4 Case Study: BPO in Energy Sector

This section summarizes the design, content and results of a case study on business

process outsourcing which was performed in the utilities industry. The purpose of the

case study was twofold: On the one hand we intended to study business process

outsourcing and the options to use crowd sourcing in a real-world context in order to

understand the specifics of this area. On the other hand, we wanted to analyze the

factors identified in the literature study in the context of the case study data. The

question to investigate is whether the case study indicates that the factors really can be

considered as affecting the decision on business process outsourcing into the crowd.


Case Study Design

In order to investigate the field of business process outsourcing, we had the possibility

to study a business services provider from the energy sector. Within this business

service provider (BSP), we collected information about BPO in several ways:

• One researcher worked during 3 months two or three working days every week at

the BSP’s facilities. The researcher was part of the team operating the business

service and maintaining the SaaS platform used for provisioning the services to the

service provider’s clients. The researcher maintained a work diary and collected

information about the work processes, technologies used and practices by observing

the co-workers and taking notes. The management of the BSP agreed to this procedure and the co-workers were informed about the purpose of the data collection.


K. Sandkuhl et al.

• The BSP specifies the services to be provided to the clients by defining business

process models. These models have to be kept accurate and up-to-date since they

are used to create executable workflows. Some of the models were accessible to the

researchers and could be analyzed.

• The internal business processes at the BSP, which were performed for delivering the

business process service to the clients, were captured by interviewing different roles

in the BSP. The roles interviewed were the service owner (responsible for the

features of the service and the flow of activities in it), knowledge worker (performing manual activities in the process), system operator (responsible for configuring and managing the infrastructure platform) and the BSP manager

(responsible for acquisition of clients, analyzing their demands and setting up the

service level agreements). In total six interviews were performed as expert interviews [2] guided by a list of questions related to the propositions (see below).

The main subject to investigate was “How are BPO services delivered by a BSP to

its clients in terms of processes performed, organization structure used, technology

applied and information used”. As already indicated in Sect. 2, the character of the case

study is descriptive. Furthermore, we defined two propositions P1 and P2.

• P1: The case shows the potential for outsourcing some of the tasks performed

within the BPO services to the crowd.

• P2: Factors identified in the literature study can be observed in the case study.

To set clear boundaries for the case we defined that only data collected during the

three months work of the researcher (see above) at the BSP’s facilities (including the

process models and interviews) in the organization units responsible for service provision to clients in the energy sector and for SaaS maintenance shall be taken into

account. Not subject of the case study are other organization units of the BSP, BPO

services provided to other utility industries (water, gas, etc.), the clients of the BSP and

sub-suppliers used for BPO by the BSP.


Summary of Case Study Data

Due to the space limitations only a summary of the data collected in the case study can

be presented in this paper. In this summary, we inserted the codes defined for the

factors (see Table 1), e.g., [FLEX] for the factor “flexibility”, if the information collected can be linked to the factors. This “linking to codes” will be used in Sect. 4.3

when evaluating the case study data.

The BSP studied in the case study is a medium-sized enterprise from Germany

which offers more than 20 different BPO services to their clients. The target group for

these services is medium-sized utility providers and other market roles of the energy

sector in Germany and several other European countries. Many energy distribution

companies are outsourcing some business functions and business processes connected

to these functions. Examples are meter readings, meter data evaluation, automatic

billing, processing and examination of invoices, customer relationship management

and order management. The motivation of these companies for outsourcing business

Crowdsourcing in Business Process Outsourcing


processes is twofold: Some companies use BSP is to temporarily increase the capacity

for performing the processes, as they do not have sufficient internal resources for

certain high capacity periods [FLEX]; others want to minimize efforts for adaptation to

market or legal changes [COST]. Energy companies in Germany are facing a continuously changing business environment due to new regulations and due to competitors

implementing innovative technical solutions, like intelligent metering or grid utilization

management. In this context, both the business processes in organizations and information systems supporting these processes need to be quickly adaptive to changing

organizational needs [FLEX].

The BSP offers the performance of a complete business process for a business

function or only of selected tasks of a business process. In this context, the BSP has to

offer and implement solutions for different variations of these business processes or

tasks. One variation is inherent in the business process as such. Even though core

processes can be defined and implemented in standard software systems, configurations

and adjustments for the organization in question are needed. The second cause of

variation is the configuration for the country of use, i.e., the implementation of the

actual regulations and bylaws. The third variation is related to the resource use for

implementing the actual business process for the customer, i.e., the provision of

technical and organizational capabilities.

