Data Readiness: Why 80% of AI Time is Inventory & Labeling

24/08/2026

The Pain of Misconception: AI is Software, Not Data

Many operations directors I have met believe that deploying AI is like buying a new photocopier. They assume that simply installing software, connecting cameras, or uploading files will result in an immediately smooth-running system capable of making decisions. This is a fatal misconception.

The reality in factories and offices across Vietnam in 2026 is entirely different. Software is merely the shell. The core of every AI project is data. If the input data is garbage, the output will be garbage too, regardless of how expensive the Agentic AI model you use is. During consulting engagements at AIVISION, I often have to pause projects to state plainly: we cannot run AI yet because the data is not ready.

The honest statistic is this: approximately 80% of an AI project's time is not spent on model training or coding. It is spent on inventorying, cleaning, labeling, and establishing governance rules. This is the most tedious, costly, and challenging phase, yet it is precisely where the solution's survival is decided.

Before Running the Model: Inventorying and Assessing Data Readiness

Before discussing buying GPUs or renting cloud services, you must review your data warehouse. Data readiness is not about having a lot of data; it is about having data that is standard-compliant, complete, and consistent. I often see enterprises with terabytes of data scattered everywhere: Excel files from the sales department, outdated server logs, photos taken by mobile phones without titles, or printed reports that have been scanned.

The first step must be a practical inventory. You need to answer: Where is the data located? Who owns it? What is the format? What percentage of the data is missing or inaccurate? A specific example: a component manufacturing plant wanted to use Computer Vision to detect defects. They thought they had enough data. However, upon my inspection, 40% of the defect images were underexposed, 30% were blurry, and only about 10% were clearly labeled with the specific defect type.

If you skip this step, you enter the project with an illusion. When the model starts running, it will produce inaccurate results, causing confusion among the operations team. At that point, you will lose additional time having to start over. The cost of fixing data errors after the model has been trained will be double, or even triple, the cost of preparing it correctly from the start.

During Deployment: Data Labeling and Cleaning

This is the phase I call "the work of miners." Data labeling is not simply drawing a box around an object. It demands absolute accuracy and consistency. In the 2026 context, although automated labeling tools have advanced significantly, humans remain the final checkpoint to ensure quality.

A common issue is inconsistency. One person labels a "scratch" defect with one color, while another uses a different color. Or, images of the same defect type are misinterpreted as two different types due to varying lighting conditions. In such cases, the AI model will "memorize" these errors. The result is a system that reports errors when none exist or overlooks serious defects.

The cleaning process is equally arduous. You must remove duplicate data, handle missing values, and standardize formats. For office data analysis projects, standardizing information fields such as dates, customer names, or product codes is mandatory. A minor difference like "HCM" versus "Ho Chi Minh City" can cause the analysis system to generate two different customer groups, leading to flawed marketing decisions.

Do not hesitate to hire additional staff or use dedicated labeling platforms. Saving money at this stage is a false economy. I often advise directors: treat labeling as a production process, requiring clear input standards, quality control (QC) procedures, and defined outputs.

After Live Deployment: Data Governance and Quality Maintenance

Many believe that once the model runs stably, the project is over. This is a mistaken viewpoint. Data is a living entity; it constantly evolves over time. Production processes change, customer behaviors shift, and new data is generated daily. Without Data Governance, model quality will gradually degrade over time, a phenomenon known as "model drift".

Data governance is not just about storage. It involves establishing regulations on who can access, who can modify, how to ensure security, and how to maintain consistency when new data is added. You need a mechanism to continuously collect feedback from reality. For example, if the Computer Vision system misses a new type of defect, the operator must be able to easily report it, and that image must be fed into the labeling process to retrain the model.

At AIVISION, we often establish automated processes to monitor input data quality. If new data does not meet standards, the system will reject it or issue an immediate warning rather than allowing the model to learn from dirty data. This is the only way to ensure your AI operates sustainably in the long term. Data Governance is not a one-time project; it is an operational culture.

Hard-Earned Lessons: Don't Let Data Break Your Project

I have witnessed numerous AI projects fail because investors were too hasty. Wanting immediate results, they skipped inventory and cleaning steps. Consequently, the model ran for a few weeks before producing inaccurate results, eroding employee trust. Only then did they remember the data issue. But it was too late to fix it effectively.

Conversely, successful enterprises are those that dedicate time to Data Readiness. They view data preparation as a mandatory investment. They build rigorous labeling processes and establish data governance rules from day one. They understand that AI is only as intelligent as the data you provide it.

When you accept that 80% of the time will be spent on data processing, you will no longer be shocked when a project takes longer. You will allocate budget and personnel more reasonably. You will have a truly useful AI system, not an expensive decorative item. Remember, in the world of AI, data is gold, but only when it is mined and processed correctly.

Frequently Asked Questions

Can we skip the data cleaning step to save time?

No. Skipping the cleaning step will lead to the model learning incorrectly, resulting in flawed decisions and costing many times more to fix later. Data quality directly determines the quality of the AI.

What percentage of the budget is typically allocated to data labeling?

This figure varies significantly depending on the project, but on average, it can account for 30% to 50% of total deployment costs. For projects requiring high precision, such as healthcare or production safety, this ratio can be even higher.

Is Data Governance necessary for small businesses?

Yes. Even for small enterprises, without basic data management rules, the system will quickly become chaotic as it scales. Data Governance ensures consistency and security, serving as the foundation for sustainable growth.
