How optimization and simultaneous electronic support of actual laboratory<br />
processes can boost efficiency<br />
Ulf Fuchslueger<br />
<strong>Introducing</strong> a <strong>Paperless</strong> <strong>Lab</strong><br />
<strong>Lab</strong>oratories working in the<br />
pharmaceutical industry in<br />
the areas of R&D and quality<br />
control find themselves<br />
increasingly having to cope with<br />
conflicting demands — tougher regulatory<br />
requirements and harsher economic<br />
realities. In order to meet these<br />
demands, new ways of dealing with<br />
process, data and system management<br />
are necessary. This article shows how<br />
the paperless lab (as an integrated<br />
process, and not as a system implementation)<br />
can meet these challenges<br />
and boost efficiency.<br />
WHY NEW CONCEPTS<br />
FOR LABORATORY DATA<br />
MANAGEMENT?<br />
On the one hand, the authorities<br />
require more data with more quality,<br />
such as with the new EU GMP<br />
Annex 11 and the more intensive FDA<br />
inspections regarding 21 CFR Part<br />
11. And, on the other hand, there are<br />
the commercial pressures requiring<br />
more data in less time, typically with<br />
the same level of staff or less. On top<br />
of that, advances in technology and<br />
laboratory equipment mean that even<br />
more data is being generated faster,<br />
which creates almost insurmountable<br />
obstacles for conventional<br />
documentation and datamanagement<br />
processes in<br />
regulated laboratories.<br />
These obstacles, in turn,<br />
causes bottlenecks<br />
for the development and approval<br />
processes.<br />
THE ROOT OF ALL EVIL:<br />
HYBRID SYSTEMS<br />
When you look at data management<br />
in the lab, what you usually<br />
see is a mixture of various independent,<br />
non-integrated data-processing<br />
systems on paper and in electronic<br />
form. Often, paper is the preferred<br />
documentation medium when you<br />
have a mix of countless computer-<br />

*With the exception of the documentation and control effort, all numbers<br />
refer to the approval or analysis of one batch. Quality-relevant<br />
transfers have a direct impact on the result; redundant data transfers<br />
provide references and cross-references.<br />
ized systems, such as analyzers, offi ce applications<br />
and higher-level systems like laboratory information<br />
management or enterprise resource planning<br />
(ERP) systems. Such a scenario results in producing<br />
a hybrid system with numerous media gaps — this<br />
is the real root of all evil, leading to ineffi ciencies,<br />
quality and compliance risks and unnecessarily long<br />
throughput times, which prevent businesses from<br />
hitting their targets.<br />
Table 1 shows the typical key performance indicators<br />
of such a laboratory. The high level of quality<br />
risk (due to the high number of manual<br />
data transcription steps) is countered<br />
with extensive control steps — but<br />
that results in less effi ciency and longer<br />
throughput times. The use of isolated<br />
systems prevents the timely transfer<br />
of information, which leads to further<br />
unforeseeable delays and additional costs.<br />
And last, but not least, it can result in a considerable<br />
amount of the enterprise’s intellectual capital<br />
being wasted. The cost of using various isolated<br />
systems to collect data for modern knowledge-management-systems<br />
(statistics, data mining, reporting,<br />
exception handling, etcetera) is simply too high. So,<br />
much knowledge that could be extracted from the<br />
data collected remains untapped.<br />
In the industry, there are three different approaches<br />
to addressing this root problem. The fi rst — and<br />
actually no real solution — is the optimization of the<br />
existing hybrid system by adapting the existing processes<br />
and systems. It goes without saying that such<br />
an approach only brings selective and slight improvements.<br />
The second is the introduction of electronic<br />
documentation systems (often described as electronic<br />
lab notebooks) that show the paper data in electronic<br />
format. While the introduction of such a system<br />
brings certain benefi ts for quality and compliance<br />
purposes, the real problem is simply transferred from<br />
paper to an electronic format (“paper on glass”) and<br />
the hoped-for gains in effi ciency are only very small.<br />
And the practicality of introducing electronic documentation<br />
into the laboratory (using tablet-PCs or<br />
other mobile devices) is highly questionable. The third<br />

