In an earlier sprint, the concept of developing a Binder Jetting System was made. The concept went onto further development, which a CAD model was drafted.
With the arrival of the EVEBOT printpen, system analysis towards the EVEBOT system suggested many technical issues with the core functionality of the Binder Jetting System such as:
Decision was that the system is unacceptable and were to return to a preceding stage. Meaning going back to exploratory research surrounding food printing with the lessons learns from the previous sprint

A concept was being explored: Replacing sticker labels on fruits by using the EVEVBOT printpen instead. The business case of the concept is focused on sustainability.
A sketch of the concept was made and conveyed to the product owner. Unfortunately, the business case was proven to be weak, as there can be better alternatives such as using disposable stickers and as such the system's core business aspect of sustainability can be misleading resulting in "Greenwashing".
Decision was that due to the business aspect being unacceptable, the system is unacceptable to carry on and was to return to the preceding stage, which is exploratory research again.

A problem was being identified and looked upon: The EVEBOT printpen has issues printing on curved surfaces.
This problem gave rise to a concept. A universal curved surface printer that could print on any curved surface.
Unfortunately, this idea was scrapped quickly. There were many technical challenges to overcome and no concrete business case can be made with the system.
Decision was the system is unacceptable to carry on and was to return to the preceding stage, which is exploratory research again.

The previous identified problem was looked upon again and it gave rise to another concept: printing on the curve surface of cakes without touching the cake.
A business case for the system can be found as there is a potential that pastry chefs can use the system to aid printing of designs on the side of cakes.
The initial design of the system is driven by research online, which gave insights to the sizes of cakes and the process of cake making.
The concept was conveyed to the product owner who suggested seeking input from external stakeholders for more development of the system.

More information was gathered through contacting directly with bakers. The design was further refined to cater to the needs of the cake making industry.
The design of the system was further developed to cater for cakes of different heights ranging from 3 inches to 7 inches.
