๐ Data Quality Monitoring Summary
Data quality monitoring is the ongoing process of checking and ensuring that data used within a system is accurate, complete, consistent, and up to date. It involves regularly reviewing data for errors, missing values, duplicates, or inconsistencies. By monitoring data quality, organisations can trust the information they use for decision-making and operations.
๐๐ปโโ๏ธ Explain Data Quality Monitoring Simply
Think of data quality monitoring like checking your homework before handing it in. You look for mistakes, missing answers, or anything that does not make sense. This helps make sure that what you turn in is correct and complete, just like making sure data is right before it is used.
๐ How Can it be used?
Set up automated checks to alert the team when sales data in a retail dashboard is missing or contains errors.
๐บ๏ธ Real World Examples
A hospital uses data quality monitoring to track patient records, ensuring that important information like allergies, medications, and contact details are always correct. If any values are missing or look suspicious, the system alerts staff to review and fix the records, helping prevent medical errors.
A logistics company monitors the data collected from its fleet of delivery trucks, checking for missing GPS coordinates or incorrect delivery times. When issues are detected, the company can quickly investigate and correct the data, making route planning and customer notifications more reliable.
โ FAQ
Why is data quality monitoring important for businesses?
Data quality monitoring helps businesses make decisions based on accurate and reliable information. When data is regularly checked for mistakes or missing pieces, companies can avoid costly errors, improve customer satisfaction, and run their operations more smoothly.
What are some common problems that data quality monitoring can catch?
Data quality monitoring can spot things like missing information, duplicate entries, and values that do not make sense. By finding these issues early, organisations can fix them before they affect reports or day-to-day work.
How often should data quality be checked?
It is best to check data quality regularly, as errors can appear at any time. Some organisations monitor their data daily, while others might do it weekly or monthly, depending on how quickly their data changes and how important it is to their work.

Revenue Management
Revenue management is the process of using data and analytics to predict consumer demand and adjust prices, availability, or sales strategies to maximise income. It is commonly used by businesses that offer perishable goods or services, such as hotels, airlines, or car hire companies, where unsold inventory cannot be stored for future sales. By understanding and anticipating customer behaviour, companies can make informed decisions to sell the right product to the right customer at the right time for the right price.
Quantum Model Scaling
Quantum model scaling refers to the process of making quantum computing models larger and more powerful by increasing the number of quantum bits, or qubits, and enhancing their capabilities. As these models get bigger, they can solve more complex problems and handle more data. However, scaling up quantum models also brings challenges, such as maintaining stability and accuracy as more qubits are added.
Inverse Reinforcement Learning
Inverse Reinforcement Learning (IRL) is a machine learning technique where an algorithm learns what motivates an expert by observing their behaviour, instead of being told directly what to do. Rather than specifying a reward function upfront, IRL tries to infer the underlying goals or rewards that drive the expert's actions. This approach is useful for situations where it is hard to define the right objectives, but easier to recognise good behaviour when we see it.
HR Digital Transformation
HR digital transformation is the process of using digital tools and technology to improve and modernise human resources functions within an organisation. This includes automating repetitive tasks, streamlining recruitment and onboarding, and enhancing employee experience through online platforms. The goal is to make HR processes more efficient, data-driven, and accessible for both employees and managers.
Workflow Automation
Workflow automation is the process of using technology to perform repetitive tasks or processes automatically, without manual intervention. It helps organisations save time, reduce errors, and improve consistency by letting software handle routine steps. Automated workflows can range from simple tasks like sending email notifications to complex processes involving multiple systems and approvals.
