedback.
As feedback it could be:
* Net Promoter Score (NPS)
* New feature votes
* Enjoying an ebook or material provided

Feedback on FAQ Items (kind of “did you find it useful”

The concept of product-led approach is to streamline collecting customer feedback and then use this feedback to optimize the user’s experience or your product. A product without a feedback loop is like “flying a plane without instruments”

What is an iteration loop?

It’s a streamline process, where you product includes the ability to mature through iterations.

Although adopting the agile methodology seems to be to correct approach, agile alone may lead you in loosing your focus of the overall picture to address one feature at the time.
You definitely need to build your product by having a Rapid, early validation of ideas that will allow you to mature through iteration.

What is a viral loop?

A sticky product (a product that has a great usage cohort) is not synonym to a viral-product.

A sticky product is one that becomes part of people’s daily routine and is super-simple to onboard new users into – no matter how they find your product.

A viral product is a product allowing existing users to bring more users. It could be part of the product-core (i.e. in a messenger, inviting your friends to also use the messenger, or sharing a message out-of-the user’s network) or part of the product-ecosystem (i.e. refer a friend and reward schemes are the tinder for the fire of virality, as they make it easy to turn your customers into advocates.)

Enabling growth and creating virality comes down to ease and impact.

Enable your product to expand and allow your customers to invite their colleagues and peers to refer. Create exponential growth that is outside of your control – it’s not as scary as it sounds!
