ARCHIVE FOR THE ‘ian-davies’ CATEGORY

Motion Computing's Ian Davies returns to the question of what defines field service...

We have previously discussed the emerging differences between enterprise mobility and field service.  The underlying current of that discussion was which fish would eat the other.

In the cold light of day, it is clear that (from a market and technology perspective at least) field service management will live ‘within’ enterprise mobility.  But this overlooks a critical point of distinction - what does a field service definition of enterprise mobility look like?  What are the actual, tangible hallmarks of an FS deployment and what does this mean for selecting the right technology?

 

Firstly, don’t even look at the technology.  Look in the mirror.  If you are wearing a hard hat, chances are you are field service and much of the discussion around enterprise mobility may not apply to a great extent.

 

Of course, the same reason you are wearing such a fetching headpiece - safety - does need to be reflected in the choice of mobile technology.    This may mean the right IP ratings for ruggedness, the right protection of critical information or the right certifications for specific environments such as explosive atmospheres.

There are other clear hallmarks of a field service deployment, driven by the needs of the mobile worker.  Whilst these can be broadly grouped into connectivity, computing power and security, it is worth bearing in mind what each of these labels mean to the different vertical markets within field service.

Connectivity

Productivity in the field depends on being connected to other people and resources - be they colleagues at head office, other mobile technicians and engineers or databases thousands of miles away.  When a signal connection drops for a consumer on the high street it is an annoyance.  When a signal drops for an engineer on an oil rig, it can paralyse the operation of the whole drilling platform.

Elsewhere, many public safety and utility businesses operate within dense metropolitan areas where network saturation can impact wireless performance - especially 4G.

Not all enterprise-focused mobile devices are compatible with the latest 4G wireless technology, which means signal availability and data speeds can be unpredictable.

One of the arguments recently put forward has been to view the level of ruggedisation that a tablet needs not as a consequence of the environment in which it operates, but as a result of how critical the process enabled by the technology is, to the business.  The same goes for connectivity - if the connection to the back office or elsewhere is paramount to enabling a given task, it must be backed up with redundancy and alternative options.

Computing power

Software applications for use in the field grow ever more sophisticated, incorporating more and more data and handling increasingly complex processes.  At the same time the need for power efficiency (and the subsequent impact on battery life) remains top of the list of concerns for most deployments.

 

For example, the latest 5^th Gen Intel^® Core™ processors (Broadwell) including the i7 vPro™ chipset, provide the power to quickly move through computation-intensive applications, while increasing overall power efficiency. However, again applying the idea that the process, not the environment is the defining aspect of selection, it is important that such technology is paired with the ability to hot-swap the battery in the field.

 

Despite the fact field service is - by definition - away from the traditional desk environment, data processing needs remain the same. Devices must offer the same processing capabilities on devices such as tablets as they do on a desktop or laptop.

Security

From a security perspective, the net result of a more connected mobile workforce with access to increasingly sensitive information is greater vulnerability.  Stories of lost laptops still make the headlines and more endpoint devices offer more openings to malicious attacks on a corporate network.  Part of the answer here lies in greater training and better procedures for field service personnel.

 

 However, technology can also help - multi-factor authentication capabilities through a combination of password, fingerprint scanner and smart card readers for environments such as healthcare, public safety and manufacturing - are important considerations.  Likewise encryption is a vital component of an increased security profile, with remote management capabilities and kill switches necessary in some cases.

 

Of course, these three areas are neither exhaustive, nor the exclusive preserve of field service.  But they do give serious points for consideration to those procuring technology such as notebooks or tablet PCs for use out in the field.

The needs of the specific industry must also be taken into account (an aspect as equally applicable to hardware as software) if the field service personnel equipped with this technology are to achieve the productivity savings that drive so many field service and enterprise mobility deployments alike.

Key to these savings are the peripherals that will augment a tablet PC and enable it to fit into the workflows of field service personnel.  Vehicle mounts are a great example, as well as carry cases and charging docks.

