Over-engineering - design for a smarter world

On many occasions I became irritated as the user of a product when noticing that the product was designed to be smarter than me. - Just have a look at many software products we are using in daily life, or at user interfaces from coffee machines, or at text completion on a smartphone, ...

Now, these days I bumped into this funny video about testing the sophisticated design of a children's play. I feel so sorry for the designer. It must be so painful for her (yes, it's an actor, but having been in the role of designers, testers, and end users, I have seen this situation many times).

It's funny to watch this scene, but imagine the scene while designing the play!

The designer get's all these fancy, and sophisticated requirements and use cases from some innovator, a product manager, or just from potential customers of the product. The tell him thousands of things what feature the product needs to exhibit.

In development, engineers think about these requirements about features and ask themselves, what problem the end user is going to solve with the solution. - Confusion arrises.

Often - I have seen this so many times - a dialog between designers and product managers evolves.

- Engineer: "what do you want to achieve with these elements of different form and shape"

- Product marketeer: "don't ask questions, just implement it - that's what you are paid for. Otherwise I can not sell that product."

- Engineer: "but it does not make sense - can we talk to some end customers"

- Product manager: "just do it! You are jeopardising my bonus payments!"

- ...

And so on, until the engineer does what he is asked for at the level of features. That's what he is paid for.

The result: yes, we know it!

- End user: "what the f... these stupid designers and engineers, have they ever been talking to a potential user?"

The moral of the story - you do know all of these books about user centric design, about lean business build up, about most uncertain assumption testing, ...!

A gardeners struggle - the soil bag

During spring and early summer, in the time of the year when plants start growing, everything is sprouting, nature in bloom, people start working in their gardens. According to statistics a habit two thirds of people in Switzerland share (reference).
The current COVID measures seem to drive this statistics even more in favor of sales of gardening supplies (reference).

Everybody is buying soil in various quantities. Many different flavors of soil. And, all packaged in laminated plastic bags. Bags, usually 80 - 100cm long, 40cm wide, and 8cm thick. Filled with premium soil at volumes of few liters for plants on terraces, up to 50 liters of garden soil for big projects. In any case, the package has a certain weight.

I never understood this packaging format! Why would you choose such packaging?
Obviously the responsible designers for these products have never been working in the garden. Or, they are extremely resilient to handling inconvenient products.

Every time I have to carry such a package I get upset.
If I grab the package with two hands on one of the short ends, it is difficult to carry the package and it risks constantly to slip out of my fingers.
If I grab the package with my hands along the longer dimension, then the package - given its weight - is bending through, slips out of my hands, and falls down on the ground.
If I grab it in the middle along the shorter dimension, it is bending through equally and it becomes difficult to carry.

When then loading the packages into the car, the next struggle starts. The dimensions of soil packages are not really fit for purpose. Obviously I need to pile the packages into the trunk of my car. And this is not an easy job. Virtually impossible if you are not Olympic weight lifter. Unloading is the same struggle in reverse order.

And then when ripping them open and trying to dose the amount of soil to be scattered into the plant bed. As soon as a certain amount of soil is missing in the package, the laminated bag becomes unstable. If not emptying the entire bag at once it becomes difficult to handle the package in controlled manner.
  
My practical experience with such packages is repeatably negative leading to higher levels of frustration.

How could one decide for this packaging format? What have been the requirements to come up with such package design?

One reason might be the possibility to pile many packages on a standard palette for transport and storage. 

Obviously an important argument and requirement. Efficient transport and storage is essential for a economically viable product. But, does it need to come at the price of modest customer experience and usability.


What I wonder is, if this packaging format has ever been put at a test with real day to day users.

Apart from the described scenarios above, many users can barely carry such packages given its dimensions and weight. I don’t want to know to how many serious back problems of people struggling to handle such packages the lack of customer centricity can lead.

Another interesting observation is the fact, that all manufacturers of packaged soil products use the exactly same packaging design. Why is that?

I can imagine several hypothetical reasons.
  1. Nobody cares about the user, given the fact that there is no alternative and people still are buying.
  2. Every producer is copy pasting from his competitor. Nobody is searching for differentiation. Nobody believes in consumers paying a premium for improved usability.
  3. Even tough there are many different vendors and brands there might be only very few producers of soil.
  4. There is only one serious manufacturer of respective packaging and filling systems. This would explain why there is almost no alternatively packaged products available.
  5. The packaging design experts are only doing me-too. With complete lack of usability exercises or user research.
  6. The cost requirements for packaging of garden and plant soil are so incredibly low that no other packaging is affordable.
There might be many more reasons ... And, are we as consumers willing to accept these?
What price would we be willing to pay for a better packaging design allowing acceptable handling of soil bags in the shopping, the transport, and use process?

How would a better package look like? What would be the features of a more ideal soil bag? Is there a format that could meet most of above requirements?

Some internet research gives already some hints. There might still be some products which are packaged in other format. Formats which might be more convenient to handle.

The package here to the right for sure has several advantages over the standard laminated bags. 

The handle on the top - foldable for being able to staple them on a palette (transport and storage requirements) - seems key to me. Only with a handle one can carry packages in a serious way. And depending on other dimensions and weight of the package it would even allow me to carry two packages at once, one with each hand. A much more balanced and more efficient way of carrying them.

If the package is less of a slim long bag, but more of a cuboid shape the usability of carrying them by the handle on the top becomes even better. A cuboid shape also fulfills the requirements for stapling the packages on a palette. They could be better organized into the trunk of a car, and could be better stored around the garden.

Also when using them in the garden; cutting the cuboid package open at one corner would allow to much more keep the shape of the package and dosing soil for use.

So, pretty simple and obvious to come up with a packaging format that might lead to much better customer acceptance. 
I am not a packaging expert. And I can well imagine that a packaging system for a cuboid product with a handle requires to manage some more degrees of freedom. But, given the quantities of soil being produced and sold in that business, and given the fact that such packaging and filling can be highly automated I would assume there is a case for such scenario. I could well imagine that going for such packaging could be a differentiating factor.

If you had the choice? Which package would you buy? And, would you pay a price for more convenience?

The right conclusions

To design ergonomic products, or to provide a best in class user experience, the designers and researchers have to draw the right conclusions.

Conclusions based on evidence, based on data, based on analytics.

How to come up with the data and evidence leading towards respective conclusions and design decisions.

It is important to design some good experiments and take control over how and from what sample the data and evidence is acquired.

Otherwise, data could infer some conclusions as described on the right. - The perfect explanation for the extinction of dinosaurs. - Same might apply with babies and storks...
