ITIL 4.7.10 Tablets and Smart Phones 4.7.10. Tablets and Smart Phones: It has been agreed that the application will be used by authorized people with tablets and smart phones. In 2011, USD500 tablet technology has a limited graphic resolution of 1024 pixels width. This is in contrast with commodoty USD300 15-inch laptops with a 1330 pixel resolution and $300 desktops with 20-inch TFT screens running 1600 pixel resolution. While all productivity research shows that people with larger screens and more screens are more effective that people getting by on a small screen; support for small screens has been built into the design. Web Page Size and Position: When dealing with large screens, productivity is maximised by careful positioning and sizing of each page. When dealing with small tablets, page positioning and sizing has little significance - productivity is simply lower. Sheet is the specification name used to identify where more than one page is appended to the top page in an automated way - many pages to one sheet. Normal is the specification name used to identify where each page will replace or overlay the prior page. History is the specification name used to identify where a history page is opened part way down the change page so one page can be compared with the other. The application has been assigned a default page width of 1024 pixels - optimised for small screens with low levels of productivity. Screen Layout: Please with a little tablet will be obliged to scroll down the page to view the large amount of data that is needed to define a risk. Please working in the office with a large screen will be more productive because they will be able to view most information as a single window. Please with a little tablet need large finger sized icons to navigate, while people in the office may use mouse sized icons for more economy of space. Both large screens and small screens are supported at the same time, it is a user choice of what page to select. As tablets increase in resolution to support the current 1280 resolution, then the investment in small resolution screens can be discarded. Choice: Choice is an application development program that can never be cost justified and can only happen as part of a continuing improvement policy. To spend some months building alternative layouts at the begining of the project is certain to cause the project to stall, run out of investors and end up suiting nobody. The committee that get to choose the colour scheme is the people who put the lights out after the company closes down. Icons: The current icon library has evolved over many years to match the objective of increasing the productivity of people by delivering more effective pages of information. This technology uses both 32 and 16 pixel icons that are optimised for people with a mouse, rather than a fat finger. Tablet touch screen technology demands that all 16 pixel icons are upgraded to 32 pixels with a reduction in navigation abilities from each dashboard - touch is not as precise as a mouse. The law states that people with visual disabilities need to be able to switch to a larger font size with a consequence of less data shown on a pages - this must not significantly distract from how the application is used. It will take time for the left hand menu to correctly evolve to support 32 pixel icons - a double menu bar has proven to be more effective. User preferences: No one method of working could be correct for everybody with all kinds of visual capabilities and computing devices. The 64 pixel header is optional can could be swithed to a second menu bar to improve productivty when using touch screen technology. The right margin exists for gadgets to improve productivity, but could be selected as needed using a menu. The left hand menu could switch to the top or bottom of the page - each user will have their own idea of what it should be. Browser Tabs: The debate over pages and tabs is subjective and largely influenced by each users computing device.   A few facts can help to point users to become more effective and productive. 1. When an extra tab is opened, the same computer thread is used to process that thread and any problems with that thread will compromise the tabbed window - the application session could be lost. 2. When an extra window is opened, a new computer thread is used to process that window so if the thread fails for any reason, other opened windows are not terminated. Policy: A dashboard is always open and is automatically refreshed periodically to ensure the secure session with the server is maintained.   Other application procedures use a different window with a different thread that if it fails just that window closes amd does not compromise the secure dashboard window. Task Bar: All computers have a task bar that shows open windows - click on any task bar icon to view that window.   Some browsers have tabs and others do not, but all computing devices have a task bar - including tablets and smart phones. Position: A benefit of opening a new window is that the window position and size is under application control - tabbed pages cannot be positioned or sized.   For the application architect this means that new windows can be stacked by design to maximise productivity. A benefit from running professional applications for the last decade is that we have evolved to eliminate client problems with the very best technology that the IT industry can deliver.   We are paid to deliver a non-stop application service to many thousands of people every day and that includes delivering application facilities that can cope with overloaded computers, inadequate memory, smart phones and executive toys.   The common factor is that some of the finest minds in the world have established codes of practice that simply work.