These are not just additions that are “nice to have” - they form the bedrock of the tablet fitting in to the jobs being undertaken in the field and improving productivity.  They are also, like hard hats, a great indication that the field service teams have the right kit to get the job done.

Motion Computing's Ian Davies looks at the true value of rugged computing and why going for the cheaper option is a false economy...

Every IT director and line of business manager looking at a tablet PC deployment will, at some point face the question “why invest in a ruggedised solution when we can get two or three consumer units for the price of one ruggedised tablet and just swap them out if they go down?”  Even allowing for the restrictions of consumer devices in terms of software, operating systems and processing power, the initial numbers can - at first - be attractive.

But, speak to any manager or director who has then faced the issues of deploying and managing non ruggedised hardware and those numbers soon evaporate.  In fact, research shows that the total cost of ownership for non-ruggedised tablets is three times greater than ruggedised alternatives over a three year period.

A recent survey from VDC highlights the causes of this expense in using consumer grade units.  As part of a research project among IT decision makers at 215 companies managing a mobile device deployment, VDC discovered that the leading cause of device failure was that the tablet had been dropped.  The second cause was software issues but this was only marginally ahead of exposure to water and liquid (and just over 1 in 4 tablet PCs will face such exposure). Other leading causes of failure include excessive heat / cold, dust exposure and vibration.

Summarising these factors, when respondents were asked to rank their satisfaction with various tablet features, the level of hardware ruggedisation around dust and water was ranked lowest.  By comparison, satisfaction around issues such as operating system was far greater.  Simply put, we now have the level of tablet deployment that means customers are facing the issues of fragile, non-ruggedised tablets as they fail in the field and that those issues have become the dominant concern, especially for those applications involving wet environments.

  do such factors around device failure matter?  Because each device failure can cost an organisation upwards of 200 minutes in lost labour - a little under three and half hours.  This can be seen in a loss of productivity, the time spent to redeploy a new unit and the time spent in between with diagnosis and any necessary repair. And it is worth noting that these costs are per device failure - in a fleet of hundreds of units, this can soon amount to weeks of downtime.

 

Even without incidences of failure, it is worth noting that these softer costs make up a substantial amount of the TCO of a unit.  Initial and ongoing user training, system maintenance, technical support, upgrades and application management all contribute to TCO and for a consumer unit, these can be substantially more than a dedicated enterprise tablet.

However, factoring in the incidences of failure, the research found that IT costs and loss of productivity accounts for 89% of the TCO of consumer grade tablet PCs. To put that into hard figures, on an annual basis, a ruggedised tablet will have a TCO of around €2000.  By comparison a non-ruggedised tablet costs in excess of €4000.  That is despite the fact that the initial hardware cost of a ruggedised tablet will likely be double that of a consumer unit.

Figures such as these show the increasing importance for strong metrics such as ROI and TCO to not only validate investments but to track and measure use of mobile solutions within the enterprise throughout deployment. Furthermore it is clear that, because line of business mobile solutions are often mission critical, organisations need robust and reliable solutions to support them.

It is critical to align the right mobile solution with the users and application environment. But amidst the flood of consumer technologies in the enterprise that has driven a spike in failure rates, it is important to remember that consumerisation of IT all about introducing consumer experiences – NOT technology – into the enterprise.

Recognising this, many businesses now see that the cost of supporting and managing a device post deployment is just as - if not more - important that the upfront device investment.   There is much more to consider than the initial set up costs of the mobile solution. Organisations demand that IT investments deliver tangible benefits and incur predictable costs.  From platform consistency and sustainability, to the impact of device failure in various use scenarios – it is critical to understand the actual cost and impact of your mobile device deployment against the choices available and the increased interest in low cost consumer grade tablets.

Against a pan-European backdrop of regulatory change, increased consumer awareness of price and choice and concerns over energy security, the utility sector is facing many challenges and opportunities over the next decade.  Motion Computing's Ian Davies discusses... 

