What is Data Quality?
The accuracy, completeness, consistency, and timeliness of data in business systems, determining whether data can be trusted for decision-making and operations.
Understanding the Details
Data quality is the foundation that every data-dependent activity rests on. Inaccurate CRM data means wrong lead routing, unreliable forecasts, and wasted sales effort. Incomplete contact records mean missed personalisation opportunities. Inconsistent naming conventions mean duplicate records and conflicting reports. Data quality encompasses accuracy (is it correct?), completeness (are fields filled?), consistency (do records follow the same format?), timeliness (is it current?), and uniqueness (are there duplicates?). The challenge is that data quality degrades naturally — people change jobs, companies rename, and manual entry introduces errors. Maintaining quality requires ongoing processes, not one-time cleanups.
How It Works in Practice
CRM audit
A data quality audit reveals 30% of contacts have outdated job titles, 15% have duplicate records, and 20% are missing company size — undermining lead scoring accuracy.
Automated validation
Form submissions run through validation rules that standardise company names, validate email domains, and flag obviously incorrect data before it enters the CRM.
Ongoing enrichment
Monthly enrichment passes update changed job titles, append missing fields, and flag contacts who've left their companies.
Why It Matters
Every downstream activity — targeting, personalisation, scoring, forecasting, reporting — depends on data quality. Bad data creates compounding problems across your entire operation.
What People Often Get Wrong
Data quality is a one-time project. Actually, data decays continuously and quality requires ongoing processes and monitoring.
Technology alone solves data quality. Actually, it requires a combination of processes, automation, ownership, and cultural commitment.
Perfect data is achievable. Actually, the goal is 'good enough' data quality that enables reliable decisions and efficient operations.
