How much does it cost to develop a mobile App? 

I am often asked how much it costs to create a mobile app solution. So I decided to write about how I approach the question. 

What features are mandatory? 
I steer the conversation to what I term the “Minimal Viable Product”. That is, what features are mandatory for the product to be a success in the near term (i.e. within 6 months). Since time to market is critically important for an app, it is important to get the Minimal Viable Product in customers’ hands and gain feedback to evolve the product. Often the discussion gets really interesting. Some of the original items talked about are immediately dropped and others that were not initially considered rise to the forefront. A common problem is “feature creep”, which is important to control throughout every phase of the development effort. Often users want to employ features found in their favorite apps even if not needed in the app under discussion.Ultimately with enough patience we arrive at a set of features that frames the core of the product.  

How will users interact with the app? 
Building upon this collection of features we progress to user interaction with the app. I found making a simple sketch on a white board for each screen and type of use, is very helpful.    The results can easily be documented via digital picture.  I also use tablet drawing tools and prototyping software. Neither is as fast or as simple as the white board.  

Does the app need external data? 
Typical custom business apps require a “cloud” based server portal. Often a portal exists but we need to understand the portal API to send andreceive data. Usually not a big deal, but it is very important to scope this out ahead of time. You may find the portal’s API is not as rich and doesn’t provide the support that the app requires. Who is going to be responsible for the necessary customization?  Sometimes we need to create a new portal. Obviously this is a bigger deal and beyond the scope of this post ... more on this in a 
future blog. 

Which platform(s) to support? 
It used to be important to determine a specific platform to support, i.e. Android, iOS, Microsoft or Blackberry, assuming there is a dominant platform.  Modern apps must be targeted to a minimum of the Android and iOS platforms.  Right away a decision must be made regarding using Cross Development Platform tools or native app development tools ... more on this in a future blog. 

The answer is not long, but it requires intensive discussions up front. Now you can answer the question,  “How much does it cost to develop 

a mobile App?

My Favorite Productivity Apps

It's been 4 months since I abandoned my notebook as my primary computer. Now I use a PC Desktop computer exclusively at work and a tablet (iPad) when away. It has been a pretty smooth transition, experimenting with various apps that allow me access to all my data, documents and messages wherever I am.

I have narrowed down the app field to a few favorites:

Evernote is my go-to for keyboard-entered notes. It's easy to use, works seamlessly on all my devices and provides a simple way to create and manage text, audio and webcam notes. In Evernote, I am able to keep all of my notes and information organized by categories within notebooks. I have been using the free version for several years.

Notability is a more recent addition to my iPad. It is a low-cost app that is optimized for the iPad allowing me to completely replace a paper notebook. When typing notes is not an opton and more free-form entry is required this app is a terrific tool. Using a standard stylus, I am able to create and modify handwritten notes and diagrams easily, which can then be printed, or saved to a PDF file on a variety of cloud-based platforms including Dropbox. One of the best features of Notability is its sliding virtual wristguard preventing erroneous marks appearing on the document when resting your writing hand.

After experimenting with various cloud platforms for collaborating with team members and clients, I have chosen Dropbox as my primary storage and shareable resource. Although I have access to iCloud, Google Drive and SkyDrive, I found it is much too complex to try to use more than one. I chose Dropbox since I found it to be the most widely accepted and easiest to use. I am able to access and share documents, programs and images in Dropbox folders from my desktop PC, iPad and iPhone. One unanticipated bonus is that each time a document is updated the old version is saved. More than once it was helpful to go back and reread or restore from an earlier file version.

There are times when you just need to gain access to your work computer remotely. I have found that PocketCloud and its companion program that resides on the remote PC provides that capability in a simple-to-use application. This program basically converts your tablet to a remote desktop. It looks and feels like you are running Windows on your tablet and comes with a unique "mouse" pointer for navigating Windows remotely.

The biggest disappointment for me is the lack of good support for editing and creating Microsoft Office documents tools on the iPad. There are a variety of apps to read any Microsoft-formatted document (e.g. Word, Excel and PowerPoint). However the tools to create or edit MS Office files on the tablet are pretty simplistic, somewhat expensive and have limited access to cloud platforms for sharing. Even Microsoft's own Office Mobile for Office 365 (which requires an Office 365 subscription) only runs on the iPhone and only supports Microsoft Skydrive.

What are your favorite productivity apps?

Reflections On 3D Printing

Advanced Decisions recently co-sponsored a 3D printing and additive manufacturing panel discussion in Shelton, CT, which went great and opened my eyes to the astounding potential of 3D printing.

Here are some of the take-home points I gleaned from the presentation:

1. Not just about plastics. 3D printing can be used with all sorts of materials including metals, food and biological.
2. Biological 3D printing is on the rise, including capabilties for printing prosthetic body parts.
3. The focus isn't limited to creating mechanical parts but also new materials.
4. Found a niche in the market of replacing and repairing obsolete parts.
5. Ideal for rapid prototyping during new product development.
6. Manufacturing is undergoing transition from conventional to additive. Twenty years ago 3D printing could make 10s of units but can now make 100s and in some cases 1000s of units economically.

And if you're interested in learning more, here are some 3D printing articles I found useful:

When Is Software Ready to Demo?

During the development of custom software applications I am often confronted by the question of when to demonstrate software that is still under development.

The fear of every developer is to allow individuals to interact with the software before it is "ready." Of course, defining "ready" is the challenge--but so is defining who is giving the demo, its purpose and the composition of the audience.

In the early stage of development, as a developer or technical lead, I am the one pushing for a demo intended to uncover questionable areas of the requirements definition or technology issues as early in the development process as possible. (The actual software may very well be throwaway code.) For this to be effective, the test application should be created rapidly with a single focus (e.g. illustrate performance, screen layout, work-flow, or even error handling). The main idea is to eliminate as many unknowns as possible and to throw light upon aspects of a complex system as early as possible. We want to avoid going down a path too far, only to find we are proceeding in the wrong direction. These demos are typically oriented for technical people on the team as well as stakeholders.

The next opportunity for a demo is the more traditional usage. At this stage of development, the application is not complete but major functions are implemented and tested. The purpose is to measure the applications performance against requirements in a controlled setting. One example is to gain feedback observing typical users, where feasible, interacting with the application. Are there confusing areas? What happens when a mistake is made?

Another effective demo is to stress-test the application. This can be done by scripting data entry or transactions for example. Allow the application to run for an extended period of time and measure performance. Now I am looking to expose areas of weakness and potential bottlenecks that must be addressed.

Finally the software is code complete, tested and ready for release. It is safe to demo at a trade show and in front of potential customers. In fact, at this stage, the software is ready for beta site deployment.

The Changing Mobile OS Landscape

As we begin 2013, and to nobody's surprise, there are two dominant smart phone operating systems, Android and iOS.

Recent data in Business Insider states that as of Q3 2012 Android and iOS account for over 70% of the market share, with Android  accounting for about 75% of that share. In Q4 2012 alone BGR states that worldwide iOS and Android phones made up over 90% of the smartphone shipments.

But after digging a little deeper it becomes apparent that change is on the horizon for 2013.

Most of us are familiar with Windows 8 mobile handsets and Blackberry's recently announced Blackberry 10 handsets -- but lesser known are the 6 or so additional OSs that are in the works, including FirefoxOS, Jolla, Tizen and Ubuntu.

Though these oncoming options are good news for innovation and competition, I suspect our lives as mobile developers will be getting a bit more challenging.
