Welcome to BPMSG – Dec 2012

Dear Friends, dear Visitors,

yesterday I realized 10000 visits on my website since April 2012, when I implemented the Piwik web statistics. Over the last couple of months the daily visitor frequency was actually increasing, doubling within the last 3 months. On my youtube channel http://www.youtube.com/bpmsg I am now slowly reaching 100,000 video views.

So first to all of you a big thank you, showing interest in the topics of bpmsg.com, and especially to those of you,  giving me feedback, as I can learn and progress from there. For me it also means to stay committed and keep the content interesting and updated.

The topic with the highest interest is AHP – the analytic hierarchy process, and many of you downloaded my AHP excel template. Actually, here I would really like even more feedback about your applications, just to get an idea, in what other areas my template is used. Some of them, as I received, are:

  • Asset management prioritisation
  • BPMSG AHP template as a teaching tool
  • Weights of textual elements that affect difficulty of a given text
  • Environmental quality
  • Threads to biodiversity
  • Green supply chain

In my last update of the template  I improved the accuracy of calculation  significantly, so please always use the latest version, and revisit the site from time to time, to get the latest update. Alternatively you might subscribe to the bpmsg newsfeed; the link is given in the footer of the page.

My latest topic “Diversity index as business KPI – the concept of diversity” seems also to gain some interest. My video on youtube  got in a short time more viewers than the previous video about operational and strategic business performance. For me it was intersting to apply the diversity concept in business performance, as I haven’t seen this before, and the mathematical concept, to measure diversity of species in a habitat (biodiversity), is quite well established . I am thinking to publish a second video, showing more practical applications of the diversity concept in a business context.

After starting my youtube channel in 2009, I gained more and more experience in making videos. You can  clearly see the difference, comparing one of my older videos with the latest ones. Now my camcorder – a Canon XA10 – is with me most of the time on my business trips or vacations. Therefore you also find some video travel impressions on this web site under the topic “others”. My last trip was to the Philippines showing the nice island of Bohol, as well as one of the world’s largest crater lakes on a lake on an island – Lake Taal.

Updated AHP Excel Template Version 11.12.12

AHP IconDue to feedback from several users, I revised the implementation of the power method for the calculation of the Eigenvector and Eigenvalue to improve the accuracy of my AHP excel template. The calculation sheet ‘8×8 in the workbook was completely reworked. My tests show a significant increase in accuracy. As an example see my updated post AHP template – numerical accuracy.

By default the number of iterations is now set to 12.  The check value in sheet ‘8×8 cell B33 shows the sum of all matrix elements solving the Eigenvalue equation (AI*λ) x = 0 with A the Decision matrix, λ = estimated principal Eigenvalue and x = estimated Eigenvector. The ideal check value is zero. With the example numbers given in the template the result is 5E-08.

Please let me know, if  you find any problems in the new version.

For the download of the latest version please go to the AHP template download page .

New AHP Excel template with multiple inputs

The AHP Excel template works under Windows OS and Excel version MS Excel 2013. The workbook consists of 20 input worksheets for pair-wise comparisons, a sheet for the consolidation of all judgments, a summary sheet to display the result, a sheet with reference tables (random index, limits for geometric consistency index GCI, judgment scales) and a sheet for solving the eigenvalue problem when using the eigenvector method (EVM). Latest version: 2018-09-15.

Alternative for complex AHP projects: AHP free online software.

Excel Template

  • Within the input worksheets (questionnaires) priorities are calculated using the row geometric mean method (RGMM).
  • Three consistency indices (the consistency ratio CR, the geometric consistency index GCI and overall dissonance Psi) are calculated. The level of consistency needed (α) is implemented as a variable input field in the summary sheet, and can be set between zero and one.
  • If CR exceeds α, the top 3 inconsistent pair-wise comparisons on the input sheets are highlighted, to allow the participants an adjustment of their judgments. The judgment resulting in lower inconsistency is proposed.
  • Final priorities are shown in a summary sheet; their calculation is based on the eigen vector method (EVM). For the solution of the eigenvalue problem the power method algorithm is applied with a fixed number of 20 iterations.
  • Different judgment scales are implemented.
  • Errors of the EVM and RGMM are show beside the calculated priorities.
  • Either individual participants, or an aggregation of individual judgments (AIJ) based on the weighted geometric mean of all participants’ judgments can be selected.

Limitations

  • The template does not include the hierarchy of the decision problem and the final aggregation of weights, i.e. it is only suitable for finding the weights in each category or sub-category. For the definition of a hierarchy and evaluation of alternatives see here.
  • Sensitivity analysis of the final result is not included.

BPMSG – One Year On-line

After being on-line with the website for 1 year, it’s time to change the entry page!

Here, on BPMSG.com you will find a couple of interesting articles related to business performance management, from a more practical than theoretical point of view.

Topics covered range from

A new topic was introduced just recently: “Value-driven leadership”. I started with a general article, and added a personality profiling tool (NEO-select). If interested, you might participate and send back the completed questionnaire to get a full report.

In the section other stuff  I post other interesting information, not fitting to the main topic of the site. For example a nice video of the olive-backed sunbird, a review of the Sennheiser Bluetooth Headset etc.

Conjoint analysis or stated preference analysis is used in many of the social sciences and applied sciences including marketing, product management, and operations research.

Here you find an simple example, how you can calculate part-worth utilities and relative preferences in Excel using multi-variable linear regression. (4 attributes, 2 level, fractional design)

PLEASE READ before DOWNLOAD
