BUSINESS PROCESS OUTSOURCING: LEVERAGING THE CLOUD Pushkar B Gokhale

Abstract:

In the early to mid nineties, Business Process Outsourcing (BPO) along with IT Outsourcing (ITO) became the new mantras for driving down costs as well as improving quality and efficiency. BPO has fast become one of the primary means of cutting back on costs and has also resulted in becoming a ‘Job-cow’ for emerging economies like India, China and Philippines. Companies of all sizes, large to small, and everything in between, have been outsourcing part of their business to service partners. By doing so, companies have been able to leverage economies of scale and inexpensive labor to increase their own margins. With the growing convergence of IT and BPO, outsourcing has become more dynamic and it has created areas of opportunity for service partners to provide better and innovative service offerings. Over the last two decades, different variations of outsourcing models have evolved, leading to various technological changes and upgrades. Cloud computing is seen to be the next big wave within outsourcing and has already seen major players like Amazon, Microsoft and Google leading the way into the “Cloud.” With the current push towards cloud computing becoming stronger, traditional methods of outsourcing and providing service will need to change. This white paper looks at the possible convergence of BPO within the ‘Cloud’ and whether BPO can leverage cloud computing.

Business Process Outsourcing and its Drivers

Typically, Business Process Outsourcing (BPO) can be termed as the handing over of non-critical work within a company to a third-party (Service Partners) who in turn takes responsibility to run the process, as per the stipulations and agreements between the parties.

Gartner defines BPO as "the delegation of one or more IT-intensive business processes to an external provider that, in turn, owns, administrates and manages the selected processes based on defined and measurable performance metrics." BPO can be divided into two main categories: Back office outsourcing and front office outsourcing. Typically, back office work encompasses internal functions where there is limited interaction with the end customer. Some examples would be finance or human resource related work. More often than not, these services have a limited ‘voice’ component to them, which means that if there is some interaction needed between the end customer and a back office representative, it is more often through written correspondence. In contrast to back office processing, front office outsourcing deals with functions which are end customer facing. Examples can be billing support, customer service and technical support. Here the responsibility of providing a high level of customer service overshadows every other aspect of operational excellence.

Figure 1: – Illustration of a few Back Office & Front Office Process types

In this ever increasing competitive environment, companies who are ready to outsource are searching for service partners who can leverage technology to not only improve existing systems but also to develop new ones. The need of software, hardware and resource maintenance is increasing at an exponential rate and this, in turn, has created a need for service partners to establish effective and efficient service offerings that transcend the traditional support services and look to provide a complete service landscape.


Below is the generic Service offering landscape showcasing different verticals & horizontal services.

Figure 2: Generic BPO Service offering Landscape

Another key component of outsourcing is the ability to service end customers as well as company clients from various locations. Initially, off-shoring (where work is taken out of the country and is done from another country which is typically far away) was the preferred option. Lately, there seems to be a greater push from companies to look at service partners who can offer near-shore (neighboring country with similar language and cultural background) and on-shore (outsourced within the same country) options as well.

While there are many reasons for the shift towards these options, one of the main reasons is the current economic slowdown which has given rise to a more ‘politically sensitive’ business environment. Companies are making a conscious effort to be seen as preserving jobs within the same country, thus, helping to reduce unemployment.

Like all business models, BPO continues to evolve and companies are now viewing it as more of an ‘operational advantage’. Companies are looking at partnering with service partners who can not only give them the cost benefits but also give them an edge over their competitors. By creating the right partnerships, companies hope to build the correct model to have a strategic impact on the way they operate and deliver service.

Current Drivers for Outsourcing

While cost continues to be the number one driver for outsourcing, there is increasingly a shift towards driving more benefit out of the outsourcing model. Companies are looking at more strategic factors like, globalizing businesses more effectively, re-engineering business processes and accessing expertise etc.

The above study highlights the top drivers behind companies looking to outsource.

Increased focus on efficiency and cost reduction

Increased emphasis on quality and customer needs

Increased importance on automation and optimization

Finding service partners with flexible pricing models

Global options – enabling a mix of near-shore, on-shore and off shore locations

Companies are looking at technology to increase their business benefits. As the world slowly tries to grapple with the current slowdown in the economy, cost reductions and process transformations become a key market differentiator. One can see a significant shift towards seeking service partners who can conceptualize and proactively introduce newer systems and platforms.

