Reflection on Microsoft Excel

            My next reflection is on Microsoft Excel, a spreadsheet-software. Excel is very useful to a variety of different types of people, making it meet the principle of equitable use. For example, Excel can be useful to teachers, students, business workers, moms and dads on a budget, etc.  Excel also has a wide range of flexibility in use, with its range of templates, tools, and uses. For instance, Excel can create simple spreadsheets, graphs, tables and can also generate percentages, formulas, and insert SmartArt. The rows and columns also are re-sizable for whatever the users wanted size is. Excel also has simple and intuitive use since the design is easy to use and simple to understand. There is also a “review” tool option to provide effective feedback after task completion. Excel also meets the perceptible information design, due to its use of different modes (pictorial and printed). The tolerance for error principle is also used in Excel since it has an edit tool, called “undo”.  Excel also has a low physical effort, meaning it is not too difficult to use and does not require much effort to understand. It provides an easy tool to click on to save the document, can easily differentiate columns with multiple colors, and can even transform written information into a graph or table form (with the push of only a couple keys). This type of technology does not meet the size and space approach and use design since it does not require any additional components (in a physical way) to accommodate to a user’s body size, posture, mobility, etc.
