What Google Learned From Its Quest to Build the Perfect Team

Most Valuable Idea

The most important condition to increase groups performance is psychological safety. Members of the best performing groups at Google are:

1-Spoke roughly the same amount (equal conversational turn-taking).

2-Scored high on social sensitivity test (Reading the Mind in the Eyes test – guessing what people are thinking or feeling from photos of people’s eyes).

"As the researchers studied the groups, however, they noticed two behaviors that all the good teams generally shared. First, on the good teams, members spoke in roughly the same proportion, a phenomenon the researchers referred to as ‘‘equality in distribution of conversational turn-taking.’’ On some teams, everyone spoke during each task; on others, leadership shifted among teammates from assignment to assignment. But in each case, by the end of the day, everyone had spoken roughly the same amount. ‘‘As long as everyone got a chance to talk, the team did well,’’ Woolley said. ‘‘But if only one person or a small group spoke all the time, the collective intelligence declined.’’

"The good teams all had high ‘‘average social sensitivity’’ — a fancy way of saying they were skilled at intuiting how others felt based on their tone of voice, their expressions and other nonverbal cues. One of the easiest ways to gauge social sensitivity is to show someone photos of people’s eyes and ask him or her to describe what the people are thinking or feeling — an exam known as the Reading the Mind in the Eyes test. People on the more successful teams in Woolley’s experiment scored above average on the Reading the Mind in the Eyes test. They seemed to know when someone was feeling upset or left out. People on the ineffective teams, in contrast, scored below average. They seemed, as a group, to have less sensitivity toward their colleagues."

Project Aristotle – Other findings:

1.Psychological Safety:

Of the five key dynamics of effective teams that the researchers identified, psychological safety was by far the most important.Psychological safety refers to an individual’s perception of the consequences of taking an interpersonal risk or a belief that a team is safe for risk taking in the face of being seen as ignorant, incompetent, negative, or disruptive. In a team with high psychological safety, teammates feel safe to take risks around their team members. They feel confident that no one on the team will embarrass or punish anyone else for admitting a mistake, asking a question, or offering a new idea.

Taking a risk around your team members may sound simple. But asking a basic question like “what’s the goal of this project?” may make you sound like you’re out of the loop. It might feel easier to continue without getting clarification in order to avoid being perceived as ignorant.

2.Dependability:

Team members get things done on time and meet expectations.

3.Structure and clarity:

High-performing teams have clear goals, and have well-defined roles within the group.

4.Meaning:

The work has personal significance to each member.

5.Impact:

The group believes their work is purposeful and positively impacts the greater good.

How I explained REST to my brother.

Who is Roy Fielding?

He is one of whom helped write the first web server,that sent documents across the internet and then he did a ton of research explaining why the web works the way it does , that made His name is on the specification for the protocol that is used to get pages from servers to your browser.

---

Why don’t the techniques that we use today work well when we need to be able to talk to all of the machines in the world?

Because they weren't designed to be used like that.When Fielding and his colleagues started building the web, being able to talk to any machine anywhere in the world was a primary concern.

What is the HTTP protocol that Fielding and his friends created?

HTTP is all about applying verbs to nouns.

What does a GET do?

When we go to a web page, the browser does an HTTP GET on the URL you typed in and back comes a web page.(get the representation of a resource (the website) by its URL).

What does a POST do?

Allows one system to add something to another system.

What does PUT do?

Allows a system to replace something in another system.

What does PATCH do?

Allows a system to do a partial update in another system.
