1 Introduction to Design and the Concept Development Process
What is design?
Depending on the industry we are talking about, design can have many different definitions. Most
generally, “design” is a process for deliberately creating a product to meet a set of needs. Mobile
app development requires both engineering design and product design. Engineering design
focuses on physics, such as speed, mass and other performance measures while product
design also considers user and consumers by asking what the user wants in a product.
Have the students discuss…
1. What is design?
2. Pick an app that you’re familiar with was it designed? Why do you say that? How do you
think it was designed? Who do you think designed it?
3. What products/mobile applications a) work b) do not work and why?
Concept development process
In this chapter, we will focus on concept development and the first two of its three components:
clarifying requirements, concept generation and concept selection.
Figure 1 The design process with the three detailed stages of concept development
The initial concept development process is important because a better design process leads to
a better design outcome. Decisions made during the early stages of design tightly constrain
future options. It is estimated that 70% cost of a product is determined in the first 30% of the
design cycle.

Ways to innovate
There are three main sources of innovation: technology, market and users. Though in reality, all
products are a combination of more than one source.
Technology: Innovation can be achieved through a new form
