Logging And Monitoring Technologies: How To Buy And Why
BY JACKIE WIEDNER, NICE SYSTEMS LTD.
Every customer contact center has a number of reasons to record transactions. Think
your call center may be different? Ask yourself the following questions.
- Is your organization subject to compliance requirements from any level of governmental
or regulatory agency?
- Is it important that you limit risk or liability regarding transactions or the exchange
of information?
- Are you concerned about the quality of service your agents provide your customers?
- Is the customer experience important to your company's strategic goals and its bottom
line?
It's a good bet that most or all of these requirements apply to your situation. In
today's business environment, all companies are focused on providing superior customer
service...or should be. If you intend to purchase recording equipment to address these
issues, it's best to start by defining the objectives of your call center.
Are you selling something or providing a service? Are you providing information or
offering customer support? Are money or other assets being transferred? Or, is your call
center performing all of these activities? Recording these events satisfies a number of
objectives, all of which fall into two categories: "transaction verification"
and "quality monitoring."
Transaction Verification
This category applies especially to financial industries such as banking,
investment and insurance and firms trading in securities, commodities, utilities and other
financial instruments, all regulated by the NASD and the SEC. Recording not only helps
meet the compliance requirements set out by the NASD and the SEC, it also protects the
bank, as well as consumers and investors, by being able to settle disputes quickly and
definitively.
Transaction verification is important in a wide range of other industries, among them
telecommunications, where the FCC closely regulates corporate interactions with consumers.
For example, when consumers are asked to switch from one long-distance service provider to
another, that decision to switch must be verified by a third party. Recording consumer
transactions in compliance with requirements set out by the FCC can eliminate accusations
of baiting and switching.
Reducing Company Risk
There are many more examples that show the importance of transaction
verification. For instance, one of the largest North American suppliers of ready-mix
cement records phone orders specifying the volume and grade of cement. Imagine how much
money is at stake when thousands of tons of pre-mixed cement arrive on a job site and
its the wrong grade? For this company, its essential to determine who made the
mistake.
Savings In Liability
Insurance Costs
Insurance providers recognize the value of using voice recording and, therefore,
its a widely accepted practice in the industry. Many insurers save considerable sums
on liability insurance once voice recording is employed. For many businesses, owning a
voice recording system is not unlike owning a building security system or a home security
system. Voice recording systems can pay for themselves in just two years, based solely on
liability insurance cost reduction.
Quality Assurance
The demand for quality assurance has fueled significant growth in call centers
today. Datamonitor predicts a compound annual growth rate of 60 percent for quality
assurance solutions to the year 2003. Not only are corporations recording samples of
conversations between agents and customers, they are also looking at agent-PC interaction
via desktop screen capture. By providing technology that can replay synchronized voice and
screen sessions, todays quality management systems can recreate the entire agent
session. They also provide online evaluation and automated reporting to pinpoint call
center training requirements.
How To Buy
Once you have confirmed the need to record by identifying what to record, how do
you select the right solution? Different recording techniques satisfy different
requirements. Heres a general breakdown of recording options.
- Full-time recording (or logging) records all the calls, all the time. This
method best applies to compliance and verification industries such as banking, trading,
insurance, utility, etc.
- Selective recording, or recording some of the call, some of the time, applies to
verifying specific transactions that can be scheduled, but not all consumer interactions.
It is also known as event-based recording.
- Recording on demand (ROD) is initiated by the agent or supervisor and applies to
verifying specific transactions.
- Quality monitoring involves gathering a representative sample of call agents voice
and screen sessions for performance evaluation.
It is also important to know that there are three major options in which a voice
recorder can interface with your system for recording.
- Trunk side means the recorder is directly connected to the trunks leading into the
PBX/ACD. It applies best to full-time recording of all agents.
- Extension side records from the phone extension and can be analog or digital. This
application works best with full-time recording of specific extensions.
