The simplicity of use is often at the bottom of the list of specs of a Mobile application. But if you make an effort on this point, it will greatly benefit the users. Here are ten points of ergonomics that should never be overlooked in Mobile App Development.
1. Involve end users
No one knows better than your end user if a mobile application is easy to use, or if its workflow needs to be modified to improve its use. Why IT departments split their efforts into two parts:
- A team that verifies the technical excellence of a mobile application
- A team of end users in charge of verifying ease-of-use and its user-friendliness
No matter the genius used to develop a mobile application, if it is not easy to use, it will not meet the expected success.

2. Stick with business processes and environment
One of the first principles of user-friendliness of a new mobile application or a new technology is its suitability with the process and the working environment for which it is designed. The first intuition may be to look at tablets or mobile phones to think about applications, but a police officer or a taxi driver might prefer a hardened laptop on the ground.
3. Facilitate navigation
Users will not use a mobile application if they have to navigate through three or four menu levels. They will also drop if the application offers a screen loaded with features, but no clue about the workflow to follow to perform daily actions. The prototyping of the application must therefore be carried out with the end users in order to protect themselves from these risks.

4. Design an attractive display
A nice display is an important point for users. But what does “nice” mean for the users? Well in the case of a web interface as a software, it is an interface easy to understand and to use. The aesthetics of the screen (number of images, lines of text, space vacuum but also the layout of all these elements) and the loading time of the displayed elements are all elements that affect users end. They should be able to review and approve your choices before the application is released.
5. Think of recognizable error messages
Most of us have already received error messages such as “Error 207, data incompatibility”, and other enigmatic messages generated from the depths of a programming routine that no end user can understand. As part of your quality assurance process, carefully test the generation of error messages from the application. Error messages must be written in good French, and the end user must know immediately what to do to get by and complete the work in progress.
6. Test thoroughly
To meet tight deadlines, there is often a tendency to reduce testing phases. But more than anything can be, you want to avoid a total crash of the application and a deluge of phone calls from users. To avoid this, spend time on QA (Quality Assurance), and include end users in the process.
The number of media calls you save is well worth your time on testing, and a consistent, predictable and functional application will guarantee users the ease-of-use they require.
7. Think multi-platform software and hardware
Companies are developing applications for a multitude of platforms, reflecting the many devices that their business users use. Therefore, a new application must be as powerful on a desktop, a laptop, and potentially a significant number of Android, iPhone, Blackberry and other systems.
The ability of a device to support a request from an application varies according to each platform. A desktop or laptop computer will be able to host a version richer in features than an application made for Android, iOS, or even a tablet with a smaller computer footprint. We do not do the same thing on a 17-inch screen and a 7-inch screen. For this reason, any application deployed on multiple devices must be designed to be used optimally on each form factor.
8. Design a centralized control and security system
Any application deployed on mobile devices and laptops should contain levels of security and control that allow the DSI to track devices that are lost or misplaced. And if the device can not be located, the ISD should at least use software that can lock the device and disable it.
9. Promote self-completion
If end users administer a customer record, all of the record fields must appear on the screen. This is more convenient: it gives them the ability to check information and change it at a glance. And it is very annoying to enter repetitive data in several fields.
Meet with users during the design of the application to determine the data fields that must be powered automatically by the system. This will avoid frustration, wasted time and typed keys for nothing.
10. Know how to distinguish between complete overhaul and lightweight lifting
IT is often asked to replace old applications that users are unhappy with. And often the expectation is to make the application distinctly different from what it produces, what it looks like, or how it behaves. But there are also cases where users are satisfied with existing applications and simply want a cosmetic facelift of applications without affecting functioning.