The IT-basis for these services in our case study is a software product which was

developed and is maintained by the BSP. Integrated with a workflow engine and

business activity monitoring, this software product provides the business logic for the

energy sector, which is implemented using a database-centric approach. In addition to

this software product, other cloud-based services for information exchange, document

management and security are integrated [CPLX]. Different deployment models are

used including a provider-centric model (the software product and the business processes are run at the BSP’s computing center), a client-centric model (the software

product is installed at the client site and the manual work of the business process is

performed at the BSP) and mixed models (e.g., the software product is offered in the

cloud, work and process are performed partly at the client and partly at the BSP)


An example business process, which is offered as BPO service and consists of

various activities [DECO], is to process information about energy consumption based on

meter readings. This information is exchanged between different market roles in the

energy sector using EDIFACT-like messages. Each file exchanged between the market

roles might contain thousands of messages which in turn follow a defined syntax with a

multitude of constraints and rules regarding the semantics of the information included.

The processing of the files and messages is only a small part of the process. More efforts

and activities are caused when errors are detected in the messages or exceptions are

discovered due to violation of constraints and rules. In these cases, the automatic processing is interrupted and human intervention required. The competence required from

the “knowledge workers” ranges from simple correction of syntax errors or substitution

of faulty codes to remedy of so far unknown exceptions which requires expert knowledge from the energy sector and the IT services used. This expert knowledge is considered as one of the most important competitive advantages [COMP].


K. Sandkuhl et al.

BSP and client have an agreement which defines the capacity to be provided, the

cost model, levels of confidentiality [SECU] and service quality. The BSP is responsible for providing the contractually agreed capacity and quality. Sub-suppliers will

only be integrated if the agreement with the client does not exclude this option [SECU]

and if they provide the required quality of the service [QUAL] [RISK]. So far, no

experience with crowdsourcing exists. The BSP can imagine evaluating crowdsourcing

techniques for specific, isolated tasks [INTA] with low training efforts, like the correction of error codes, when there is a lack of own capacity [FLEX]. Precondition

would be the availability of a defined group of people with known competences

[COMP] [CMAV] who flexibly could be integrated into service provision. Furthermore, the status of the contributions from the crowd should be transparent [CTRL] and

it should be economically rewarding [COST].

The maintenance process encompasses steps for designing, developing, deploying

and operating the software systems used for BPO. The case showed three different

phases in the maintenance process:

• The conceptual solution addresses the development of business services which fit to

the strategic objectives and meet the practical demands of the customer under

consideration. Focus here is on the business logic, not on the technical implementation [COMP].

• The technical solution prepares the conceptual solution for execution. This usually

requires an enhancement or refinement of the conceptual solution when adapting it

for a specific technical platform for execution [CPLX],

• The executable solution represents the technical solution deployed on a specific

platform. This “running system” is managed by the customer that uses it or by a

service provider [DEPL].

The technology stack encompasses all IT-tools and platforms requires for the above

phases of the engineering process. This includes tools and notations or languages for

modeling the conceptual solution, like process modeling, business process management

or enterprise modeling tools, workflow engines and process execution environments as

well as software development environments in case services or software components

have to be integrated, and operating platforms and monitoring tools used during execution of the solution [CPLX].


Case Study Analysis

The main technique for analyzing the case study data was to link the data to the

propositions. Thus, we will discuss both propositions in the light of the case study data.

As both propositions are related to the factors identified in Sect. 3 and summarized in

Sect. 3.3, we will start the analysis by providing an overview what information is

visible in case study data regarding the factors. This summarized in Table 2.

For some factors, there was no or not enough information available in the case

study to decide on their relevance: ability to handle coordination of crowd workers,

availability of an own crowd platform to the organization and the required number of

knowledge workers to handle a given case.

the BPO services to the crowd. Both the case study data and the evaluation of factors in

provisioning the BPO service. The potential for crowdsourcing seems quite limited

since it is only for “simple” tasks in exception handling which require limited training

efforts for a known group of crowd-members. Furthermore, the BSP does not have

experience with crowdsourcing and will consider this as an “experiment”, which

indicates that the subject so far is given low priority. However, for the research work

presented in this paper it is important to notice that due to the potential for using

crowdsourcing it was a suitable case study for investigating the factors identified in the

literature study.

