It’s easy to consider a packaging project complete the moment the finished products leave the manufacturing plant. The order has been fulfilled, the goods have arrived, and the product is now on the shelves. From a business perspective, however, this is precisely when one of the most valuable phases of the project begins: evaluating the results.
Data generated during production and market launch can, in fact, provide a more accurate picture of the packaging’s actual performance than any preliminary presentation or concept design. They reveal how consistently the solution could be manufactured, what additional costs arose, whether the schedule was met, and how retail partners and customers responded to it.
Project closure is therefore not merely an administrative formality. Ideally, it serves as a learning opportunity from which marketing, procurement, sales, and manufacturing can all draw useful conclusions.
Why isn't it enough to know that production is complete?
The success of a packaging project cannot be judged solely on whether the correct number of units arrived on time. The final outcome is influenced by numerous factors that may not necessarily be apparent in the proposal or project plan.
For example, production may be completed on time, but with a higher-than-expected scrap rate. It’s also possible that the packaging looks fine, but there are color variations between individual production batches. A new design may reduce raw material costs, but it may require more time and labor in the packaging or logistics process.
The true results of the project, therefore, can only be seen when production, financial, and market data are analyzed together.
Scrap rate: What percentage of products is unusable?
The scrap rate is one of the most fundamental manufacturing metrics, yet it often only comes to the forefront when it is already strikingly high. However, even minor deviations can result in significant costs in high-volume production.
It’s worth asking how many units out of the total production run failed to meet quality requirements, and exactly why they were deemed defective. After all, it makes a difference whether the loss was caused by printing deviations, cutting errors, folding problems, gluing inaccuracies, or defects in the raw materials.
The defect rate should not be evaluated in isolation. It is important to compare it with previous production runs, the average performance of the given technology, and the quality standards agreed upon for the project.
If data is collected consistently, it may become apparent over time which designs, materials, or manufacturing solutions regularly result in greater losses. This can provide a direct basis for optimizing the next project.
Manufacturing variations: What has changed compared to the approved sample?
An approved proof or production sample serves as an important point of reference, but the performance of the final production run must be verified separately.
When the project is completed, it is a good idea to document whether any discrepancies arose:
- compared to the approved colors;
- in the intensity or position of the surface treatment;
- in the precision of cuts, folds, and gluing;
- in the texture, thickness, or shade of the material;
- between individual production lots;
- in the appearance of the various product versions.
A slight color variation may not seem like a significant problem on its own. However, if products from different production batches are placed on the shelf at the same time, the difference can detract from the uniform appearance of the product line.
Documenting production variations is not solely for the purpose of handling complaints. It also helps refine future color references, material selection, proofing procedures, and quality control checkpoints.
Actual cost: How much did the entire project end up costing?
The cost of packaging is often assessed based on the unit price, even though the actual cost is much more complex than that.
Once the project is completed, it is therefore a good idea to compare the original budget with the actual expenses. In addition to raw material and production costs, this may also include the costs of modifications, additional proofs, rush production, repeat shipments, backorders, or remanufacturing.
When analyzing total costs, internal expenses should not be overlooked. If a project required more rounds of approval, coordination, or file corrections than expected, this resulted in additional work for the marketing, procurement, and graphic design teams as well.
So the right question isn't how much the unit price of the packaging was. Rather, it's how much the entire project cost the company, from the initial brief to the product hitting the shelves.
Throughput time: Where was the most time spent?
In addition to the total duration of the project, it is also worth examining the lead times for each phase separately.
How much time elapsed between the handoff of the brief and the first technical feedback? How many days did it take to select materials, create proofs, obtain approval, and complete production? Where did delays occur? At which decision point did you need the most coordination?
This data is particularly important for promotional, seasonal, or rapid product launches. In many cases, it’s not the production itself that causes the delay, but rather an incomplete brief, a graphic file that arrives late, a multi-step approval process, or a technical requirement that turns out to need modification only at the end of the process.
Analyzing lead times can help you create a more realistic project plan, define responsibilities more precisely, and involve the manufacturing partner at the right time.
Retail Feedback: How Did the Packaging Perform in a Real-World Setting?
The final test of the packaging does not take place in the conference room, but in a commercial setting.
It is therefore a good idea to solicit feedback from the sales team, retail partners, and, if possible, the stores themselves. Was the product easy to handle during shelf stocking? Were the different product variants easy to identify? Were the packaging’s stability and size adequate? Did any damage occur during shipping or while being handled in the store?
Feedback from the retail sector can also provide valuable information about visual performance. Did the product stand out from the rest in its category? Was the main message easy to understand? Did the product line present a cohesive look on the shelf? Did the price tag, shelf edge, or placement obscure any important information?
In many cases, these experiences reveal problems that are not visible in either the digital rendering or the production prototype.
Sales Data: Has the packaging's commercial performance improved?
It is difficult to isolate the impact of packaging on sales using a single metric, since sales are influenced by price, promotions, distribution, and numerous other factors. Regardless, comparing data from before and after the project can provide important insights.
For example, the following can be examined:
- changes in sales volume;
- sales per store;
- the ratio of first-time purchases to repeat purchases;
- the results of the promotional period;
- the performance of each package;
- the production rates of the new and old packaging;
- the result of export- or channel-specific versions.
When interpreting the data, it’s not just growth that’s worth looking for. It can also be important to note if a new package design didn’t result in any change, or if one product variant performed significantly better than the others.
Based on sales results, it is possible to assess more accurately which visual, informational, or design solutions are worth carrying forward into future developments.
It is best to examine the data not in isolation, but in the context of their interrelationships
The greatest value of the project wrap-up lies not in compiling individual figures, but in connecting them.
A higher unit price, for example, may be justified if scrap rates have decreased, lead times have been shortened, and there have been fewer quality complaints. A cheaper raw material, on the other hand, does not result in real savings if it leads to more damaged products, heavier packaging, or higher logistics losses.
Similarly, even a spectacular redesign cannot automatically be considered a success if, according to feedback from retailers, the product’s recognizability has deteriorated, or if sales data has not validated the change.
A joint evaluation of marketing, sales, procurement, and manufacturing data helps prevent each department from assessing the project based solely on its own metrics.
What's the best way to wrap up a packaging project?
The best results come from a brief, structured project wrap-up evaluation that involves all relevant areas. It is not necessary to prepare a lengthy report, but it is worth documenting the most important data and lessons learned in writing.
The final evaluation should address the following:
- Which of the original goals were achieved;
- where there were deviations from the plan;
- what manufacturing or quality issues arose;
- how the actual cost and lead time turned out;
- what feedback has been received from retailers;
- What do the initial sales figures show?;
- which solutions are worth keeping or modifying.
It is advisable not only to document these lessons learned but also to incorporate them into the next brief, tender, or manufacturing specification. Without doing so, the same problems could easily resurface in a subsequent product version or campaign packaging.
The end of the project also marks the beginning of the next decision
A packaging project truly creates long-term value when, after its completion, not only the finished product remains, but also the knowledge gained.
The scrap rate, manufacturing variances, actual costs, lead times, retail experiences, and sales results collectively indicate whether the packaging has truly achieved its intended business objectives.
