Handheld Computer Considerations



There are a lot of good handheld computers available and some bad ones. I will leave the bad ones for a future discussion and focus on some of the points to consider when selecting good handheld hardware.

  1. What environment will you be using the handheld computer in - is it hot, cold, wet, dusty or filled with explosive vapors? Is it a clean office environment, or a rugged out-of-doors environment?
  2. Is your software application focused exclusively on bar code scanning, RFID reading, GPS, or do you need a multi-purpose device?
  3. Will the hardware configuration ever need to be changed? Some handhelds can be configured at will, others are locked and can only be used with the original configuration.
  4. What hardware does your selected software require?
  5. Will the battery last long enough to accomplish your work? Do you need back-up batteries? Can you use batteries purchased at the local market, or are they vendor specific?
  6. What is your budget? What does the value of using a handheld computer justify spending? Do you have enough budget to purchase the software and hardware you need? Does your budget only allow for low cost consumer devices? How many replacements cover the cost of a ruggedized handheld?
  7. How do you replace broken devices? Can you get a replacement in 24 hours, or must you wait on the slow-boat-from-China?
  8. What kind of support contracts and warranties are available?
  9. How long will you new handheld computer be supported, serviced and manufactured by the vendor. Is it near end of life and being discounted for a reason?
  10. Can you upgrade the operating system when Microsoft releases a new version of their mobile operating system?
  11. Can you use standard laptop data cards in the handheld, or do you need to pay for high priced vendor specific cards?
  12. Can you view the screen effectively in the sunlight?
  13. Does the bar code scanner work effectively in real-world environment? Some scanners can not scan effectively through glass or plastic.
  14. Is the size and weight of the handheld appropriate for the user and environment?
  15. Can your handheld computer support all the add-ons you require at the same time? Some devices can only support a specific number of add-on components so you are forced to choose. Some can not support both a GPS and a data card at the same time. Some devices can not support both a bar code scanner and a GPS add-on. This is an important consideration.
  16. Do you need only a touch screen and navigation pad, or a number pad or a full QWERTY keyboard? This is very important for user acceptance.
  17. Is the handheld device also going to be used as a phone? Is a 2 pound industrial grade handheld really a usable phone?
  18. Does your low cost consumer grade PDA need a rugged case like the ones Otterbox sells?
  19. If you only have a budget for a low cost device, does it support the battery life and add-on components you require?
  20. How will the device be transported around a job site? Will it strap to a belt, swing from a shoulder strap, sit in a holster or be mounted to the dashboard of your truck? Does your device support your chosen method?
  21. Where is the closest inventory of the handheld computers? Where is the closest repair depot?
  22. Will your vendor loan you a device on trial?
  23. How will your handheld computer send data back to the office - cradle sync, WiFi, bluetooth, GPRS/GSM, CDMA?
  24. What size screen do you need? Some devices like the Jett-Eye have a "landscape view" others a "portrait view" many have different sized screens. What do you require?
  25. Do you need an integrated digital camera? Do you need a low or high resolution camera and does your device support it?
  26. Does a refurbished device from Ryzex make better sense that a new device?
  27. Where is your vendor's office? Are they in the neighborhood or on the other side of the planet? Does their location offer you the support and attention you deserve?
  28. Does your handheld computer run on the same operating system that your software solutions require?
  29. Does your handheld computer come with a pistol grip or other straps that help you avoid dropping it?
  30. Can you comfortably hold the device in your handheld and complete the required job? Some devices have scanners on the side, on the end or underneath.
  31. Can you effectively view the data you need? Some jobs simply require a full keyboard and a full screen for viewing large CAD files or Maps. Does your screen size match your requirements?

RAM Mounts for Mobile and Handheld PDAs

Tools, Parts & Mobile Work Order Solutions on Handheld PDAs


We have had several requests recently to combine mobile work order solutions with inventory and asset tracking applications for use on mobile handheld PDAs. This is not unusual, it just points out the fact that companies are recognizing a great deal of value from mobilizing business processes. Here is an example:

The company wants to track any employees that enter the stockroom where both inventory and tools are kept, and track anything that is removed by them. They would do this by matching the employee's ID cards, with the customer's work order and any inventory or tools that are used on the work order.

