Week Four:
Chapter Three Extension: Mobile Systems
3.1 What are mobile systems?
Mobile Systems:
information systems that support users in motion
access the system from any place using any smart device
Major elements in a mobile system
users in motion
mobile device:
small, lightweight, power conserving computing device that is capable of wireless connectivity
cloud base resources
3.2 Why are mobile systems important?
mainly because of the size of the market
mobile use is favoured by the young - young cohorts will further increase mobile systems use in the future
HARDWARE
Impact of mobile systems growth:
many more mobile devices will be sold
Industry changes:
PC's less important; high demand for innovative devices and cheap copycats
Career opportunities:
job for mobile device sales, marketing, support
SOFTWARE
Impact of mobile systems growth:
compact interface; new technology for active users; application scaling
Industry changes:
html, css3, and JS increase capability of web apps
Career opportunities:
new technology levels the playing field for html, graphics skills
DATA
Impact of mobile systems growth:
more data, but more information extrapolated from data
Industry changes:
loss of control, less room for advertisement (smaller screens)
Career opportunities:
reporting, data mining even more important
PROCEDURES
Impact of mobile systems growth:
employee lifestyle becomes hybrid of personal and professional
Industry changes:
personal mobile devices at work policy
Career opportunities:
Innovative use for just-in-time data. Need for adjusting business processes gives another premium to non-routine problem solvers
PEOPLE
-
Impact of mobile systems growth:
ability to thrive in a dynamic environment is more important
Industry changes:
more part-time employees and independent contractors
Career opportunities:
independent contractors (and some employees) work where and when they want
3.3 How do native and web based mobile applications compare?
NATIVE APPLICATIONS
Development Languages:
Objective C, Java, C++, Swift (
object-oriented languages
) - gives close control over computing device, enables creation of sophisticated and complex UI
Developed by:
professional programmers only
Skill / Difficulty:
high
Cost:
high, difficult work by highly paid employees
Limited by type of operating system (thick-client)
Example:
an app only in the apple iTunes store
Which one is better?
choice depends on strategy, goals, requirement for application, budget, schedule, tolerance for managing technical projects, need for application revenue
generally,
web native application are cheaper to develop and maintain, but lack wow factor
WEB APPLICATIONS
Development Languages:
HTML, CSS JS (
scripting language
)
Developed by:
professional programmers, technically oriented web developers and business professionals
**Skill / Difficulty: low to high, dependant on application requirements
Cost:
low to high - easier work by lesser paid, sophisticated applications may require high skill and pay
can be used on any browser (thin-client)
Example:
www.website.com.au
3.4 What characterises quality mobile user experiences?
User Interface:
presentation format of an application
User Experience:
the way the application affects the user's emotions and motivation to continue to use the interface
Characteristics of Quality Mobile User Experience:
feature content and support direct interaction:
quality mobile interface should place the primary emphasis on user's content
chrome:
refers to the visual overhead in a computer display - menus and there apparatus that drive application
direct interaction:
using content to drive application behaviour
use context-sensitive chrome:
pop-up in the display when appropriate
provide animation and lively behaviour:
capture attention with motion and sound
design to scale and share:
apps designed to be able to scale up and down without appearing awkward or taking over device & to share data
use the cloud:
websites, text, email and other services
extend application onto servers
use more powerful servers
support roaming across devices (transparently)
data and news
push data:
data that the server sends or pushes onto the device
pull data:
data that the device requests from the server
3.5 What are the challenges of personal mobile devices at work?
EMPLOYEE USE OF MOBILE SYSTEMS AT WORK
Advantages
cost savings
greater employee satisfaction
reduced need for training
higher productivity
reduced support costs
Disadvantages
data loss or damage
loss of control
compatibility problems
risk of infection
greater support costs
Bring your own device (BYOD) policy:
statement concerning employee's permissions and responsibilities when they use their own device for organisational business
SIX COMMON BYOD POLICIES
1. They don't exist
- organisation looks the other way when employees bring mobile devices to work
2. We'll be a coffee shop
- you'll be able to sign in to our wireless network using your mobile device
advantage:
packet sniffing of employee mobile device use at work
3. We'll other limited systems you can access from any device
- organisations creates https:// applications with sign-in and offers access to non critical business systems
advantage:
employees gain public access from any device, not just mobile devices, without having to use VPN accounts
4. You're responsible for damage
- threatening posture to discourage employee use of mobile devices at work
advantage:
appear to be permissive without actually being so
**5. We'll check it out, reload software, then manage remotely - employees can use their mobile devices just as if they were computers provided by the corporate IS department
advantage:
employee buys the hardware
6.if you connect it we own it
- employees are not to use mobile devices at work. if they do, they lose them. Part of employment agreement
advantage:
ultimate control for highly secure work situations