Within the industry itself, the concerns of customer service improvements, the aging workforce and enabling a more responsive field workforce are driving many utilities to re-evaluate key business operations, processes and the technology that supports them.

Core to many of these initiatives and achieving new levels of service and field worker productivity is ensuring seamless access to critical asset and customer data. Research has confirmed a strong correlation between a highly productive mobile workforce and ensuring utility networks deliver continuous service and meet customer service standards.  As a result, empowering a mobile workforce is now a key concern for many utilities.  As both the workforce and utility infrastructures age, many utilities are considering wireless technologies to help manage information, assets and workers.

Mobile workforce applications in utilities:

Connecting your mobile workforce with the information and human resources they require delivers many strategic benefits to utilities.  These can be grouped into three main areas - reduced operating costs, improved asset life and increased customer satisfaction.

At the tactical level these benefits are seen in metrics such as increased on-time responses, greater “wrench time”, and more job completions. Travel to the next job is less which not only saves time, but also reduces vehicle emissions, and cuts down missed appointments.

The financial savings of this increased productivity are seen in decreased crew hours and overheads. Further improvements to the bottom line can be realised by automating the work order process to help reduce operating costs.

Additional benefits include enabling seamless, real time and interoperable communications with field workers, centralised support staff, utility management and first responders in emergency situations.  Management is improved by incorporating training, work administration, and performance monitoring.  And by improving collaboration and enhancing knowledge transfer, utilities can begin to address the challenge of an aging workforce.

The applications to enable these benefits can be covered off in three main categories:

Next Generation Asset Management and Analytics

Advanced analytics draw on powerful analysis platforms to present data and complex interrelationships in a manner designed for the business and operational needs of different types of utility employees. From the field, to the asset manager, to the board room, asset analytics provide critical intelligence to ensure that appropriate decisions can be made in real time.

Modern mobile versions of asset analytics provide utility field crews with a thorough understanding of an asset’s inspection and maintenance history and help field crews better understand the importance of the accuracy of data they are capturing.

Real-Time Scheduling

Customer service in the utility sector has been lagging and much of this has to do with how customers engage with their local utilities.

While many experienced field technicians generally know their territory and the likely duration of different tasks, the same does not hold for less experienced workers and frequently, schedules developed by less experienced workers, can result in productivity decreases. Mobile workforce applications that include real-time scheduling prevent this productivity drop-off. As the crew finishes its emergency tasks, real-time schedulers immediately produce new schedules that start from the current location and follow rules for task priority and drive time.

Job Training and Monitoring

Experienced workers carry in their heads the correct safety techniques and job structure. Mobile workforce software incorporates that knowledge and makes it accessible via tools like checklists and context sensitive help. It ensures that less experienced crews meet utilities' safety and compliance guidelines.

As a result, mobile workforce management software can standardise tasks and guide newer employees through each step, decreasing the time it takes to become productive.

These applications also enable better and more accessible asset records, improved documentation, and integration with video and image management solutions to provide remote support capabilities.  Integration standards also enable efficient cross-departmental business processes.

The right platform

A variety of mobile form factors are being used to support field workers in the utility sector, and tablets represent an increasingly viable choice.  The tablet provides a strong balance of a highly portable device with sufficient display real estate to support the graphics rich applications common in the utility sector.

As a result of these benefits, according to research by VDC, over six in ten utilities are either currently using tablet PCs or are evaluating tablets for use among their field workers.

While much of the attention directed towards tablets has been for consumer-oriented devices, consumer devices have limitations when it comes to enterprise-use cases.  The challenges end users express with consumer tablets in the enterprise span everything from core device functionality to management of these devices by enterprise IT departments and their security limitations. The ability to seamlessly interact with backend systems and integrate with legacy applications including support for capabilities such as rapid updating also rank highly in this list of concerns.