This solution would better control the use of tools and inventory, and ensure they are appropriately billed to the customer's work order. This system would provide the following ROI:
  1. Reduce missing inventory
  2. Bill the customer appropriately for inventory usage
  3. Bill the customer appropriately for the use of tools
  4. Track the tools and who has them (asset tracking)
  5. Assign inventory and tools to an employee for accountability
  6. Reduce the labor needed to manage inventory, billing, and assets

The Latest Information on Appforge

After losing over $24 million since 2001 Appforge closes and sells assets to Oracle. Here are a number of additional articles and blogs on the subject:

Paintless Dent Repair & Handheld PDA Solutions

MobileDataforce has become one of the leading suppliers of mobile handheld PDA software applications to the Paintless Dent Repair industry (PDR). A few years ago I would not have guessed this would turn out to be such a dynamic and growing market for us.

Why are companies involved in the PDR industry using mobile handheld PDA solutions for field services? Here are a few of the business issues that mobile solutions address:

  • Avoid duplicate billings - when a car is brought into inventory, the VIN is scanned using a bar code scanner, this creates a new and unique record in the mobile software application that can be used to uniquely identify the vehicle and to assign inspections, work orders and invoices to it. This avoids duplicate billings for the same vehicle which causes the dealership to question your integrity.
  • Avoid double entry of data - data should only be entered once. Data should be entered at the "point-of-work" and then synchronized wirelessly directly with the office accounting system. When you use a paper form based system, the staff in the field must fill it out, fax or deliver it to the office where another staff member must decipher it, analyze it, complete it, and then re-type it into a computer system. This is a huge and unnecessary cost and prevents many franchisers from scaling up in size.
  • Managers and staff need to know what is happening in the field. Mobile handheld solutions that are wirelessly synchronized with the office computer system can be updating time sheets, production sheets, inventory, employee data, work schedules, sales, customer information, invoices, inventory etc. all day long. This provides management with near real-time visibility into their operations. This is how active, mobile managers stay in touch with their distributed operations.
  • Many of our PDR customers are competing with other companies for an auto dealer's business. Being able to show the manager of the auto dealership how your operations are mobilized with rugged handheld computers, wirelessly synchronized with the central office and capable of printing invoices and work orders directly from in the field is very impressive. It shows a level of sophistication and operational excellence missing with many PDR operations.

Thoughts on the Business of Mobile Handheld PDA Software Development

Software and IT Consultants that wish to offer general mobile software development services and mobile handheld PDA solutions to a broad market have the following important business management questions to consider:

  • how do you achieve economies of scale (get better and faster over time to increase profitability)
  • how do you manage risks (from many new and custom development projects)
  • how do you develop in-house expertise in a broad windows mobile market with a large number of different mobile business processes
  • how do you develop all the appropriate technology skills necessary to deliver a wide variety of applications using different synchronization, security, integration, database, business process and connectivity options in your mobile software
  • how do you develop a complete quality assurance plan for every new custom mobile software application (make sure you include this time in your proposal)
  • how do you efficiently test and de-bug a large number of custom mobile applications
  • how do you document how each customized software application works (make sure you include this time in your proposal)
  • how do you maintain and support a wide variety of custom mobile software applications
  • how do you keep your customer’s mobile software applications current with new versions of mobile operating systems and new handheld device technologies
  • how do you integrate your custom mobile software applications with a large variety of different backend databases and database applications
  • how do you do this all profitably

I have had many software and IT consultants contact me and say they have tried to develop a business targeting mobile software applications using Microsoft’s .NET development environment or other coding environments like Appforge, but it simply takes too long, and the cost is too high for the majority of their small to medium sized customers. They contacted me to ask if MobileDataforce has a solution that can address their business needs. The short answer is yes.

In order to profitably develop customized mobile software solutions for use on smartphones and handheld PDAs a large variety of business processes and/or industries, one must standardize as many of the design, development, deployment and support processes as possible. This goal is most easily accomplished by using a mobile software platform that provides these features in a configurable environment.

