Saving Time Developing Mobile Software for Handheld PDAs

It is important to recognize that mobile software applications for handheld PDAs are not just developed by 1 person in a dark room with a computer. The business unit manager can order a mobile software application to be developed, but someone must design it, develop it, test it and approve it. Do you really want the programmer to complete the entire application on his/her own, or do you want a person who understands the business to be involved? Here are some considerations:

1. Do you want the mobile software application to look exactly like the paper form in use today? If you don't specify differently, the programmer may design it to look like a small piece of paper on a mobile handheld PDA.


2. Do you want the programmer to dictate your business process, or do you want to tell the programmer how the business process should work?


3. Do you want the programmer to tell the field workers how, when and where they should sync the mobile application, or do you want the business users to tell the programmer.


4. Do you want the programmer to select the mobile handheld PDAs, or do you want the business unit to describe their requirements to the programmer?


5. Do you want the programmer to tell the business unit when the mobile software application is complete and final, or do you want to test it and approve it?

Most of these questions have obvious answers. The business unit, the organization that will benefit or suffer from the mobile application, needs to have active input into the design, development, testing, deployment and support of the application. It is not a 1 programmer job.

The problem many development projects suffer from is this active involvement was not anticipated or planned, therefore, it either does not happen or comes as an inconvenient surprise. However, you have now been warned in advance so this will not happen on your project, right?

You Should Not Develop a Mobile Application - Just Because You Can

We often receive calls from software developers asking about our mobile software development environment. The developers often ask the question, "Why should I use your development platform when I can develop my own mobile software application for handheld PDAs?" That is a good and fair question. I will usually follow their questions with my own:

1. How many mobile software applications have you already designed, developed, deployed and supported successfully for handheld PDAs? Is your employer comfortable with having you learn on the job or are they risk adverse? Are they willing to be patient with your learning curve? If it takes you 4 months longer to develop your own, does the business suffer?
2. Have you created a full synchronization engine successfully in the past? This is very complicated and software companies like MobileDataforce have spent years optimizing these. What are the chances you will get it right and optimized on the very first project?
3. Do you have experience developing and configuring a variety of connectivity options such as cradle sync, wireless sync, satellite sync, bluetooth, etc.? Does the business manager know which one is needed in every case? Should you develop one, or develop multiple methods? Are the business requirements likely to change in the next 3 years?
4. Have you developed a full database integration manager for mobile solutions? Do you need an API or will your DBA allow you to directly populate the database? If you can directly populate the database, then the data better be validated in the mobile software application on the handheld pc. Did you set aside time for that?
5. Do you have experience designing scalable and reliable mobile applications? This is simply an experience thing. You don't know what you don't know.
6. Do you have support for a Pocket PC 2003, Win CE, Microsoft Mobile 5 & 6? How are you going to upgrade and support next year's mobile OS from Microsoft? Is this built into your project plan and budget?
7. Have you developed mobile applications that run on a large variety of different mobile handheld devices? This takes a lot of work and thought. Every week new mobile handheld devices are being delivered with new technologies and add-on components. The device selected today, will likely not be available next year at this time. How do you keep current?
8. Do you have experience developing interfaces for third party hardware? Mobile applications often need additional third party technology integration like bar code scanners, RFID, GPS, Digital Cameras, etc.
9. Have you thought through and developed dashboards for managing mobile application security, users, applications publishing, etc?
10. Do you have a development environment set up exclusively for mobile applications development that may include short-cuts, libraries, screen designs and scripts?
11. Do you have experience creating a helpdesk dashboard for sync logs, users, applications, device management, etc.?

Most often the developer was only interested in creating the screens for the mobile application, not a complete mobile application platform and support system. They had not considered the full end-to-end solution requirements when volunteering to develop a mobile handheld application.

Now the NMS 5000 Rugged Tablet PC I Like!

I came across this ruggedized tablet pc today and am a fan. I love the right hand buttons for short-cuts. Perhaps because I am right handed - sorry left handers. Many field data collection projects involve maps, blueprints and other files that benefit from a larger screen in a rugged case.

NMS 5000

The NMS 5000 provides data collection technology ideal in several applications including field service, military, industrial / manufacturing, medical, parking management, public safety, utility services and retail. More...

Chossing Between a Rugged PDA or Industrial Grade Handheld?

My sales team is asked hourly for recommendations for mobile handheld computers, smartphones and PDAs. The customer is always looking for the most cost effective solution. Cost effective must include value, reliability, usability, flexibility, expandability and much more - the total cost of ownership. There is a document you can download here that lists all the questions you need to ask before making the purchase.

I was reading about the industrial grade handheld PDA M3 today and their description points to some of the rugged features that users need to consider.

M3 Industrial PDA M3’s rugged design and IP54-rated sealing ensures continued use and uptime by protecting against dust, moisture and extreme temperatures (-20°C ~ 50°C), And, whether working inside or out, it has a drop spec of 1.5m to concrete across vast temperature ranges, reducing equipment and maintenance costs.More...

A lot of your decision needs to be based upon what kind of mobile software application you are going to use and what operating system it requires. Do you need a large screen to read drawings, blueprints and maps, or a simple data form?