For utility service technicians, critical requirements of a successful mobile platform include:

• Durable, yet lightweight design. Failure rates are a critical concern as they can substantially disrupt workflows. Devices designed to withstand inclement conditions and the potential for occasional drops are ideal. Another key requirement is the ability to interface with the display with wet hands or in wet conditions.
• Display daylight visibility. While consumer device displays are visually appealing, in sunlight or ambient light conditions they wash out. A display that can be easily read in these conditions is a key benefit, if not essential
• Application suitability. Many back-end utility applications are designed to operate in a Windows environment. Leveraging these platform investments and ensuring forward compatibility is critical for many utilities.
• Input/output configuration options. Mobile workforce management applications require a variety of input/output configuration options ranging from signature capture, bar code, GPS, image and video capture, multi-touch interface and magnetic stripe readers.
• Embedded wireless functionality. With more data moving to the cloud, a seamless wireless network connection, carrier (3G/4G) or Wi-Fi is critical.
• Unobtrusive, yet robust security.   Security requirements are becoming even more stringent due to increased regulation.  For mobile devices this likely means both hardware-based encryption, trusted boot functions, data-at-rest encryption, and remote lock and wipe capabilities. While security – especially for mobile insurance solutions – needs to be unobtrusive, sacrifices for the sake of ease of use cannot be made. [/unordered_list]

Based on these demands, and the driving force of customer service improvements, an aging workforce and a need to reduce operational cost, the tablet PC is set to become a stable fixture across the utility sector, especially out in the field and on the front line of service.

In this exclusive interview with Motion Computing's UK Supremo Ian Davies about his time in the industry, the changes he has seen and what he thinks the future holds for mobile computing...

FSN: What was the first piece of technology that made a huge impression on you? 

ID: Probably the first piece of technology, aside from the ubiquitous mobile phone or laptop that made an impression on me, was a touch screen device made by one of my previous employers that combined the Palm Pilot with a barcode scanner, essentially the pre-cursor to the rugged PDA that we know today.  I used to have it synchronised with my email, diary and address book on my PC, but as part of my job as a pre-sales consultant I could run Field Service or Retail supply chain ‘Apps’, although I guess they weren’t known as ‘Apps’ in those days.  My wife-to-be and I were in the wedding list service department of a well-known department store. 

I’ll never forget the contrasting looks I got from my wife and the sales assistant as we were handed such a device and I was asked if I knew how to work it.  At which point, with a cheesy grin I got my device out of my pocket.  Mine happened to be ‘marketing’ issue version that was made from clear plastic rather than the industrial grey, so it looked a bit flash too.  My fiancé was sighing in despair at my geekyness and the sales assistant was astonished that I knew how to use it, let alone owned one!

FSN: Do you think that the consumerisation of mobile devices has led to a major shift in the design of field service hardware?

ID: Undoubtedly there is far greater awareness of options such as tablets due to the consumer units now available - especially in businesses where there was a reliance on handhelds or laptops in the field.  Likewise, from a design perspective there is an increased demand for usability and the goal is to deliver a consumer grade experience whilst out in the field - a serious point given the potential increase in productivity.

FSN: What are your thoughts on the BYOD trend in field service organisations – do you see this as a major threat to your business.?

ID: BYOD in field service will likely hit a serious issue - consumer devices are simply not able to take the knocks that happen every day out in the field.  This then causes lost productivity, employee dissatisfaction and of course, presents the IT department with a host of OS’s to support.  Field service is one of the key industries where it will make far more sense to issue standardized pieces of equipment with training on how they should be handled to maximise the ROI.

FSN: What is the most exciting/unusual application of ruggedised devices you have seen?

ID: In terms of demands on us as a supplier of the actual tablets, the use of tablets for field based drug testing by Cambridge Cognition sticks out.  Likewise the use of the tablets for live audio mixing at concerts or remote controlling drone aircraft for surveys are all far removed from the usual applications associated with ruggedised devices.

FSN: With the rise in computational power of tablet devices do you think we are seeing the final days of the laptop?

