Mobile GIS App Planning Guide
October 30th, 2011 by Matt Sheehan
This article is targeted at individuals or companies looking to build a new mobile or Web application. It is a guide to help you move from a great idea to a great application. Oh, and it is short.
Let’s begin by imagining a house. Your dream house. The home you’ve always wanted to build. At the moment the layout, design, color etc. are in your head. New ideas are continually being added to this mental picture you are forming. You’d like to make this dream reality. But how? You look for professional help; maybe a builder, an architect.
Imagine you call this professional. You start the conversation as follows:
“Hello. My name is Joe. I want to build my dream house. It will need to have 4 bedrooms and a kitchen. How much will that cost to build?”
How do you imagine the builder, or architect will respond?
This is a silly example, which has little relation to software development, I hear you saying. Right? Wrong!
Software development is just like house building. You would be surprised how often we field calls similar to the above.
“We would like an application which does X. How much will that cost to build?”
If you are serious about making a dream reality. You need to start with something tangible. Mental pictures are only useful to you. Once you start involving others you need to transfer your thoughts.
Don’t get us wrong; cost at some point will be an important consideration. Cost will determine what is and isn’t possible. Cost may force changes to some of your ideas. Cost will determine who you choose to do the work. But starting with cost without providing a well thought out, and clearly laid out picture of your thoughts. Will leave your dream just that, a dream!
Mobile Application Development Brainstorming
Let’s start with brainstorming. This is the process of transferring ideas to paper; often many crumpled pieces of paper. Sure there are tools out there to create mind maps. We are old fashioned. Put everybody in a room, grab some paper or a white board and start scribbling. It’s amazing what you can come up with. Figure 1 below are the initial roughs for a mobile app we recently worked on. It shows roughs for an IPad and IPhone version of the same app.
Figure 1: Mobile Application Roughs
These scribbles can be as detailed as you would like. But they are a huge step forward. You’ve transferred thoughts to something tangible. A format others can understand.
Mobile Application Flow
Ok, so we have our initial picture(s) of what the application will be. Let’s formalize things a little. Provide an idea of application flow. Figure 1 includes some simple flow; if I click button X it takes the user to screen 2 which shows content A. Get it?
Mobile Application Development Professionals
So now is it time to turn to a professional? Definitely maybe. If you are comfortable that you have all the application pieces in place, in a format which is understandable to a stranger. Definitely. Remember, pictures work better than words. Always. The words simply support the pictures.
Planning and design are two crucial parts of the application development process. But these are only relevant once you have decided on who will help architect and build the application.
You will find that the professionals you choose to show your application roughs will have questions. Good roughs will help others understand what you are trying to do.
Mobile Application Development Estimates
With a good understanding of what you are trying to build. A software development company can start thinking about some of the technical challenges. This then leads to time estimates for developing the application. Ultimately to the magic number. Estimated cost.
Here is a dirty secret. Developers often take their initial time estimate based on the roughs we have described above. Double it. Then add 10%. What ….because they are greedy?
Estimation is a very inexact science. A developer will always try to overestimate rather than underestimate. Think about it. What would you prefer, a developer saying:
“Great news. We finished the work for less than you expected to pay.”
“The work will take longer than expected. That will cost you more money.”
Mobile Application Development – Making Changes
So you find the perfect company to do the work, at the right price. You start moving forward. Then change what you want. Maybe you forgot something, or, have new ideas. Does that change the cost? Quite possibly. By how much? Ask the question. It is surprising how often people make changes to applications, without considering cost implications.
Mobile Application Development & Successful Outcomes
The best applications in the mobile and Web markets are those which start with a great idea. An idea which is transferred to an understandable format and shared. Discussed. Changed. A great development company found to do the work. At the right price. Planning, design, feedback, changes occur iteratively. Your dream becomes reality.
