288 O.M. Magnussen, N.O.E. Olsson / International Journal of Project Management 24 (2006) 281–2887. Concluding discussionThe performed analyses show that the recommendedproject reserves on average are 9%. It is furthermoreobserved that no matter the scale of the project, the sizeof the reserves measured in per cent appear to be rathertypical, which is rather surprising, when it is kept in mindthat existing studies report overrun up to several hundredper cent.A discussion concerning the potential cost effect of thestochastic cost estimation and budgeting in public projectsis conducted. It is concluded that a final evaluation of thecost development must be done when the actual costs areavailable. Compliance to the approved budget rely to alarge extent on the management of the reserves and it isalso argued that it is questionable to judge projects notyet completed against past experience, which indicates thatprojects use at least their allocated budget, when adequatemeasures to reach realistic estimates at an early stage havebeen established.It is possible to conclude from the present study thatthere is a difference between the numbers proposed bythe project organisation and the revised estimates fromthe external consultant. This is based on the observationthat the revised estimates were higher than the initial estimatein 74% of the projects studied here. This is a ratherstrong indication since the estimates compared here areanswers to the same question. The study also shows thatthe differences were higher in the early stages of theRegime. The observed differences have decreased systematicallysince quality assurance was initiated in 2000. Somesuggestions based on empirical observations, the prevailingmethods and different views upon the analysed project arediscussed, but the most important result here is therevealed tendency in the existing material.The study further shows that for many projects in thesample, the parliamentary decision directly rely on the estimatesprovided by the external consultant. This supportsthe claim that the involved ministries, i.e., the project owners,benefit from the external assessment of the project, andactively use the provided information when preparing thedecision proposal for the Parliament.The observations here lead to the identification of importantissues that need to be addressed in further research. Arethe differences in the estimates systematic and statisticallysignificant? Are the differences observed when the schemewas new cost underestimation by the projects or overestimationby the consultants? Does the systematic decreaseimply a learning curve, or does it indicate an adjustmentto external demands? A closer look at the historical recordswill help to cast light on these issues.This paper is a report from the first analyses of cost estimatesin major public investment projects after the initiationof the Quality-at-entry Regime. Some experienceshave been gained, but there are many questions that needto be answered to get a picture of the effect of this initiativenot only in terms of reduction of cost overrun but alsolong-term feasibility and profitability of public projects.References[1] Berg P, Andersen K, Östby LE, Lilleby S, Styrvold S, Holand K, et al.Styring av statlige investeringer.