Platform based BPO is a step in that direction whereas service partners like Tech Mahindra are utilizing their synergy between BPO and IT to create customized platforms. This ability to integrate technology with business process knowledge has given a new dimension to BPO, and through that, service partners can now seek contracts at a much larger and more strategic level.

Platform based BPO offers process standardization, improved quality through automation, economy of scale and more importantly, bestows the complete responsibility of the


platform on the service partner who will provide platform-maintenance, upgrades and give the flexibility to modify and reengineer the platform according to the needs of the company (client).

With the growing competition within the platform based BPO market, all service partners will need to look at their innovation models and also start looking at complimenting these platforms with better and more innovative pricing strategies. They will need to start looking inwards and put more business practices in place to improve their own cost structure. Simultaneously, service partners will also need to start seeking new and improved technologies to be able to continue providing better and more efficient service offerings.

Cloud computing has surely given a new dimension to the complete outsourcing arena (SaaS, PaaS and IaaS) and service partners may need to assess if the cloud can become an integral part of their service offering. They will also need to assess whether BPO can reinvent itself by becoming part of the cloud. Service providers with BPO capabilities will find it imperative to embrace this change to ensure that they continue to operate on better operating margins and continue to pass on the benefits while creating opportunities for cost reduction within their own models.


Cloud Computing Defined

Gartner research, as shown in figure 4, in its most recent Top 10 Technology study examined the maturity of technologies and offers IT Executives a perspective on the trends and technologies that will have a significant impact in the coming year.

Figure 4: Gartner press release Oct 14, 2008 entitled “Gartner Identifies the Top 10 Strategic Technologies for 2009” and Gartner press release Oct 20, 2009 entitled “Gartner Identifies the Top 10 Strategic Technologies for 2010”.

As seen in the figure above, cloud computing is expected to be the number one technology which will be explored and leveraged for strategic advantage by various companies.

Cloud computing has been defined as: A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (This definition is from the draft of the NIST Working Definition of Cloud Computing published by the U.S. Government's National Institute of Standards and Technology) In simple terms, cloud computing is the use of the Internet for the tasks performed on the computer. The ‘Cloud’ represents the internet. Cloud computing is related to several technologies and the convergence of various technologies has emerged to be called cloud computing. The simplest thing that a computer does is to store and retrieve information. We can store family photographs, favorite songs, or even save movies on it. This is also the most basic service offered by cloud computing.


The cloud computing services market will generate $45.5 billion in revenue by 2015, says a report published by Telecom Trends International.

Figure 10: Cloud Computing Service revenue forecast – Telecom Trends Int, Inc

We have been exposed to cloud computing for a while now. Ever since the internet was introduced into the mainstream economy, cloud computing was in existence and was taking shape. Hotmail, Gmail or various other mail services are a perfect example of cloud computing.

Delivery Models

Figure 5: Cloud Computing Ecosystem

The NIST definition of cloud computing also defines delivery models and deployment models: Software as a Service (SaaS): The consumer uses an application, but does not control

the operating system, hardware or network infrastructure on which it's running.

Platform as a Service (PaaS): The consumer uses a hosting environment for their applications. The consumer controls the applications that run in the environment (and

SaaS

PaaS

IaaS


possibly has some control over the hosting environment), but does not control the operating system, hardware or network infrastructure on which they are running. The platform is typically an application framework.

Infrastructure as a Service (IaaS): The consumer uses "fundamental computing resources" such as processing power, storage, networking components or middleware. The consumer can control the operating system, storage, deployed applications and possibly networking components such as firewalls and load balancers, but not the cloud infrastructure beneath them.

While there is an implied hierarchy of delivery of services in the cloud as shown in the Figure 5, it is not imperative that this model will be followed by all. A few Customers will not seek IaaS but will look to utilize software in the cloud (Google docs).

Deployment models:

The below figure illustrates the different kinds of deployment models.