A mobile software platform enables your professional services organization to train on a standardized platform and to use a standardized methodology for rapidly developing and delivering custom solutions. With a common platform in use, the following benefits can be recognized:

  • Many of the requirements that mobile projects have are already pre-built in the mobile software platform
  • project estimates become increasingly accurate
  • software developers can easily support each other's projects and mobile applications
  • synchronization does not have to be developed, rather it is configured
  • mobile application screens don't have to be developed, rather they are configured
  • connectivity options don't have to be developed, rather they are configured
  • handheld device support is configured, rather than developed
  • mobile databases don't have to be developed, rather they are already included and only need configured
  • common templates and functions can be re-used on many different applications
  • technical support staff can easily de-bug and support new custom applications using visual de-buggers and management tools
  • design standards and functions make screen creation quick and efficient
  • application "clips" are reusable configurations and features that can be re-used on many different projects
  • the function library has over 220 pre-built functions that save design and development time
  • existing application templates can used and customized for multiple customer projects
  • new versions of mobile solutions can be published to the mobile user from the server
  • one set of code can work on Windows XP, Windows CE, Windows Mobile, Tablet PC and multiple screen sizes

The bottom-line - a large variety of mobile applications can be rapidly designed, developed, deployed and supported profitably if they are produced using a mobile software platform like the PointSync Mobility Platform. To program or code a large variety of different and customized mobile applications using .NET or Appforge is simply too expensive and takes too much development time for the average small to medium sized business. Speed and efficiency is required to serve this market. Mobile applications should be configured for these clients, rather than programmed.

Here are a few articles that address these issues in more detail:

Ultra-Rugged Portable Printers - O'Niel Printers for Handheld PDA Solutions

Have you ever thought what a challenge it would be to produce a ruggedized printer for use with a mobile handheld PDA? Think about the environment they are used in; rain, snow, dust, spilled coffee, climbing in-and-out of vehicles all day, dropping it on the bathroom floor when your belt is loose. I am sure the folks at O'Niel have a million stories they laugh about or cry about when customers are not around.

For those who feel "rugged" is not good enough for them, O'Niel Portable Printers offer the "Ultra-Rugged" line of microFlash printers.

These printers are also called "wearable" printers and they can be clipped to your belt. Hummm...what if you don't wear a belt? Where would you clip it? Perhaps you also need ruggedized clothing to support your ruggedized printer? These are popular with the route delivery folks who are leaving proof-of-delivery receipts with digital signatures. They can also be used for sales receipts, service requests and letters to your mother. That's an idea, a very short curled letter to mom.

Since these printers are "wearable" I wonder if you need to accessorize them? Do they come with matching handheld computers, styluses? Are there different colors, patterns and textures....I guess black goes with everything.

MobileDataforce develops customized mobile software solutions for companies, and these kinds of rugged, or ultra-rugged printers are often part of the solution. In this article I discuss a project we did for a company that manages parking garages and city parking meters.

In an earlier article I wrote about PrinTekMobile's FieldPro Printer.

Zebra also offers rugged and wearable printers.

AppForge sells assets; firm owes $1.8 million

Atlanta Business Chronicle - April 13, 2007
by Justin Rubner

Details have emerged about the fate of software-maker AppForge Inc.
The company, which unexpectedly shut its doors in mid-March, has sold its assets to Atlanta-based Hays Financial Consulting LLC, a firm that manages distressed, insolvent and bankrupt companies. AppForge, which developed software for PDAs and other mobile devices, filed an "assignment for the benefit of creditors," a quasi-bankruptcy that assigns all assets to the management company with the intent of paying off creditors as quickly as possible so shareholders can get something as well.

Gartner on Appforge

This blog article is from Nick Jones and Michael King at Gartner:

http://blog.gartner.com/blog/comminn.php?itemid=2147

Gartner's advice - "...develop a contingency plan for what you'll do if AppForge ceases to be viable, and be prepared to activate that plan some time in the next three months."

MobileDataforce is here to help with contingency plans.

Rent a Mobile Handheld PDA or Handheld Computer


Ryzex now offers rugged industrial handheld PDAs or computers for rent. How is this helpful? Many organizations need rugged handheld computers only for a specific 6 week period of time for year-end inventory, annual inspections, or a one time limited time project.
MobileDataforce sees a lot of these projects because our mobile software platform, the PointSync Mobility Platform, enables companies to quickly design, development and deploy these simple mobile applications.
Another important set of considerations is the ability to immediately synchronize and review the data that was collected on the mobile applications. In an earlier blog article I wrote about the challenges with using poorly trained, temporary workers for important data collection in the field.
