The Truth about Right First Time (RFT)

Updated: Oct 13, 2019

Right First Time (RFT) is basically completing a task right the first time. That part is clear, but look deeper into the true driving force behind it. To better understand RFT, we have to first look at what it isn’t.

When a task is completed, in this example a manufacturing process, it has to go through an approval or quality inspection prior to its release. This stage ensures that what the company is promising their customer is delivered each and every time. If at the point of inspection, the required quality standard is not met, the process often has the product sent back to production for correction if possible. This creates a back-and-forth flow in the process. Waste increases as a result. Overall, you have increased cost and time for the production investment. RFT was inspired to assist in this quality challenge and streamline the process for a higher return.

Whether you are in production of a good or service, your process has a timeline. It has a beginning, middle, end, and probably a few other steps in between. In order to make you and/or your team as efficient as possible, this process needs to be lean. And don’t forget, the leanness of your process has to gradually keep increasing in order to stay competitive. Ideally you don’t waste your time on non-value adding activities and your overall efficiency always improves. That’s where RFT can come into play. The less times you must repeat work, the lower the cost. The lower the cost, the higher the end profit.

Realizing the truth – we can’t always get it right the first time. When you have a process that utilizes people, you’re going to have errors. This happens even with robotics, but for this article we’re going to focus on the human element. I’m not an engineer in robotics, but for people, they can be just as challenging and often more complex. With getting it RFT, we can’t strain on writing a date correctly without making an error like in current Good Manufacturing Practices (cGMP). When a part of the process must be anywhere close to artistic as a paint stroke, you will lose the uniformity throughout said process.

Step one – Aside from collecting the back-end data, get it under control. Focus on the initial entry/activity ... Yes ... but also focus on your next line of defense. Think of it like a series of rings. Your first line of defense is the person performing the activity. They need to have the focus and mindfulness to perform it correctly. The next line of defense, or ring, can be the person performing their check or check-by. The next could be the supervisor’s review, depending on your process. This intention is to line up your defenses to better control the produced product prior to Quality’s initial inspection.

This is not an end-all. This is needed to get Control of a current process while you make the True needed changes. Focusing on the output will in most cases not improve your process. We need to focus on the input.

Taking the cGMP documentation example, let’s look at the input opportunities. When looking at your process, ask yourself, “Is this step redundant? Do we need to record this step? How can we simplify this entry?” Combing through your process with questions like these is a good start for your RFT direction.

Removing redundant steps allows less entries. Less entries allow less opportunities to make errors and so forth.

Simplifying an entry or step can come in an endless amount of ways. One idea can be when measurements are recorded. By designating the measurement (i.e.: seconds, °C, RPM) you remove unneeded entries allowing the operator to be responsible for only the numerical entry.

Another way to simplify the entry would be through combining multiple entries into a single entry. If a task being performed has two entries and those entries can only be performed at the same time, then there could be an opportunity to combine the entries into just one instead of multiple entries. Less entries easily leads to less opportunities to make errors.

The flow of the entries can make or break your process’ rhythm. If an entry is not following the appropriate preceding entry, you create back-and-forth movement within the documentation which will ultimately result in increased errors.

There is also the back end. The back end can be tracking of the mistakes and the data behind them such as who made the mistake, frequency of the error, and where in the process the mistakes are made. This data is just as important as the front end work by giving higher visibility on your overall gaps. If RFT is your goal, then ensure that this information is being collected as it will ultimately impact the direction of your efforts.

Those were just a few ideas to get you going in the right direction for RFT. Spaghetti chart your process and see if it makes sense. Make your process as clean and simple as possible. Remove what isn’t needed and only keep the bare essentials. Be mindful of falling in the over-inspection trap. Inspections at too many locations is simply padding a poor process. The process should be evaluated to make it more robust and effective. RFT is steady steps in the right direction.
