Sustained Competitive Advantage
What makes a firms resources »strategically valuable«? Which qualities does a resource need to have in order to ensure a sustainable competitive advantage? A conceptual framework dealing with this question is the one presented by J. B. Barney in an article for the Journal of Management in the early 90’s [1] and which some of you may already heard of by the VRIO acronym.
Before we have a look at what makes resources valuable let’s first define what is meant by a resource. The article defines a resource as:
[...] [including] all assets, capabilities, organizational processes, firm attributes, information, knowledge, etc. controlled by a firm that enable the firm to conceive of and implement strategies that improve its efficiency and effectiveness.
Evaluating the internal resources of a firm incorporates a very different view on strategy than the thought schools solely focussing on the external environment. While the latter treats the competing firms as black boxes with very similar content the former opens this boxes for further inspection and acknowledges the possibility for inner differentiation. Strengths and weaknesses as active weapons instead of reactive positioning between threats and opportunities.
What makes this approach especially valuable is the broadening of the availiable strategic options. The provision of additional internal knobs open to adjustment for gaining competitive advantage. The following drawing illustrates the different perspectives.
One of the articles main points is that not every resource creates sustainable advantage. In the authors words a firm is
[...] said to have a sustained competitive advantage when ist is implementing a value creating strategy not simultaneously being implemented by any current or potential competitors and when these other firms are unable to duplicate the benefits of this strategy.
Barney draws the conclusion that every resource resulting in sustainable advantage has to possess four attributes to qualify:
Value
Resources are said to be valuable if the improve the efficiency and effectiveness of a firm.
Rareness
In addition sustainable resources have to be rare. If resources can be easily obtained by competitors all gained advantages will be of short duration. Eventually the others will catch up restoring competitional equilibrium.
Imperfect Imitability
This attribute prevents competing firms to imitate the resources under question. The article mentions three reasons preventing easy imitation:
- History dependent: E. g. First mover advantages, brand names developed over a long timeframe, unique non recurring situations etc.
- Causal ambiguity: If nobody really knows why a firm achieves superior results it’s special traits can’t be recreated. Interesting aspect of this is that even the firm itself mustn’t know how it does the trick because if some managers knew how they did the trick competitors could lure them away and pay them to copy the resources.
- Social complexity: If superiority stems from special cultural aspects of a firm this quality is too complex to be recreated in a different company setting. Because social interactions in a firm can’t be directly managed this attribute is effectively preventing any duplication efforts.
Parting thoughts
One thing that came immediately into my mind when reading the article was the question if IT does qualify by these attributes. At first glance there is no chance: If something is easily replicatable it doesn’t qualify. Carr wins, case closed. But on further inspection there is still hope for us IT folks: Is it really so easy to just do SOA or install an ESB to catch up with other firms which did so successfully? Let’s give this a th… NO IT ISN’T. But why is this so? In my opinion it’s the factor of social complexity coming into play. If you can’t bring people together to effectively use a technology (or to use it at all) it will fail. And so it does. Again and again and again. What follows is that IT can be a competitive advantage as well as a sustainable one but only if you master the soft sides of it, too.
The second thing I had to think of was Lean Management. Once accepted as sort of Best Practice from the East, western management set out to copy the lean tools and procedures to gain back lost territory. Did it work? If they did so with the help of their eastern colleagues: sometimes. Just by observing and doing seemingly the exactly same things: almost never. Again social complexity is one of the factors at play here: Lean is more a holistic perspective on doing business than merely a set of tools which can be analyzed and used in isolation. This brings into play the second aspect: causal ambiguity. Because the frame of mind is totally different from the classical view on strategy we sometimes simply don’t have a clue why it works.
To me the whole framework is important because it counter-balances the very deliberate/deterministic positioning school of thought. Strategy is more than choosing a generic strategy based on analyis of external factors. It’s also about building inner strengths, core competencies if you will, to achieve sustainable results. With this perspective strategy gains back it’s creative sides which is all to easy lost in combat.