approach, which we discuss in more detail below, is<br />
the optimization and simultaneous electronic support<br />
of the actual laboratory processes — the introduction<br />
of the paperless lab.<br />
THE WAY TO A PAPERLESS LABORATORY<br />
Since introducing a paperless laboratory involves<br />
more than simply implementing another IT application,<br />
the procedure model we use here takes into account<br />
other perspectives in order to build a sustainable<br />
overall concept. These perspectives fall into three main<br />
areas — the business needs, the user’s needs and the<br />
technical perspective.<br />
The business point-of-view defi nes the project’s<br />
goals and vision and ensures that the introduction of<br />
the paperless laboratory complements the company’s<br />
overall business objectives. Typical goals for producers<br />
are increasing net cash fl ow, reducing development<br />
time and, thereby, generating additional sales or<br />
reducing warehousing and stock costs to free up more<br />
capital. Naturally, various other goals or combinations<br />
of targets are possible — but what is decisive is that a<br />
quantitative connection can be made between laboratory<br />
activities and business objectives. This is achieved<br />
by defi ning a business-specifi c cause-effect model and<br />
implementing it into a corresponding fi nancial model. 1<br />
That is the only way that you can ensure<br />
that the implementation project meets the<br />
company’s targets and that the cost-benefi t<br />
analysis accounts for all relevant factors.<br />
The user’s point-of-view is the central<br />
element to developing the paperless<br />
laboratory concept. Based on a thorough<br />
process and system analysis, the user’s per-<br />

categories; the documentation and control categories could be<br />
substantially reduced by the introduction of a paperless laboratory.<br />
Figure 2: Distribution of non-process activities per department as a<br />
percentage of work hours.<br />
spective will be summarized in the form of process descriptions and data streams. As well as the<br />
actual laboratory procedures — such as sample fl ow and processing, supporting processes will<br />
also be mapped (such as apparatus maintenance, reference substance management and reagents)<br />
in actual state. For every process step, information will be collected from any systems used, any<br />
responsibility changes and any data inputting and outputting. Key performance indicators will be<br />
collected from the process analysis for later integration into the fi nancial model. Vital interfaces<br />
with higher-level processes will be analyzed and documented. The analysis process is also the<br />
foundation for the subsequently conducted multi-moment analysis — a methodology that allows<br />
quantitative information to be derived from and for processes.<br />
Multi-moment analysis 2,3 provides statistically sound and accurate information about the use<br />
of resources per process step or sub-step — and for all processes. To collect data, every laboratory<br />
worker is equipped with a mobile device or PDA (confi gured for their particular tasks) that<br />
requires them periodically, but randomly (on average every 20 minutes) to select the task they are<br />
currently performing from a list. The impact of multi-moment analysis on the workfl ow is minimal,<br />
because just a simple click suffi ces — no recording of times or other parameters is required.<br />
Over a typical period of two weeks, suffi cient data is collected to enable highly detailed statistical<br />
analyses to be made on costs, time and clustering for processes, process steps and task categories.<br />
Figures 1–3 show examples of various evaluations from a multi-moment analysis. The multimoment<br />
analysis not only allows processes (independent of whether a new system is introduced<br />
or not) to be optimized where the greatest need or benefi t lies, but also permits the work stages<br />
to be categorized — thereby enabling a quantitative assessment of the potential benefi ts that the<br />
implementation of a paperless lab would bring (Figure 3). That, in turn, provides the foundation<br />
for a fact-based business case and for the comparison of various implementation scenarios and<br />
their economic benefi ts. The qualitative process description (together with the key performance<br />
indicators and quantitative statements from the multi-moment analysis) thus provides the crucial<br />
information for the paperless laboratory concept development.<br />
Taking the technological (i.e. IT and equipment) point-of-view — and looking at the existing<br />
infrastructure, company standards and long-term strategy — enables a comprehensive concept<br />
to be developed for the automation of the laboratory data-fl ow process. Only then will such a<br />
concept be in line with the company’s commercial targets.<br />
To develop the paperless lab concept — as well as considering the three perspectives outlined<br />
above — you also need a set of principles that allow for a defi nition of process targets based on<br />
the process description of the actual-state processes. The key principle and the vision of the paperless<br />
lab is the self-documenting process — a process that produces GxP-compliant documentation<br />
and eliminates unnecessary tasks from the workfl ow. That naturally means that manual<br />

data collection and transfer are eliminated<br />
wherever possible by interfacing to and from<br />
devices and systems — and where that is not<br />
feasible, by using barcodes for fast, error-free<br />
data collection. That also means that redundant<br />
or fragmented data is eliminated, that the<br />
“single-source-of-truth” principle is implemented<br />
and that data is available to every authorized<br />
user in real time. That, in turn, leads<br />
to improved processes, faster decision making<br />
and better teamwork.<br />
The application of these principles to the<br />
actual-state processes enables target-processes<br />
to be defi ned and functional requirements to be<br />
established. As part of the paperless lab concept,<br />
the delta between the current functionality and<br />
the required functionality will be generated in<br />
the gap analysis. This is the only way the fi lling<br />
of such gaps may be conceptually approached — naturally<br />
always considering the underlying business targets.<br />
Possible scenarios also include the modifi cation<br />
of existing IT systems by adapting existing applications<br />
to close functional gaps and multiple scenarios<br />
to close the remaining gaps with other applications.<br />
Once, the only kind of application specifi cally aimed<br />
at laboratory use was a laboratory information<br />
management system (LIMS). However, today there<br />
are many types of applications providing overlapping<br />
functionality. For example, electronic laboratory<br />
notebooks (ELN), sometimes for quality control<br />
referred to as laboratory execution systems or LES<br />
(derived from manufacturing execution systems or<br />
MES); archiving or raw-data management systems<br />
(scientifi c data management system or SDMS);<br />
specialized applications for device and system<br />

