Paola Appendini, Mars
In an agile approach, packaging is part of a holistic innovation system rather than an afterthought. Instead of investing large amounts of time building the “perfect” concept before testing it, agile innovation breaks development into small, iterative cycles that prioritize rapid learning. Agile processes rely on fast prototyping and experimentation, allowing teams to identify risks and optimize ideas early, long before final investment decisions are made.
This approach is transforming how teams pursue packaging solutions. For example, a team exploring a refillable liquid product might start with a simple, low-fidelity bottle prototype and a small number of consumers in an informal setting. This could be enough to understand how easily these consumers can refill it, trust the closure, or store the container. This early learning increases speed, reduces risk, and helps teams optimize quickly before moving into the next iteration.
Use hypotheses to learn and iterate
At the core of agile innovation is the hypothesis, a clear statement about what is believed to be true and must be validated. In packaging, most hypotheses relate to desirability (consumers want it), viability (it can sell), or feasibility (it can be made). For example:
- “We believe consumers will prefer a resealable pouch because it reduces mess and improves portion control.”
- “We believe a glass-like PET structure will create a premium perception while delivering the sustainability benefits of lightweight plastic.”
Each hypothesis is measurable and tied to a consumer, technical, or business outcome and is framed in a way that when tested, it can yield clear decision-making results.
Not all hypotheses are equally important. Some can be disproved without derailing a project—such as assumptions about aesthetic preference, minor convenience features, or on-pack messaging. Examples include:
- “We believe placing the recyclability logo on the front panel will increase purchase intent.”
- “We believe including a tear-notch will improve the opening experience.” If consumers don’t care, the notch can be removed and the product still functions and sells.”
Noncritical hypotheses help refine a solution but do not dictate whether the package innovation should be halted.
Killer hypotheses
Killer hypotheses are those that, if proven false, undermine the success of the project. These assumptions must be tested early to avoid expensive misalignment or late-stage failure. Killer hypotheses guide essential learning and help teams determine whether a concept is viable at all—not just what needs refinement.
For example, for a mono-material flow wrap, a killer feasibility hypothesis might be: “We believe the film will maintain integrity through the supply chain without increasing damage rates.” If the material cannot perform, the project cannot move forward, even if consumers love the idea or sustainability benefits meet goals.
Killer hypotheses often stem from foundational questions that teams cannot initially answer with confidence, such as:
- Will consumers adopt the new behavior required by the packaging (e.g., returning a reusable pack for refill)?
- Can manufacturing lines reliably run the new material at scale (e.g., a new paper-based film requiring equipment upgrades the business cannot support)?
If the answer to these questions is “no,” confidence decreases immediately. By surfacing these risks early, killer hypotheses empower teams to validate or eliminate major assumptions before committing significant resources.
A hypothesis is not a killer hypothesis if failing it:
- does not undermine the business model
- does not break manufacturability or supply-chain feasibility
- does not introduce safety or compliance issues
- does not require major structural redesign
- does not change the required core consumer behavior
Why killer hypotheses matter
Ultimately, the case for killer hypotheses is the case for disciplined, transparent, insight-driven innovation. Agile innovation accelerates learning, but killer hypotheses ensure the learning focuses on the factors that truly determine success. Packaging innovation rarely fails due to a lack of ideas, it fails because critical assumptions go untested until it is too late.
By identifying and validating killer hypotheses early, organizations can build packaging that delights consumers and gives leaders, retailers, and supply-chain partners the confidence needed to bring successful innovations to market.
