About the Entity Relationship Diagram template

What is an entity relationship diagram?

An entity relationship diagram (ERD), is a structural diagram that allows your team to portray relationships between actors in a system. This type of diagram is used in databases or information systems design. ERDs are typically used to visualize relationships between different roles (like a product manager’s relationship with a developer), tangible business objects (like a product or service), and intangible business objects (like a backlog). Read on to find out how these powerful tools can help your team.

Advantages of using entity relationship diagrams

ERDs allow your team to visualize how complex, interconnected entities connect and overlap in a system. This powerful tool is simple to understand and use, making it beneficial for both new and seasoned teammates to collaborate.

When do you use an ERD? Here are some examples: 

  1. To educate your teammates: ERDs are powerful tools for educating your teammates on the relationship between systems or entities. 

  2. To onboard new teammates: Because ERDs are visual, they’re an easy way to showcase information for new hires.

  3. Whenever you need to create documentation before making a change: When preparing to change a process, it can be useful to document your existing process. By doing so, you ensure that all necessary measures are in place in case you need to return to the previous process or iterate on the current one.

Create your own entity relationship diagram

Making your own entity relationship diagram is easy, using Miro’s template. Simply select this Entity Relationship Diagram template and follow these steps:

Step 1: Identify all entities in the system. An entity should appear only once in a diagram. Create rectangles for all entities and name them properly.

Step 2: Add meaningful names to the entities so they’re easy to understand. 

Step 3: Identify relationships between entities. Connect the relationships with lines or arrows.

You can customize the diagram according to your needs. For example, you can add shapes, change colors, make sticky notes, and draw arrows. Next, add documents and/or images to clarify and enhance your template. Invite your teammates to join and collaborate with you on your ERD. Any changes will be saved automatically.

Ready to get to the root of the problem? There’s no simpler way to do it than the 5 Whys technique. You’ll start with a simple question: Why did the problem happen? Then you’ll keep asking, up to four more times, until the answer becomes clear and you can work toward a solution. And Miro’s features enhance the approach: You can ask team members questions in chat or @mention them in comments, and use color-coded sticky notes to call out issues that are central to the problem at hand.

SMART Goals Template

Setting goals can be encouraging, but can also be overwhelming. It can be hard to conceptualize every step you need to take to achieve a goal, which makes it easy to set goals that are too broad or too much of a stretch. SMART is a framework that allows you to establish goals in a way that sets you up for success. SMART stands for Specific, Measurable, Attainable, Relevant, and Timely. If you keep these attributes in mind whenever you set goals, then you’ll ensure your objectives are clear and reachable. Your team can use the SMART model anytime you want to set goals. You can also use SMART whenever you want to reevaluate and refine those goals.