integration, increasingly also software that was not<br />
originally laboratory-specifi c, such as product-lifecycle-management<br />
(PLM) systems or ERP systems.<br />
Some software fi rms also offer combinations of the<br />
above-named applications, and there is generally a<br />
trend toward an extension and overlapping of functions<br />
or convergence of applications.<br />
There is no quick answer as to which application<br />
combination is the best for a company. But, by using<br />
SWOT analysis (strengths, weaknesses, opportunities<br />
and threats) to compare the various possible combinations<br />
— naturally accounting for the overall business<br />
targets and not just the needs of the laboratory — the<br />
selection can be reduced to one or two scenarios.<br />
The next step is to select suitable products to fi t the<br />
desired application combination for the developed<br />
scenario. With a sound concept, defi ned target pro-<br />
cesses and their functional requirements, that<br />
is a relatively easy undertaking. As well as the<br />
functional considerations, it is also necessary<br />
to consider the complexity of the IT landscape<br />
and soft factors, such as the readiness of the<br />
software suppliers to cooperate.<br />
Before making any fi nal selection — and to<br />
clear up any technical issues and to get prospective<br />
users involved at an early stage — it<br />
is recommended piloting the whole solution in<br />
small, well-defi ned stages. Such a pilot scheme<br />
— which costs little in terms of money and<br />
risk — should cover as many areas of the paperless<br />
laboratory as possible and helps fi netune<br />
the fi nal implementation planning. The<br />
implementation of the fi nal solution is made<br />
in accordance with widely accepted standards,<br />
such as GAMP. 4 Because the pharmaceutical<br />
industry is so highly regulated, the whole system<br />
must be validated to meet strict requirements. 5,6 The<br />
work invested in the procedure model (e.g. process<br />
analysis, concept development, setting target<br />
processes and piloting) pays off here, contributing<br />
toward the necessary documentation. It should not<br />
be forgotten at this point that the paperless laboratory<br />
is not just the introduction of a system, but is<br />
also — above all else — process re-engineering. It is,<br />
therefore, necessary to support the new optimized<br />
process landscape with all necessary standard operating<br />
procedures (SOPs) and guidelines to maximize<br />
the benefi ts of the paperless laboratory.<br />

approach, the benefi ts of the paperless laboratory<br />

compared to using a specifi c application (such as an ELN) are several factors higher.<br />
The automation of the data fl ow and the continued elimination of documenting and<br />
related control activities signifi cantly boost effi ciency for laboratory staff and management.<br />
Already through these effects alone, effi ciency gains of 20 to 30 percent are<br />
feasible (depending on a company’s situation).<br />
Additionally, the virtual elimination of manual tasks substantially reduces processing<br />
times and quality risk. System-specifi c automatic checks ensure compliance and data<br />
consistency and reduce control activities to atypical results (“review by exception”),<br />
thereby accelerating processes and improving resource allocation. Since automatic documentation<br />
also automatically generates numerous process-relevant parameters — such<br />
as throughput times for certain tasks, equipment utilization or sample logistics — there<br />
is an excellent source of data for laboratory management. The paperless laboratory<br />
delivers key performance indicators for its own continual improvement, free-of-charge<br />
— and enables the comparison of organizational units using high-quality data. And<br />
the availability of real-time data benefi ts other areas outside the laboratory — such as<br />
simplifying inter-departmental cooperation, supporting knowledge management and<br />
improving follow-up processes. From the users’ point of view, the paperless lab substantially<br />
simplifi es the workfl ow and reduces the number of systems implemented. It also<br />
supports user-specifi c portals and sharpens focus on what is important.<br />
It is clear that the sum of the paperless lab’s benefi ts is enormous. As with all investment<br />
projects of this size, after implementation, evidence should be presented to show<br />
that the estimated business case and the reality correspond. This can be done at any<br />
time with the help of multi-moment analysis, which can also be used to quantify the<br />
impact of any process change on the workfl ow.<br />
