What an experimentation team running A/B tests can look like

Experimentation teams come in many forms and shapes. Agencies or experts doing CRO need to know a lot: how to design, all about UX patterns, data, how to setup a/b-tests, how to analyze a/b-tests, how to do UX research, and so on. Often CRO or experimentation is about teamwork. 

You see our preferred team in the picture, but we adjust the team to the needs of the organization.

The professions you'll need to able to run experimentation programs: 

• Someone to lead the project. These are often called an experimentation strategist, CRO specialist or consultant. Often connects with the point of contact on client side. 
• Designer. Someone to design the experiments (according to brand guide) and think along with the strategist about the UX. 
• Developer. Someone to develop te experiments in code. To setup the correct events. Potentially build an in house testing tool. Also informs about UX and possibilities of the web. 
• Analist. Does pre-test analysis, analyzes the data of research and does the post test analyses.

Where in an organization does CRO and Experimentation live?

I've seen CRO being part of marketing teams, product teams or as a centralized agency within a big company. 

• Marketing, eCommerce or Digital team
• In a Product team
• As an agency within the company servicing different brands or departments 
• Decentralized CRO teams with different departments with one centralized Centre of Excellence
