20:59Scalability in Operations Management
What is it?
It seems that this term, Scalability, is used by managers rarely. However you can meet it within MOOC courses, devoted to business and operations management or manufacturing systems. According to the analysis of publication (Putnik et al., 2013) Scalability within the manufacturing community has started to gain major attention since approximately the year 2000. G. Putnik and co-authors depicted dynamics of number of papers by the search terms ‘scalability AND manufacturing’ in world leading publishers’ collections such, as Elsevier, Springer, T&F, Wiley, Emerald, JSTOR, ACM, and IEEE. You may see that the number increased from about 200 to nearly 1600 over the period 2000-2012. Search results found for two queries <scalability AND operations management> and <scalability AND "operations management"> on ScienceDirect.com have showed rise in the quantity of scientific papers (Fig.1). Search terms included all sources by categories Business, Management and Accounting, Decision Sciences, Economics, Econometrics and Finance, Social Sciences.

Wikipedia contains an article that gives explanation of what Scalability means and where it is used. Here is a part of the article.
In brief, from economic point of view, Scalability is the ability of a system, network, process or even a firm to handle a growing amount of work, sales or demand in a capable and cost-effective manner.
Looking at definitions of scalability we may emphasize that scalability concerns manufacturing system, production system, logistics system, supply chain, etc. All these systems must have adjustable and adaptable structure that enables effective responses to demand changes and acheive lowest costs per function and total operating costs (Koren, 2006).
So, it's important to understand whether there is sufficient demand or not. If managers have had positive answer then it's time to check whether operations will work or not.
They wonder can the organization support this market in a cost effective way or cannot. Moreover, participating in a start-up, they decide what can be changed in the market, which had been targeted by the organization, or in operations so they can scale in a cost-effective manner.
These questions will be on the increase, therefore multiple functions within the organization will be taken into consideration. Given this Scalability as the feature operations management concerns a large range and variety of systems, which may be considered as operating system (operations).
Scalability of Operating System (Operations)
Let's refer to definition of Operating System to understand what it is.
Firstly we accept physical view of operating system that leads us to consider materials, machines and labour. But more broad economic view indicates that besides tangible resources the organization uses intangible ones in order to produce Value. If organization can convert produced value into cash, we can talk about these resources as Assets.
Assets help organization (firm) perform its activities to increase its value and to provide future benefits. Thus,
The flows through a network of activities that transform inputs into outputs represent Processes. The process view highlights how assets perform activities and add value, and how work flows in the organization.
Input, Transformation and Ouput are elements of other close concept such, as Production System. It's manufacturing subsystem that includes all function required to design, produce, dustribute, and service a manufactured product (Sarabjeet Singh, 2012).
It should be mentioned that Manufacture is one of the principal functions of an operating system or a production system. And it requires some physical transformation, or a change in form utility of resources. Output consists of goods, which differ from materials at input.
Transformation is also called by Processing, which includes the various functions that an operating system undertakes to convert inputs into ouputs, e.g. the raw materials into useful goods for customers, bed linen and towels, and rooms, and other things into hotel accomodation for travelers. Processing adds value to a product or a service and enables the organization to sell it in the market. (Mahadevan, 2010)
For Manufacturing System, as both a method of organizing production and collection of integrated equipment and human resources, whose function is to perform one or more Processing, Scalability could be seen as
What is next?
Besides functional aspects, considering a wider social concerns the Scalability should be adopted in tools for increasing organization value. Scalability captures new potential, capacity, and resource. Specifics of operating system's scalability make us to assume that it might be investigated with different meta-theoretical perspectives. These perspectives form critical framework for analysis that combines concepts, statement, mechanism and other elements from different theories.