- Service observation recording is performed via a dedicated recording connection using
the service observation feature. The supervisor typically uses the service observer port
to conference into agent calls. This application works best with selective recording and
quality monitoring because it permits a small percentage of calls to be recorded and
requires fewer channels to record all agents.
The CTI Factor
Computer-telephony integration (CTI) allows voice recorders to make intelligent
decisions about when and what to record. With CTI, voice recording systems can
tag calls with additional information to facilitate location and retrieval.
The ACD provides real-time information to the recorder via the CTI server. This includes
call details such as dialed number identification service (DNIS) or Caller I.D. (ANI, or
automatic number identification), IVR (interactive voice response) activity, agent I.D.,
position and extension. Any of these can be used as a parameter for initiating voice
and/or screen recording, as well as conducting specific queries for retrieval. For
example, you can choose to record all calls routed to agent Smith (wherever he may be
seated) coming in from a specific toll-free number. One week, one month or even one year
later all those calls can be retrieved using the same parameters.
We can think of CTI as the glue that binds a variety of call center applications within
the computer-telephony environment. These applications can include IVR (interactive voice
response) units, intelligent call routing, screen pop and predictive dialers. CTI also
allows these applications to use corporate databases. For example, customer codes from a
corporate database can be linked to telephone calls. This allows the user of a CTI voice
recording application to search for all calls related to those data, such as customer
account numbers or Social Security numbers.
Enough Storage, When You Need It
Another key area to consider when determining your recording solution is storage.
You need to determine how much storage is required for online, immediate access, and at
what point you start to archive your data. Archived data can take longer to retrieve
because the tape may need to be placed in the logger for playback. However, a good
archival system will tell you, after you enter your search parameters, exactly which tape
to insert into the logger.
You will need to have a good idea of the number of lines and the expected volume of
calls the voice logger will be recording. It is also important to determine the time frame
of calls youre most likely going to need to retrieve.
In a full-time recording environment, there are commonly two peak periods
in which high volumes of recorded calls must to be retrieved and verified. For example, a
utility will experience a peak period after the monthly billing is mailed, due to customer
inquiries about their bills and the need to verify the original conversation. The second
peak period occurs at year-end when, for example, equal-payment billing is reconciled. In
this scenario, it would be most efficient to have at least one month of calls online for
immediate access and then have a library of archived tapes ready for the year-end peak
period.
Depending on the compression ratio, you can have thousands of channel hours online for
immediate access. To determine your online requirements, you can use simple math. Multiply
the average number of calls per agent times the average length of call, times the number
of agents, times the number of days you will require immediate access.
The latest technology has significant capacity for hard disk storage; i.e., up to 105
GB or 38,000 hours online.
One way to increase immediately accessible audio is a multi-DAT auto-changer, which
allows a number of DAT tapes to be inserted into the logger. A 6-DAT auto-changer, for
example, allows up to 25,000 hours of unattended recording, all accessible without manual
intervention.
After defining your online storage requirements, you can then choose your archiving
needs.
Archiving
There are currently two common methods of storage for todays voice loggers:
digital audio tape (DAT) and magneto optical (MO) disk. A typical DDS-2 DAT tape holds
about 500 channel hours, while the DDS-3 will hold about 1,500 hours. Proprietary
compression techniques offered by independent vendors will allow you to multiply this
ratio significantly. Another archiving media option on the market is AIT (advanced
intelligence) cassette. The AIT cassette has a capacity of 25 GB per cassette, while the
double-sided MO offers 5.2 GB, or 2.6 GB per side.
Recording The Right Calls
Due to the nature of selective recording, fewer channels and less disk space are
needed to record specified calls or perform quality monitoring. This is because recording
can be scheduled according to various criteria, including specific agents or extensions,
CTI events, call direction, length of call, and in the case of quality assurance, number
of calls per representative, wrap-up time, etc. Calls that do not meet your criteria are
not recorded.
When monitoring for quality, supervisors have a limited amount of time to review agent
calls and may record and evaluate between five to ten calls per representative per month.
