One of the industries that has competed quite well and grown in statue in the GFC (Global Financial Crisis) is the Enterprise Mobility Market. Companies have invested in mobility technology such as PDA's and while their work force may of been decreasing they have been increasing the mobility of each worker by putting a PDA in their hands.
Of course with the right software and the right PDA it can be a powerful tool to have. The user does not need to go back to the PC for any information as they can simply use the PDA for price enquiries in retail, or receive and pick goods in the warehouse, or use the PDA to record mobile sales. There are a number of applications the mobile PDA can be used for and this is what is called Enterprise Mobility Solutions.
With the increase of companies investing in Enterprise Mobility Solutions I have seen an increase of software development companies offering PDA solutions. One of the main reasons this can happen is because of the very low barrier to entry in the software development industry. What the consumer needs to take careful note about is it is quite cheap to do a 'Release 1.0.0' of a product but where software development companies spend their money is the continual maintenance of the product which leads to the next releases.
The software product will constantly receive modifications for updates and therefore will need increased testing. The environment will change whether its Windows updating to a new operating system or whether it is the accounting package your are integrating with receives updating.
About 10 years ago we saw the increase in software companies putting their hands up in website development but slowly they removed themselves from that space. Enterprise Mobility and Website Development are niche, and require specialists. My opinion is just like the website developers soon will we see the decrease in software companies offering Enterpise Mobility solutions.
