Evaluation and selection

Using an evaluation matrix, the derived ideas were evaluated and high scoring ideas were further elaborated. Following were the criteria to evaluate the derived ideas:

1. Newness 2. Ability to solve the problem 3. Practical 4. Profitable 5. Achievable using my skills 6. The potential for early users 7. Passion factor (I really love it!)

This allowed me to come up with our solution which was formed via combining two ideas which were ‘virtual cupboard’ which Linked the donations, rental, selling and exchange sites to our inventory. The next section of the developed solution was ‘spend4joy’ which try to plot the user’s expenses and their relationship with joy on a quadrant for clear communication/feedback. The result was a graph as seen in Figure 9.

Well-used

Underspend Overspend

Donate Unused

Exchange

Rent DIY Sell

Figure 10: Personalized interactive data visualization which shows the individual purchase of items and their perceived enjoyment that was brought to the user against how much the person spent for said item.

The graph in figure 10 explains 3 things. First of which is the Y-axis which indicates the level of user satisfaction over said purchase in each insight category. Next, the X-axis indicates the perceive spending of each insight category. Being able to see items bounded by both of these axes gives us an insight to our past spending and how worth it is it to spend on said category. Lastly, the graph also enables us to set target goals for the items which fall under the category of unused in order to derive more value from said purchases via renting, selling or exchanging. This idea was refined and taken forward for prototyping.
