More about the author

*article is a summary of presentation carried out during APIDays Madrid 2019 REST standard APIs are the most common, but GraphQL and gRPC APIs are gaining popularity, as well as doubts about the best application of these standards:

What are the characteristics and advantages of each of these standards?

What standard should we choose for our project?


To clarify these points, we will consider the requirements of 3 of the main use cases with APIs and understand how each standard can contribute in these cases.

Main cases of use with APIs:

  1. Experience APIs
  2. Open APIs
  3. Internal APIs

1) Experience APIs

They are APIs for consumption by Front-end Apps and Devices for digital experiences.

Below are some requirements:

  • Reduced data transfer time
  • Shorter response time
  • Use in conjunction with BFF standard
  • Fewer requests for screen rendering
  • Higher level of monitoring

2) Open APIs

They are APIs for integrations with partners and open innovation.

Some requirements are:

  • Simple user experience and following better known standards
  • Reuse of APIs
  • Detailed documentation
  • Higher level of security
  • Higher level of governance

3) Internal APIs

They are APIs for communication between microservices and internal integrations.

Below are some requirements:

  • Compatibility with the architecture of events or reactive architecture
  • Better performance
  • Greater scalability
  • Greater level of control and monitoring
Internal APIs

APIs REST, GraphQL and gRPC: Comparison

In the table below, we have compared the REST, GraphQL and gRPC standard features:

API Days Madrid 2019 - REST, GraphQL and gRPC
Main Diferences - REST, GraphQL and gRPC

What now? What is the best option: REST, GraphQL or gRPC?

To choose the best option for your project, we suggest making an eligibility matrix, where the requirements of the use case and a score for each standard will be.


E.g.: Experience APIs – REST, GraphQL and gRPC Eligibility Matrix

21 Product Management Frameworks

Effective product management is critical to the success of any product development process. It helps to ensure that everything to be done matches the needs or pain points of customers and that resources are optimally used. This means that product managers must be methodical in their approach.

Frameworks can help with this methodology, providing both a comprehensive and objective process for things such as opportunity evaluation, prioritization, and requirements definition.  Below are 21 must-know frameworks for anyone practicing the craft of Product:

1. Minimum Viable Product

Credited to Lean Startup author Eric Reis, this framework emphasizes the importance of learning when developing new products. The strategy, which is also called Lean Software Development, calls for the development of a minimal (or bare-bone) product for testing at first. The team builds a solution with minimal functionalities that are enough to solve a problem. This enables the gathering of customer feedback and validation of assumptions to know what can be done better.

2. Working Backwards

This framework literally reverses the product development process, starting with what usually comes later. It was created and popularized by Amazon and, so, is sometimes called the Amazon method. Your product team begins by imagining that the product has been built to identify whether the customer’s problem has been solved.

At the start, you write a press release announcing the product’s availability. The document describes the problem and what value the product delivers above existing alternatives. This helps to be really sure the product is worth building.

3. North Star Framework

Introduced by Amplitude, this framework centers on a single, most important metric – the North Star Metric. Startup advisor Sean Ellis describes this metric as one that “best captures the core value that your product delivers to customers.” The North Star Metric is complemented by a number of key inputs that help to drive it. Your team works to impact these key inputs with everything it does every day.

4. Business Model Canvas

This model aims to help make clearer how the product team will create value and to shorten the product development cycle. The business model canvas provides a complete, high-level view of the different strategic points crucial for bringing the product to market.

Businesses of various sizes use this model to understand and describe their business models more efficiently. It comprises elements that may vary from one business to another and is typically used together with the Value Proposition Canvas and other strategic management tools.

5. Job To Be Done

Also known simply as JTBD, this framework for focuses on identifying customers’ needs, based on scenarios rather than personas. Championed by Clayton Christiansen, it calls for a deeper understanding of the customers, including their goal or “job” that they would need your product to do. Job To Be Done shifts the center of attention from the product to customers. It helps to grasp the customers’ thought processes when purchasing so that product teams can know what to focus on.

6. Opportunity Solution Tree

Developed by Teresa Torres, this framework is a visual representation of how you aim to attain your desired outcome. The diagrammatic tool was designed to make simpler the discovery process and to enable the proper prioritization of opportunities. Torres designed the framework to help product teams know and focus on “the big picture” in their work. It assists in properly thinking through any decisions to be taken.

7. Weighted Impact Scoring

This is a popular prioritization framework among top product managers. The weighted impact scoring model involves ranking initiatives or features using a simple scoring model. You start by identifying some key criteria and then assign a weight (in percentage) to each one showing how important they are. Initiatives are scored based on these criteria and ranked accordingly.


