Syllabus

Lesson 1: Data Dictionaries: Building a Shared Language for Data

In this introductory lesson, learners explore the foundational role of data dictionaries in building a shared understanding of data across teams. They’ll discover how standardized data definitions prevent miscommunication, reduce costly errors, and create a reliable foundation for analysis and reporting. Through relatable stories and hands-on activities, learners will practice documenting and structuring a data dictionary for practical use. The lesson sets the stage for why clarity, consistency, and collaboration are essential to effective data management, especially when data is shared between technical and non-technical colleagues.

Lesson 2: Data Quality in Action: Catching and Correcting Errors

In this lesson, learners will dive into the practical realities of data quality—what it means, why it matters, and how to spot issues before they become costly problems. You'll explore real-world examples where even small mistakes in accuracy, completeness, or consistency led to major setbacks for teams and organizations. Through engaging stories and hands-on practice, you'll learn to apply a data quality framework, identify the most common types of errors, and use step-by-step validation techniques to detect and fix problems in real datasets. You'll also see how poor data quality can undermine trust, mislead decision-makers, and create unnecessary work—while strong quality controls can turn data into a true business asset. This lesson is about more than just finding and fixing mistakes. It’s about building habits and routines that ensure data remains reliable, up-to-date, and fit for purpose—no matter how fast your organization grows or changes. By the end, you'll know how to assess quality, spot red flags, and build a culture where everyone values and protects data integrity.

Lesson 3: Data Resilience: Leading Through Errors, Recovery, and Reflection

In this final lesson, learners explore how to lead and manage data teams through setbacks—whether it’s a spreadsheet failure, reporting misstep, or cross-system data breakdown. They'll learn to respond constructively to errors, guide teams through recovery, and use communication strategies to reinforce shared understanding of data standards. Through real-world case studies and reflection techniques, learners will practice designing communication routines, post-incident reviews, and proactive alignment strategies that help teams stay informed, accountable, and resilient—even under pressure.