P2: Factors identified in the literature study can be observed in the case study.

Table 2 shows that most of the factors actually could be observed in the case study and

most of them were confirmed relevant. Only two factors were not confirmed:

deployment model and ease of task decomposition. For these two factors, which

intuitively make sense, we will need to investigate further cases in order to decide on

their pertinence.

5 Summary and Future Work

Based on a literature study in the areas of BPO and cloud computing and crowdsourcing, this paper identified potential factors relevant for decision making in favor or

against using crowdsourcing in BPO scenarios. The factors identified were investigated

in a case study from business process outsourcing, which confirmed many of the factors

and gives reason to believe that the work contributes to a better understanding of

outsourcing decisions in BPO and the relevant factors. However, just one case study

will not give a conclusive picture whether the identified factors can be assumed to be

relevant for the majority of BPO cases. Future work will have to investigate more

cases. The factors identified have to be considered as a theory contribution grounded in

literature and one case study.

Research including empirical studies has threats regarding its validity, and so has

the case study performed in this paper for investigating the decision factors for crowd

sourcing. However, to early identify such threats and to take actions to mitigate the

threats can minimize the effect on the findings. Common threats to empirical studies are

discussed, for example in [20] and [23]. The threats to validity can be divided into four

categories: construct validity, internal validity, external validity and conclusion

validity. Construct validity is concerned with obtaining the right indicators and measures for the concept being studied. Internal validity primarily is important for

explanatory studies with the objective to identify causal relationships. External validity

is addressing the question about to which extent the findings in a study can be generalized. Conclusion validity addresses repetition or replication, i.e., that the same

result would be found if performing the study again in the same setting.

With respect to construct validity, the following threats were identified and actions

taken: (a) Selection of employees from the BSP interviewed and observed in the case

study. The results are highly dependent on the people being interviewed and observed.

Only persons experienced in business process outsourcing and the application domain

under consideration will be able to contribute to judging the importance of factors. To

obtain the best possible sample, only people having worked in this area for a long time

Crowdsourcing in Business Process Outsourcing


and hence having the required background were interviewed or observed during the

case study. (b) Reactive bias: A common risk in studies is that the presence of a

researcher influences the outcome. Since the selected participants in the study and the

researcher performing the study have been collaborating for a long time, this is not

perceived as a large risk. However, as the crowdsourcing idea was proposed by the

researcher there is the risk that the interviews are biased towards this idea and to find

evidence for the relevance of factors. In order to reduce this threat, the interviewees

were informed that crowdsourcing can be used in different ways and the purpose of the

study was to investigate feasibility. (c) Correct interview data: There is a risk that the

questions of the interviewer may be misunderstood or the data may be misinterpreted.

In order to minimize this risk, the data collected during the interviews was presented

afterwards to the interviewees to allow for verification. Furthermore, the interviews

were documented, which allowed the researcher to check certain parts of the interview

again if portions seemed unclear.

From the perspective of external validity, a potential threat of the study is of course

that the actual interviews and observations have been conducted with members of only

one BSP. It will be part of the future work, to conduct a study with other BSPs.

Conclusion validity mainly concerns the interpretation of data: The outcome of the

study potentially could be affected by the interpretation of the researcher. To minimize

this threat, the study design includes capturing the relevant aspects by different data,

i.e., to conduct triangulation to check the correctness of the findings. Furthermore,

another risk could be that the interpretation of the data depends on the researcher and is

not traceable. To reduce the risk the data interpretation was discussed with other

researchers and validated by them.

In addition to more case studies and the collection of additional data regarding the

identified factors, future work has to contribute a deeper conceptualization of the

different factors. We identified factors and confirmed their pertinence in one case, but

we did not fully operationalize them. For factors like architecture of cloud service, we

will need to spend more work on finding indicators which show, when the factor under

consideration has substantial influence and when the influence is negligible. For the

example of the factor “cloud service architecture” this would mean to determine, with

which indicator to measure this factor and what indicator values would have to be

considered too high for a decision in favor of outsourcing. Another direction of the

future work is to separately evaluate each factor’s influence for different crowdsourcing

models, as the employed model (e.g., microtask markets, solution contests) may affect

factor’s relevance.