Figure 6: Cloud Deployment models – Source Frost & Sullivan

Public Cloud: In simple terms, public cloud services are characterized as being available

to clients from a third party service provider via the Internet. The term “public” does not always mean free, even though it can be free or fairly inexpensive to use. A public cloud does not mean that a user’s data is publically visible; public cloud vendors typically provide an access controlled mechanism for their users. Public clouds provide an elastic and cost effective means to deploy solutions.


Private Cloud: A private cloud offers many of the benefits of a public cloud computing environment, such as being elastic and service based. The difference between a private cloud and a public cloud is that in a private cloud-based service, data and processes are managed within the organization without the restrictions of network bandwidth, security exposures and legal requirements that using public cloud services might entail. In addition, private cloud services offer the provider and the user greater control of the cloud infrastructure, improving security and resiliency because user access and the networks used are restricted and designated.

Hybrid Cloud: A hybrid cloud is a combination of a public and private cloud that interoperates. In this model users typically outsource non-business critical information and processing to the public cloud, while keeping business-critical services and data in their control.

Community Cloud: The cloud infrastructure is shared by several organizations and it supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise.

Benefits of Cloud Computing The very basic benefit of the cloud is the fact that computing will be done online. Access to information and applications will be via a browser. Applications and software will be installed on a server accessed through the internet. This will enable greater reach and access to information at any time. Below are few of the benefits as described in Cindy Waxer’s article on WebHostingunleashed.com titled ‘The Benefits of Cloud Computing’.

Scalability: IT departments that anticipate an enormous uptick in user load need not scramble to secure additional hardware and software with cloud computing. Instead, an organization can add and subtract capacity as its network load dictates. Better yet, because cloud-computing follows a utility model in which service costs are based on consumption, companies pay for only what they use.

Easy Implementation: Without the need to purchase hardware, software licenses or implementation services, a company can get its cloud-computing arrangement off the ground in record time — and for a fraction of the cost of an on-premise solution.

Skilled Practitioners: When a particular technology becomes popular, it’s not uncommon for a whole slew of vendors to jump on the bandwagon. In the case of cloud computing, however, vendors have typically been reputable enough to offer customers reliable service and large enough to deliver huge datacenters with endless amounts of storage and computing capacity. These vendors include industry stalwarts such as Microsoft, Google, IBM, Yahoo! Inc. and Amazon.com Inc.

Freeing Up Internal Resources: By placing storage and server needs in the hands of an outsourcer, a company essentially shifts the burden placed on its in-house IT team to a


third-party provider. The result: In-house IT departments can focus on business-critical tasks without having to incur additional costs in man power and training.

Quality of Service: Network outages can send an IT department scrambling for answers. But in the case of cloud computing, it’s up to a company’s selected Service Partner to offer 24x7 customer support and an immediate response to emergency situations. That’s not to suggest that outages don’t occur. In February 2008, Amazon.com had their S3 cloud-computing service experience a brief outage that affected a number of companies. Fortunately, service was restored within three hours.

Cloud Computing Concerns

One of the main concerns surrounding cloud computing is that of privacy and security when dealing with transactions over the internet. Security concerns are highlighted with the knowledge of having sensitive company information hosted on someone else’s data-centers. Other concerns are of more abstract nature such as ownership of data and if the host can keep the information even after a contract ends? How good will the interoperability of information be, post migration into the cloud? Can a multiple vendor strategy still be used? A few tips to counter the privacy tips are given by Robert Gellman and Pam Dixon in ‘Cloud Computing Privacy tips’ – Feb. 2009- World Privacy forum

Most of the above concerns are not new and exist even in the current outsourcing models. With current outsourcing deals, there are no easy answers and all of them are going to depend upon the organization and how it works today and where the vision is leading it. In spite of the many concerns that cloud computing can raise, it is still a viable alternative rather than investing into a completely overhauled network.

So where does BPO fit into the cloud? And how does cloud help BPO providers deal with the challenges that they face in the current economy. Forester research has just published a new report entitled "The Evolution of Cloud Computing Markets". The research recaps many of the cloud computing market observations from the last two years and categorizes the business models in a consistent taxonomy. Some portion of the current BPO market might transform into dynamic BPO services or even Business Process as a Service (BPaaS).

Why BPO in the Cloud is Important

Various engagements are now moving towards a combination of both IT and BPO. Platform BPO is a direct result of the synergy where both verticals have and will need to continuously complement each other. Co-existing teams will need to be made up of business process expertise along with IT development and architecture.