ID: Though the increases in computing power do play a role, I think the greater factor that is leading to drops in laptop sales is far more simple - tablets are easier to use and a lot more intuitive.  They correspond much more to the mobile phones that we all own and as such people are very in tune with how to work a tablet - even down to the software available for them.  We are definitely seeing a swing away from rugged laptops towards rugged tablets for field service applications.

FSN: What is the biggest trend in devices that you are seeing come to the market currently?

ID: Right now the top demands are usually around usability features - improvements in input, display and battery life are all helping the multi-use capability for organisations and users.  Rugged Tablet PCs combine the performance of a laptop with the mobility of a rugged PDA – reducing the number of devices a user needs to carry and the IT Department’s number of devices and operating systems they need to support.  Aside from this, the regular demands are actually about enhancing the workflow by mobilizing the software and apps as opposed to just the hardware.

FSN: What do you think the next big technological advancement in mobile computing will be?

ID: That is the exciting thing about technology!  It is constantly evolving, the next great thing always around the corner.  Trends we’ve seen include more intuitive, more intelligent interacting with the mobile device such as voice and touch input.  There is obviously a great deal of competition for improvements to operating systems and another area we are seeing big developments in is around increased security of data. 

The idea of technology is to simplify lives/work, not make them more complex so contactless technologies such as RFID, NFC and Zigbee are becoming more main stream as ways of collecting and interacting with data.  There are a lot of concurrent changes happening right now and any one of these could yield substantial opportunities. However I think the dominant force right now is customer feedback into mobile apps and the emergence of professional, enterprise mobility.

FSN: You also offer a range of in vehicle solutions… driver safety is a major concern for the field service industry currently, do you think dashboard mounted devices can potentially distract a driver and cause accidents? 

ID: This is actually solved pretty quickly and easily - screen blanking technology exists to ensure that a driver cannot be distracted by a docked unit while the vehicle is moving.  Likewise the technology is clever enough that should the same mounted device be needed to be operated by a front passenger and is swung away from the driver, full access to the device can be obtained maximising ‘appropriate’ productivity whilst mobile.  These are critical concerns as safety will always trump productivity.  At present we are seeing a lot of innovation in this area coming from the Field Service and EMS sectors specifically and we have learnt a great deal so far.

FSN: You personally have been involved in this industry for about a decade – what is the biggest difference between when you started in the industry and today?

ID: When I first started, enterprise customers would gladly spend several thousands of pounds per device for then, leading edge technology capable of and designed to do single and often simple, but important tasks.  Adoption by users though was challenging.  Limited computer skills amongst users meant the technology was reluctantly used in many cases, and required significant investment in training as part of the overall project. 

Today devices can do so many things and have so many technologies built in to them that you might think there would be greater reluctance to overcome, but probably the biggest difference now compared to 10 years ago is the rapid adoption of the technology by the users. Personal IT knowledge honed from using technology at home or in their smartphone on a daily basis not only helps them embrace the technology changes their employers are adopting but they are continually pushing their employers to adopt new technologies to improve efficiencies and productivity like never before.

FSN: You have worked with a number of leading hardware providers to the field service industries, including Motorala, Intermec, Honeywell. What was it that drew you to Motion Computing and what sets them apart from their competitors?

ID: Traditionally, the technology I had been involved with prior to joining Motion was very application specific.  With the adoption of Tablet technology in the consumer space and the desire for organisations to do more with a mobile device, the opportunity in this ‘new’ wave of point of activity computing was a huge attraction for me.  I say ‘new’, but for nearly 13 years Motion has been leading the development in computing for users who were standing or walking, so I was confident they had something good going on!  The piece that really made sense to me though was the range of peripherals that Motion brings to the table to specifically suit the Enterprise Field user’s workflow. 

To use one of my colleague’s phrases, “it’s not all about the tablet”, and that is where Motion excels.  From a hardware perspective, charging, mounting, carrying and storing mobile devices is key to user adoption, and corporate responsibility for the vehicle based mobile user is an ever increasing requirement that Motion has really stepped up to.  Providing complete hardware solutions that truly offer point of activity computing sets Motion apart.