Read more about the Weighted Impact Scoring 

8. RICE Prioritization

This framework developed by the team at Intercom is a very simple one. It calls for the evaluation of product ideas based on four factors, which the name derives from: Reach, Impact, Confidence, and Effort. A final score is generated for each initiative using these criteria. All initiatives are ranked using their final scores that indicate relative values to the product and company.

9. Design Sprint

Created by Jake Knapp at Google Ventures, Design Sprint is a five-step or five-day process that draws inspiration from design thinking. It aims at reducing the risk that could come with launching a product.

This design framework involves the team coming together to understand, design, prototype, and validate ideas before introducing a product or feature. It helps to quickly identify key problems as well as design and test their solutions.

10. Customer Journey Map

This is a visual representation of all the steps a typical prospect or customer takes when interacting with your product or service. The framework, sometimes called the 5 Es, helps to have a good grasp of the customer’s experience. It makes it easier for product managers to gain insights into customer behavior so that they can develop a strategy most fitting for the observed behavior.

11. Kano Model

Based on the ideas of Japanese professor Noriaki Kano, this framework is useful for identifying the attributes of a product that users will find most valuable. It features two axes: one showing how well a need is met and the other depicting how satisfied customers are as a result. The Kano Model helps to identify those features that are more likely to delight customers. Prioritize features that deliver the most delight relative to the cost of implementation.

12. Spotify Squads

This model shows what the culture that has helped Spotify to success is like. It involves product squads – small, cross-functional teams – that are autonomous. The framework is about empowering squads to choose what to work on to achieve a desired outcome rather than having tasks assigned to them. A key requirement is that the chosen work must match an organization’s overall strategy.

13. GIST Planning

The name of this framework comes from factors you need to guide true agile planning and execution, according to its creator. These are Goals, Ideas, Steps, and Tasks. Developed by Itamar Gilad, the GIST Planning framework is inspired by Lean Startup Growth Marketing and behavioral economics principles. Its goal is to lower management overhead, advance team autonomy, and expedite development.

14. 3 Pillars of Product

This 3-part framework created by product strategist Neal Cabage defines the most important elements or aspects of product management. These three key parts are product or opportunity discovery, product planning, and product development. Product managers and teams can use the model as a good guide for developing winning solutions.

15. Double Diamond

Developed by the British Design Council, the Double Diamond framework is a design process model involving four phases or elements. These are Discovery, Definition, Development, and Delivery. The four stages apply to all approaches for creating something new, according to its creators. This process is iterative and involves two types of thinking: divergent and convergent.

16. DACI

DACI is an acronym standing for Driver, Approved, Contributor, Informed. It is a roles and responsibilities framework that helps drive team alignment by clarifying who is responsible for what within a team or project. It is similar to the more well-known RACI framework, but DACI is particular relevant to Product Management because it emphasis an ownership model rather than a delivery model, which better aligns to the Agile Product ethos. Use this framework when setting out on a new initiative or configuring a new team, to clearly articulate the PM’s responsibilities and how to interact with leadership, stakeholders, and other contributors. The below framework exemplifies how one might articulate ownership within the product development team more probably.

17. Product Team Competencies

This is yet another of the frameworks created by Cabage. Product Team Competencies was designed to make the clear vital skills that are needed for project management, especially when it comes to digital products. The model is a 2-dimensional spectrum of skills or capabilities. It places product leaders on one of two sides: strategic or tactical and external or internal. The Product Team Competencies framework is useful for assessing, conveying, and enhancing overall team capabilities.

18. CIRCLES Method

A design framework by Lewis Lin, the CIRCLES Method provides a guide on how to provide thoughtful, detailed responses to design questions. It is useful for deeply understanding what to design and why it is needed. The framework’s name comes from the steps to follow when answering design questions:

19. Product-Market Matrix

This framework is also known as the Ansoff Matrix after the mathematician Igor Ansoff who developed it in 1957. The Product-Market Matrix, or the Product-Market Expansion Grid, is a 2×2 matrix showing four possibilities: market development, product development, market penetration, and diversification. Businesses typically use it to analyze and devise their growth strategies.

20. Innovation Adoption Curve

The Innovation Adoption Curve is a model of how and why a new product or innovation is adopted. Its creator, Everett Rogers, classified adopters into five categories: Innovators, Early Adopters, Early Majority, Late Majority, and Laggards. The framework highlights the need to approach each group differently when marketing.

21. Hooked Method

Coming from Nir Eyal’s 2014 book “Hooked,” this model describes a user’s interactions with a product through four stages. It is a guide on how to build habit-forming products. The four steps or phases identified as being key for such products are trigger, action, reward, and investment.
