+    "description": "One key responsibility of Engineering Managers is to establish clear communication across organisational functions, as they often have greater context and understanding of high-level processes. The job of establishing working cross-functional collaboration often includes defining areas of responsibility, formalising the communication streams, aligning goals, and resolving conflicts between teams.\n\nOne of the common symptoms of poor cross-functional collaboration is when team members are blocked by other teams. To tackle this, teams need a culture of open communication and trust that surfaces problems as early as possible. After problem is identified at a team level, Engineering Manager steps in and collaborates with other managers to improve the situation or escalate it to higher levels when necessary.\n\nEffective cross-functional collaboration establishes clearer expectations from all organisation functions and improves predictability of all participants.\n\nAs an example of tooling for cross-functional collaboration, teams can have publicly available Service Level Agreements (SLAs) or well-documented external communication processes. These tools help external teams set clearer expectations when working with the team, reducing ambiguity and friction.",

It allows you to define custom rules or restrictions on the values that can be inserted or updated in one or more columns. `CHECK` constraints help maintain data quality by preventing invalid or inconsistent data from being added to the database, ensuring that only data meeting specified criteria is accepted.\n\nLearn more from the following resources:",
