Five Components of Mobile Change and Opportunity

C E 5.2 Why are mobile systems important?

Figure C E 5.2 Five Components of Mobile Change and Opportunity

Blank	Hardware	Software	Data	Procedures	People
Impact of mobile systems growth	Many, many more mobile devices will be sold.	Compact interfaces; new technology for active users; application scaling.	More data, but more information? Less device real estate means fewer ads possible.	Always on, always at work. Employee lifestyle becomes hybrid of personal and professional.	Ability to thrive in a dynamic environment more important.
Industry changes	P C s less important; high demand (and requirement) for innovative devices as well as cheap copycats.	H T M L 5, C S S 3, and JavaScript increase capability of thin-clients.	Loss of control. Ad model in danger?	Personal mobile devices at work.	More part-time employees and independent contractors.
Career opportunities	Jobs for mobile device sales, marketing, support.	New technology levels the playing field for H T M L 5. Business expertise needed for mobile requirements. New companies!	Reporting and data mining even more important. Design of effective mobile reports.	Innovative use of just-in-time data. Need for adjusting business processes gives another premium to nonroutine problem solvers.	Independent contractors (and some employees) work where and when they want. What is this new social organism?

Native vs Web Applications (2 of 2)

Blank	Native Applications	Web Applications
Development languages	Blank	H T M L 5 C S S 3 JavaScript (scripting language
Developed by	Professional programmers, only	Professional programmers and technically-oriented Web developers and business professionals
Skill level required	High	Low to high
Difficulty	High	Easy to hard, depending on application requirements
Developer’s degree	Computer science	Computer science Information systems Graphics design
User experience	Can be superb, depending on programming quality	Simple to sophisticated, depending on program quality
Possible applications	Whatever you can pay for…	Some limits prohibit very sophisticated applications
Dependency	iI O S, Android, Windows	Browser differences, only
Cost	High. Difficult work by highly paid employees, multiple versions required.	Low to high ... easier work by lesser-paid employees, only multiple browser files necessary. Sophisticated applications may require high skill and pay.
Application distribution	Via application stores (e.g., Apple Store)	Via Websites
Example	Vanguard iPad application (free in Apple's iTunes store)	Seafood Website: www.wildrhodyseafood.com Picozu editor: www.picozu.com/editor

Developing Native Applications (1 of 2)

C E 5.3 How do native and Web-based mobile applications compare?

Run on any operating system and device.
Serious, heavy-duty, professional programming languages.

Objective-C,

C++, Swift, Java, V B. NET, etc.

Close control over computing device, enable creation of sophisticated and complex user interfaces.
Fast and efficient use of memory.

Limited to type of operating system.
Costly development.

Developing Native Applications (2 of 2)

C E 5.3 How do native and Web-based mobile applications compare?

Web development languages: HTML5, CSS3, JavaScript.
Browsers handle idiosyncrasies of operating system and underlying hardware.

HTML5: support for graphics, animation, 2D animations, other sophisticated user experiences.
CSS3: used with HTML5 to specify appearance of HTML coded content.
JavaScript: provides underlying logic of application.

Which is Better?

C E 5.3 How do native and Web-based mobile applications compare?

Depends on:

Strategy and goals.
Application requirements.
Budget.
Schedule.
Tolerance for managing technical projects.
Need for application revenue.

Thin-client applications cheaper to develop and maintain.
May lack “Wow!” factor

Survey of Organizational B Y O D Policy

C E 5.5 What are the challenges of personal mobile devices at work?

Figure C E 5.11 Six Common B Y O D Policies

A BYOD policy is a statement concerning employees’ permissions and responsibilities when they use their own device for organizational business.

Long Description:

Five columns represent control; low towards the left and high towards the right. 3 rows represent functionality; high towards the top and low towards the bottom. The details are as follows:

Full VPN access to organizational systems: blank; blank; You’re responsible for damage; we’ll check it out, reload software and data, and manage it remotely; if you connect it, we own it.

Organizational services on public internet: blank; we’ll offer limited systems you can access from any device; blank; blank; blank.

Access to internet: we’ll be a coffee shop; blank; blank; blank; blank.

C E 5.5 What are the challenges of personal mobile devices at work?

Figure C E 5.12 Advantages of Example B Y O D Policies

BYOD Policy	Description
They don’t exist	Organization looks the other way when employees bring mobile devices to work.	None
We’ll be a coffee shop	You’ll be able to sign in to our wireless network using your mobile device.	Packet sniffing of employee mobile device use at work.
We’ll offer limited systems you can access from any device	Organization creates https applications with sign-in and offers access to noncritical business systems.	Employees gain public access from any device, not just mobile devices, without having to use V P N accounts.
You’re responsible for damage	Threatening posture to discourage employee use of mobile devices at work.	Appear to be permissive without actually being so.
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 I S department.	Employee buys the hardware (perhaps with an employer's contribution).
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.	Ultimate in control for highly secure work situations (intelligence, military).
