Formal Aspects
 
If you want to open knowledge media in a distributed environment for different partners which not necessarily belong to just one organization the issue of trust arises heavily. Trust is central for the sharing of knowledge in any case - but in that specific distributed scenario it becomes even more important.

The cultures of the organizations concerned have to be merged into a common safety culture, which builds the framework for the common project. Such a common safety culture has to be adapted to the security requirements of each of the concerned organizations as well as to the requirements of the distributed project work with its short project live cycles. To fulfill the requirements of the organizations the joint project safety culture has to correspond to the maximum number of the requirements.

In order to show the complexity of the parameters that have to be taken into account the problem can be formalized. Let n be the number of participating partner organizations and mi be the number of different organizational units of one of the partners. scmaxi is the maximal number of safety cultures within one organization and scmaxPEKM is the maximum of safety cultures that have to be joint to a single project safety culture.

scmaxi = mi (i, j, k, m, n N)

scmaxPEKM =

 

The amount of possible security issues of an organizational unit of one of the partners is represented by the vector req_ouj = (sec_issue1, sec_issue2, ...sec_issuet) where sec_issuek represents a security issue (e.g. availability or authentication). The minimum of requirements of one of the partners mreqi is the sum of the single requirements of its organizational units (assuming one partner will rather increase his security requirements he already has because of the necessity to exchange critical information and knowledge).

Finally, the minimum of security requirements of a PEKM can be expressed as the following combination of amounts:

These formulas indicate that the problem of finding a joint safety culture should not be underestimated. To build such a common safety culture there are various aspects, which have to be taken into account in the security management to enable the development of trust.

These aspects will be depened in a publication that appears in the 19 (8) November 2001 issue of the International Journal of Project Management as