One of the main focuses of various service partners has been to try and create an extension of their existing business engagements with companies to further enhance the relationship through prescribing to an end to end service model which includes BPO services.

Cloud computing presents a unique opportunity whereby end to end services can be provided within horizontals as well as verticals across all lines of service over the internet. Business process services can be categorized across all three cloud delivery models thus enabling cloud services to be more standardized and process centric. Inexpensive labor required for the BPO services within the cloud will only add to the advantages of cloud computing.

Companies looking to take advantage of cloud computing in its current form will need to address important questions like, whether the applications and platforms in the cloud constitute the vertical knowledge needed by the company and if the process centric approach is enabled within the cloud? Companies will need service partners who possess the business knowledge and can contribute through process led services which are an integral part of every company’s operational strategy.

While taking a closer look at the current cloud environment, it is clear that most of the cloud providers may not possibly know about the internal processes of a particular organization or a particular vertical. While business process within an organization is implemented based on primary tasks related to the particular company, what varies is the task-specific business information which addresses not only the industry regulation requirements but also company specific strategies and end customer centric processes.

Service partners with BPO capabilities will have to play a crucial role in the development and success of cloud computing. Cloud in its current form generalizes business functions instead of basing it on process centric information and steps. Simply putting business knowledge on top of scalable infrastructure is not the answer to high quality needs. For example, a telecom organization can utilize Cloud providers for billing processing but not align billing based on their own offers and discounts that can only be done through process centric platform management. This is especially true in markets where quad play (TV, internet, wireless and wire line) strategies are extremely fluid and where different marketing tools are extensively being used to increase the customer base. What is required is to integrate the business process knowledge with services needed to support those applications.

So what do companies looking to outsource want? They essentially are still looking at service partners who can provide them high quality work at a cost effective rate. To add to the advantages of less expensive labor, an end to end service model will provide


companies the ability to tap into SaaS solutions which provide the one-to-many process templates that reinforce BPO.

Figure 8: Majority of enterprises are considering blended IT-BPO engagements | Source: Horses for Sources Research, 2010

As seen in the earlier figure, two-thirds of companies now evaluate ITO/BPO solutions as a bundled option. This clearly shows that there is a need for BPO to be integrated within the cloud. Since business process-oriented cloud is a sub-set of company polices and business process models, cloud has to preserve and mirror these and be able to tap into the rules based business functionalities which would affect the end customer.

The combination of applications, infrastructure and business process creates a compelling and often envious solution base. The fact that most of the deals today are still based on vertical knowledge only highlights the need for BPO to be included and integrated into a ‘cloud sourcing’ model. Solutions catered to verticals like telecom, healthcare etc. need solutions which not only provide the advantages that cloud can offer but also leverage on the required understanding of the business processes which BPO along with Business Process Management (BPM) specialize in .

With the economic slowdown, finding the right service partner is often the key to a successful delivery. There is a constant need to take the service to the next level and Cloud as a Service (CaaS) will not be fully utilized if companies look at only leveraging infrastructure from providers/ partners like Amazon, Google or Microsoft. Companies need to look at service partners who can support, consult and provide business process advantages across all three delivery models especially in terms of support services or by an introduction of a platform to compliment the support services. For example, order fallout management which continues to be a main focus within telecom industry- companies are looking at service partner who can bring smart process led applications which can give them a real competitive advantage- reduce the cycle time, reduce touch points, target high fallout areas while combining self-service etc.


Service partners will have to be careful about their cloud strategies. Integrated providers who are willing to create a niche for themselves may want a flexible model in which they can offer –

Cloud hosting services (hosting information on its own cloud deployment network and giving companies the option of choosing from them - private, public or hybrid) to small to medium business that are looking to offload their CAPEX and are in no state to invest in infrastructure.

Giving BPO led support services within clouds owned by other players like Microsoft, Google and Amazon.

Providing migration, maintenance and business support services to companies who are building its own private cloud.

The above model can be interlaced depending on the type of services needed by the client (company), its geographic location, size and business strategies.

