Chapter 1 TCO assignment
total cost of Ownership (TCO)
Seattle Fire Department Use of Data911 Mobile Computers
Hard cost:
Hardware: PC, laptop and peripherals
Program: upfront fees, license fees, and the costs of development
Development system: application design, development and integration and staging
Soft costs
Training: Initial user training
Operational maintenance system, and technical support 3rd party, and internal technical support, upgrades, and application management
Stop: lost work / wages, lost revenue, and hardware replacement
The ruggedized devices used by most of the organizations in the study VDC to address the challenges of the mobile environment: extreme changes in temperature and dust / particulate matter, vibration and physical blows, and the contamination of Biochemistry, and humidity, and water / rain.
The two important conclusions from the study:
Was ruggedized mobile devices at a lower cost of ownership of 53 % of the non- ruggedized devices? Take into account the costs of the purchase price, and the guarantee fee / maintenance, and replacement parts and lost work / wages, and the cost of technical support, etc. Note: represent the productivity lost nearly 52% of the total cost of ownership of the devices ‘.
The Business plan on Latest Developments In Input Output And Storage Devices
Latest Developments in input, output, and storage devices Intel continues to revolutionize the way the world experiences technology. Intel announced the demonstration of the worlds first electrically driven Hybrid Silicon Laser. The hybrid silicon laser is a key enabler for silicon photonics, and will be integrated into silicon photonic chips that could enable the creation of optical data pipes ...
Was ruggedized mobile devices failure rate, which was 63% less than the hardware is comparable ruggedized: 6.5 % failure rate for ruggedized versus 17.5 % for non- ruggedized? The main source of the failure of the hard drives, displays, keyboards.
C. Seattle fire experience
Took over the distribution of costs in the research study VDC replacement cycle 4.5 on laptop ruggedized year and 3 years for laptop is rugged. Experience in the Seattle Fire Department with computers Data911 is that the replacement cycle is really 8 years for the entire PC MDC is rugged and only last about two years if installed in a car fire.
Assess the total cost of ownership, below, on the basis of 21 months of maintenance work orders, and purchases and upgrades laptop Data911 over a period of ten years. Is performed many of the assumptions in the assessment?
Lost wages is not really a factor in this assessment. When it fails the laptop to the company and fire dispatchers use the 9-1-1 dispatch center and radio messages broadcast the situation until the problem is corrected them DC. Devices did not take the fire out of service for non- laptop, not the firefighters down time or have been incurred over time.
The software costs are not included because the cost is basically the same for computers, rugged and non- rugged.
Require rugged devices is 2-fold IT technical support as a result of the failure of components increased. This factor is based on the standards set out in the study VDC – in. E., The rate of hardware failures is double the number of devices rugged terrain.
1. Labor costs / SUPPORT
Table 1 is based on an assessment of the Office 334 service calls associated with the MDCS and peripheral devices in cars Seattle Fire Department. Therefore, 149 were specific to the laptop. Calls the annual problem is expected that a number of the problems listed in Table 1 (based on the sample period, 21 months)
Table 1 – Support Cost
Problem Type|Avgas Labor Hours|Annualized # of Problems|Total Hours|
Hardware|2|43|86|
Software|1.5|14|21|
Investigated but no problem|1|28|28|
The Essay on University Costs Dollars Cost Year
University Costs How have university costs changed over the years? University costs have been steadily increasing throughout the last ten years as more and more students apply. However, foreign students feel the brunt of the hikes as they pay around the area of three times as much as in country students. What are some of the costs when going away to university? Costs that you are expected to cover ...
Total||85 problems|135 hours|
The Social Fund for Development has 100 computer Data911 vehicles in service in the fire. With the burden of the entire business rate of $ 120 for technical support in the annual cost of the MDC are:
($ 120 labor cost problems × 135) / 100 = $ 243 computers in the Movement for Democratic Change in year
The Ministry does not have the support costs detailed notebooks and rugged is installed in the vehicle.
So, for this exercise has been applied a factor of 2 to support the costs of the MDC on the basis of a study VDC – in. E., And doubled the cost of supporting the MDC to represent the cost of supporting a laptop is rugged.
2. COST devices
Table 2 shows the cost of Data911 MDC and the cost of a laptop is a rugged over a period of 8 years.
MDC includes the initial cost of 1 year 3 year warranty on all parts. Then there is the cost of $ 276/year extended warranty. Also, in Year 5 there is a cost to upgrade the CPU (along with a new video cable).
Not required to upgrade the CPU, but on the basis of the experience of the Social Fund for Development in the life of Data911 MDC can be extended dramatically buy only raise the level of CPU versus buying a whole new device. Cost of the device is supposed to ensure rugged for 3 years, but our experience with laptops permanently installed in vehicles in the field is that the useful life of the operation is about 2 years. This means buying a laptop replacement every 24 to 30 months.

2 the cost of Data911 M6 second with 4GB RAM, 80GB HD, a rugged keyboard with a backlit, touch screen display and video cables, and Mountain View and 3 years warranty comprehensive.
The Essay on Portable media device
Who does not have at least one portable media device? Virtually everyone from the middle class has one. We see them all the time; people with the trademark white earphones walking our streets, people in cafe’s surfing the web with their laptops, executives setting an appointment with their blackberries, children bowed down, playing their DS’s or PSP’s, and cars that have more screens than the ...
3. Total Cost of Ownership
As shown in Table (3) and total cost of ownership of Data911 MDC is actually less than the laptop is rugged.
Table 3 – Annual Cost
|Laptop|MDC|
IT Labor|$487|$243|
Hardware|$1,183|$1,364|
|$1,669|$1,607|
And, of course, other agencies will have different experiences and results when assessing the useful life of the real devices and measuring the level of effort to support each device. The wear -and-tear on the devices be different and will vary fixed costs / other soft -agency. Issues to consider are:
MDCS will be installed permanently in a vehicle fire (in docking stations or fixed mount)? Will the devices in cars all the time experience much more than the damage the devices that are manually?
How will you address the pollution? In the fire service – especially for those who provide EMS – computers in the field need to take the process of decontamination. It is highly unlikely that the non- rugged or even semi-rugged devices can survive very long if keyboards and touch screens and other exposed areas need to be cleared on a regular basis.
What is the strategy that will be used for locking devices? Tampering and theft and issues that need to be addressed when considering fixed- mount devices (such as Data911) or removable devices such as laptops and tablet devices.
What is the remote management software is used to support the MDCS? There are many products on the market that can reduce support costs both ruggedized computers is rugged and dissemination of information technology.
If any agency would like more information about the experience of the Fire Department in Seattle with Data911 and management of laptop computers in a fire Leonard Roberts, please contact, the Seattle Fire Department Director of Information Technology
