1. Design brief
Defining the goal
My goal of this unit is to educate a certain age group of people on the health
benefits of a particular technology by making a video. My chosen technology is
percutaneous coronary intervention. I need to make a video which will be attractive to my
target audience, while it can describe the applications of the percutaneous coronary
intervention and how this technology will benefit people. I also need to consider how to
make a good video. For achieving my goal, I should do lots of researches on my chosen
technology, and how it is beneficial to a certain group of people. Moreover, I should look for
some examples of similar products so that I can identify necessary and desirable
characteristics. I will also do some studies on how to make a good video and what software
that i am going to use, since that my goal is to make a video introducing my chosen
technology to educate a target audience.
Target audience
My target audience will be the people above forty years old. The people at this
certain age group have higher risks to gain heart diseases and coronary diseases, such as
acute myocardial infarction. My chosen technology, percutaneous coronary intervention is
particularly beneficial to the people who have those diseases. I will introduce this technology
to the people above forty years old, educating them about what a percutaneous coronary
intervention is, how it works, how it will benefit them and what their advantages compared
to the other technologies using to solve the same type of problem. I choose this group of
people to be my target audience because I think the information in my product is useful for
them, and they may find it interesting that what I am going to introduce them.
Major constraints
There are many different constraints that will limit me on design. I should take
care of laws (such as copy rights), time I will have to make the product, the software I use
and my skills to use this software, my knowledge of the technology that I am going to
introduce, and many other things. I think the major constraints for me to design the product
are time and knowledge.