Therefore, since a select number of calls are being recorded, fewer channels are needed
for quality assurance recording.
Choosing The Best Screen Capture Technology
The single most important factor when choosing a screen capture technology is the
overall impact that screen recording will have on network bandwidth. The second most
important factor is detectability. If agents experience screen slow-down due to
monitoring, they will be alerted to the monitoring session and may modify their behavior.
Screen recording solutions that take continual snapshots of agent desktop activity, known
as screen scrape technology, require a tremendous amount of network bandwidth
and can easily overload most networks and/or slow down agent applications. Screen capture
technologies that record only the deltas, or changes to the screen, have a much lower
impact on network resources and are undetectable to the agents.
What To Look For In A System
Weve discussed the need to record and the tremendous growth in the
importance of quality assurance recording. Weve also touched on the various
technologies available to meet call center logging needs. Following is a checklist of
points to consider when weighing different recording equipment options.
A scalable solution with an open architecture. When you shop for a recording/quality
assurance system, look for one that is scalable in both hardware and software so it can
grow with your call center. Also, ensure that applications are ODBC-compliant and can be
integrated with, as well as upload, your current databases.
Flexible recording platform. As your call center grows, your recording needs will vary
and expand, and you will need a vendor that can support full-time, selective, ROD, quality
assurance and screen capture recording on one logger platform. In the future, this
recording solution should accommodate different types of recordable media such as e-mail,
fax, IVR, instant text chat and others.
Integration capabilities with the leading ACDs. Your recording solution should
integrate with the leading ACD providers and preferably be built around a technology
partnership between the logging/quality assurance provider and the ACD vendor. Equipment
grounded in this relationship will help guarantee that any changes to your ACD technology
will not impair your ability to perform logging and quality assurance operations. The same
holds true in choosing CTI products choose equipment that will allow for change and
growth without sacrificing any logging and quality assurance functions.
Computer-telephony adaptability and migration to different applications. Look for a
logging/quality assurance application that has API (application programming interface)
capability and will allow integration, now and in the future, to the specialized
computer-telephony applications in your call center, such as predictive dialers, IVR and
others.
Adaptability of quality assurance solution to existing quality assurance programs.
Nearly all call centers are implementing some form of quality management, even if
its a paper-based, live service observation. For this reason, call center managers
and reviewers are likely already comfortable with a certain process. Your quality
assurance application should offer the capability to automate these processes and
significantly reduce reviewer workload without forcing your quality assurance department
to adopt entirely new practices.
Screen capture technique and your LAN. Look for a data capture application that has low
impact on network bandwidth and is undetectable by the call agent when a monitoring
session begins.
Archiving, redundancy, alarms and security. In mission-critical logging scenarios, look
for robust loggers with a high fault tolerance, advanced system alarms and, in the event
of failure, either hot-standby or redundancy capability. In environments where data
preservation is critical, remote archiving is a must. Also, look for logging applications
with sophisticated, multitiered security access you want system access controlled,
but you dont want this process to be cumbersome.
Future Call Center Technologies
Call centers are rapidly evolving into contact centers, funneling all methods of
communication into a single entry point. Voice, e-mail, Internet and chat boards are
combined into a single contact record for each individual customer. As bandwidth to the
desktop has become broader and more sophisticated, call centers have rapidly deployed
single point of contact technology, allowing customers to communicate their requests
through any of the media mentioned above. The single point of contact trend is
also the direction in which recording technologies must evolve. It will involve voice over
Internet Protocol (VoIP), a purely digital data recording system that allows all
communications media to be combined, and it will redefine the purposes of recording.
A Partner For Success
Not surprisingly, the single most important decision is choosing the right
partner. While its important to be aware of all of the above, your solution provider
should be able to walk you through the entire process, determining the right solutions and
configurations for your company. When seeking a solution provider, you should look for a
proven track record and references to substantiate technical and integration expertise,
research and development resources for future applications, training, consulting, support
and user services. These factors will point you toward protecting your investment over the
long term.
