FAQs

How do we define the goals for our data analysis project?

Understanding your goals is the first step. Know what questions you want to answer. Discuss with your team what insights are most valuable. This helps the data analyst understand your needs!

What information should we give to the data analyst initially?

Start by sharing all relevant data. Include any data sources you have, like spreadsheets or databases. Be clear about how often this data is updated. This helps the analyst know what they have to work with.

How can we agree on what the data analyst should deliver?

Talk about what you want the final product to look like. Do you want a report, a dashboard, or just insights? Be specific, so the analyst knows what to focus on.

What timeline should we set for the project milestones?

Set a clear timeline with start and end dates. Break the project into smaller tasks with their deadlines. This helps track progress and keeps everything on schedule!

How often should we check in with the data analyst during the project?

Regular check-ins are important. Decide if you want weekly or bi-weekly meetings. This keeps communication open and helps catch any issues early.

What should we do if we need changes during the project?

Plan for changes in advance. Discuss how you'll handle changes with the analyst before starting. This makes it easier to adapt without stress.

How do we review the data analyst's work for quality?

Set clear criteria for what good work looks like. Use these to check the work once it's done. Comparing actual results against expectations keeps quality high.

How should we manage data privacy and security with the analyst?

Discuss how to protect your data. Share only what is necessary. Use secure methods, like encryption, for sharing sensitive information.

What should we do to onboard the data analyst effectively?

Create a clear onboarding process. Include introductions to your team and tools they will use. Make sure they know who to contact with questions.
