The classification proposed in this paper includes a simultaneous parallel categorization that gives the growth of
literature during various time period:
1. Benchmarking: Research Papers
2. Benchmarking: Case Studies
3. Benchmarking: General Viewpoints
4. Benchmarking: Literature Reviews
One Pareto diagram of the number of publications in different categories is given in Figure 1.
All the publications in the categories, have been coded based on the chronological appearance of the article, for the
convenience of the readers. The first code in the form a number from 1 to 4, refers to the categories 1 to 4 illustrated
above. Coding has been done from 2000 onwards i.e. 3 years group for every category. Publications after 2000 have
been categorized on a time interval of three years.

Figure 1. Pareto diagram showing the number of publications with publications category.
The time periods are represented as “a”, “ b”, “c” and “d” from 2000 to 2012 into four groups i. e. shown in table 2
briefly.
Table 2. The coding pattern for classification based on time of publication
Time Period 2000-03 2003-06 2006-09 2009-12
Category a b c d
1 1a 1b 1c 1d
2 2a 2b 2c 2d
3 3a 3b 3c 3d
4 4a 4b 4c 4d
As an example the paper “ Benchmarking environmental performance : five leading steel mills in India” by M.
Rahul Amin & Sharmistha Banerjee 2010 is coded under 1- d . This means the publication was made during 2009
to 2012 (I.e. 2010) and it deals with category 1, “which is benchmarking research papers”. Similarly as belongs to