How Cloud can help Service Partners

With the constant pressure from the companies for higher quality at inexpensive rates, service partners with integrated IT-BPO service capabilities will need to continuously push the levels of innovation and cost elimination within their own processes and models. Providing standardized business processes along with an IT framework in the cloud provides service partners a unique opportunity to utilize cloud advantages to create a more flexible, innovative and cost efficient model.

With the immergence of BPOS (Microsoft) and Google docs (SaaS), utilizing a well known model of pay per use will need to be utilized by service partners quite significantly.

CAPEX to OPEX

Cloud gives the opportunity for service partners now to move from a CAPEX model to OPEX model for their BPO services as well. With the immergence of BPOS (Microsoft) and Google docs (SaaS), utilizing pay per demand, service partners can reduce the upfront costs of buying licenses which can later be rendered unusable in times of down turns. Instead, cloud enables them to have on-demand pricing which reduces investments. If capital is considered as a cost, cloud improves revenues and the capital can be utilized in a more efficient manner, enabling improved margins or giving benefits back to the customer.

Such a model enables service partners with BPO capabilities to take more risks. Initiating or inducting new technologies or platforms to win new business will be more accessible, seamless and more importantly, it will reduce the risk of investing in them even if the business is not won. Cloud is going to change the way financial capital is put behind new initiatives and the reduction of capital expense will result in–

Faster Return On Investment – return on investments which would normally take up to one or two years will be much faster as most of the expenses now will move as an operational expense


Reduction of Risk – making investments and the failure of risk will no longer be road block for Service Partners.

Shift from CAPEX to OPEX gives service partners an opportunity to try and reduce operations costs by innovation and better operations management there by resulting in improved margins.

Cloud – Impact on Technology Costs

With the advent of cloud computing, access to information and platforms, as well as applications, will only need a secured internet connection. This eliminates large amount of technology setup costs (upfront cost) for building call centers or back office centers. Here the initial CAPEX as well as the OPEX will see a significant reduction thus enabling further cost saving for both service partners and their clients (companies).

Being in the Cloud 24x7

Outsourcing itself will mirror a pure play call centre environment where real time usage of applications and software become more relevant.

Taking the call centre environment a step further, service partners can utilize the web service model ’cloud’- to deliver service from any location at any time, hence enabling physical relocation and expansion to be a seamless experience. With the push towards ‘on-shore’ operations taking more significance, the cloud will enable service partners to take advantage of ‘work from home’ concept thus reducing infrastructure cost of set up, expansion and maintenance.

Utilizing applications and software on pay per use (on demand) enables the concept of using application utilization up to 3 times (ideal scenario - 3 shifts of 8 hrs each). Workforce and capacity management in fact will become more OPEX conscious there by giving service partners another avenue of cost realization and reduction.

Cloud – Replacing the Traditional Disaster Recovery Plan

BPO comes with a few risks and one of them has always been- what happens if there is a disaster at the service partners’ site? Customers have insisted on a disaster recovery plan which further burdens service partners with infrastructure, connectivity and human resource costs. Physical bodies need to be present in multiple locations (sites) to be able to handle significant load in an event of a disaster at the primary site. Accessibility to data, applications and information from any place at any time, one of the key advantages of cloud can quite literally render such disaster recovery plans insignificant and further help reduce costs (OPEX and CAPEX) thus enabling service partners to give further value. Cloud itself having a contingency plan as a measure of disaster recovery is a perquisite for cloud computing to succeed and hence it is assumed that cloud / internet connectivity is a constant.


Conclusion

In conclusion, service partners who manage to fully integrate their cloud offerings with in-depth business vertical knowledge (business processes layer) and give the end to end solution will surely have a significant advantage over providers with BPO or IT only services. Service providers will need to utilize cloud computing advantages to their own business models to redefine themselves and remain competitive in the coming decade.

Integration of BPO within cloud computing will surely become the norm as adoption of cloud computing increases. Integration of business and service oriented technology platforms will need to have the flexibility of supporting the end customer through business process services and will be invaluable.

Like any new technology, cloud has its own risks but being ready to convert a risk into an opportunity will need Integrated (IT+BPO) service partners to be within the cloud. It is only when one buys a lottery ticket, does one have an opportunity to win something. BPO in the cloud will not only bring process centric knowledge and flexibility but also a wide variety of support services which are needed and continue to impact the end customer.
