Vijay Thea – Learning Launch

Challenge

I am a team member with four of my friends in a university course which is Design of Experiments.  Learning Launch tool was used to make an experiment project about testing tea thermos. In most  Saudi occasion one of the important things that must be served is tea. in addition, serving tea is  considered as traditional welcome to the guests in most Arab cultures. Therefore, one of the main  Property of tea is that it should be served hot, so when the tea becomes cold or even warm, it loses  its value. As we can notice that on most occasion, they prepare tea before the occasion time starts,  usually poor thermos cannot maintain the temperature of the tea which disturb the enjoyment and  give bad impression to the guests.

Selection

We selected this approach as it is the best approach to make our project. Simply we are going to make  some experiments on some tea thermoses, and we will make some statistical calculations and  hypothesis. Learning Launch is a very effective tool to use in such a project as it will show all the results  clearly.

Application

The main idea of this experiment as we mentioned previously is to find the optimal factors treatment  combination that increase the ability to maintain the tea temperature in the tea pot as longest time  as possible. So, to find what we are looking for, we planned to perform the experiment as follow: First  we will heat up the tea until it's temperature reaches 90°C then we will put it in the tea pot. After  putting the tea in the tea pot we will measure the tea temperature after one hour and write down it.  a stopwatch and a digital thermometer both are going to be used in this experiment to determine the  exact time and temperature. the experiment is going to be repeated with various combinations of the  three factors that we have.    An experiment has many factors that give result. This result is a goal that has been set since the  beginning of the experiment. In this study on the Tea Pot, we seek to find the optimal factors  treatment combination that increase the ability to maintain the tea temperature in the Tea Pot as  longest time as possible.    The vary of factors we will measure it by the output of the experiment (response variable) which is  the ability that the Tea Pot can maintain the tea temperature. We will use the temperature in (Celsius)  as a unit of measuring our response. So, we can conclude from the response variable the effect of our

factors on the maintainability of tea temperature in the Tea Pot. We will take only one reading per  response for each run.    It is important to choose the appropriate Replications for each experiment. Where more repetition  will lead to a significant result in the experiment. This is done by repeating the experiment with the  same exact combination of factors more than once. Thus, we choose three as a number of replicates,  as it reduces the pure experimental error that comes from uncontrollable factors and it validates the  experiment. Furthermore, as a result it will require more effort, but the accuracy of the data is more  important in our case.

Table 3: Data Sheet

in our experiment there are 36 runs and 36 observations also the number of hypotheses will equal  number of effects. Also, the table consist all the numbers of parameters that needed during the  experiment such as the number of factors and levels, numbers of replicates, and so on.

A: kind of material (Steel “S”, Plastic “P”).  B: the amount of tea (0.5,1.0,1.5 liters).  C: type of tea (Tea Powder ”TP”, Tea Bags” TB’).

Insight

By applying this method, we got our hypothesis very easily and effectively as this approach helped us  clearly set up our learning goals. By using this tool, we learned some new skills such as improving the  workflow to ease the process, structure our work easily and so much more. In addition, we would  like to share our hypothesis that we got.

Approach

Actually, we already gone through several design thinking tools and actually this is the appropriate  one that was fit to our challenge. In future projects another tool maybe used like mind mapping  which is a very powerful tool that can be used to visualize ideas. Moreover, story telling is a great  tool to use in a lot of future projects.
