ACTA TECHNICA CORVINIENSIS – BULLETIN of ENGINEERINGprocess and also into output. These sensors arepart of the data – so called “indicators”, whichrecord the course of operations and allowcomparing results to standard output.The input data have to be gatheredcontinuously, so the demand and resourcesutilized in services could be observed.Operational algorithms have to be monitoredcontinuously because of obtaining ofinformation about exceptions, errors count anderrors in operation of the system. Outputinformation about amount and quality ofservices is needed to be harmonized withaccording processes. Except this, there isinevitable need of observation of externalenvironment of organization – data likedemographic characteristics of population,which the organization offers it services, servicesoffered by other organization – development ofcompetition, newest changes in ladder of values.These data indicators offer the leadingemployees a key that can help them in furtherstudy of situation and give them means tocorrect current state. (Khouri et al. 2009a)The development of a real self regulativeinformation system is not achievable aim. It ishowever possible to design a system withfollowing qualities:Information system of control has toproduce information, not data. It isnecessary to process data and analyzes themaccording to set plans and only then thedata can become information usable forleading employees.The gathered data have to be relevant to apurpose of their use. Data have to besensitive and must supply leading employeeswith differential and sensible comparisons.Information has to be without bias. It shouldnot be gathered and analyzed only for thepurpose of acknowledgment of propheciesof ambitious and egoistic leading employees.The system should be understandable andsynoptic. The employees doing decisionmaking should get all important element ofthe system.Information has to be prepared in time andbe to disposal before execution of neededdecisions and steps.Information should be oriented on activitiesand should be in the form of such synthesis,which will make decisions easier, itshouldn’t present only passive facts aboutpresent operations.It is important to have data unified andprecise; it should give indicators that can becompared in time internally with previousoutput and externally with experiences andresults of other institutions.Data folders should be gathered with regardto aims set before.Expected advantages that can be obtained byusing information should be higher thancosts needed to get a process it.

ACTA TECHNICA CORVINIENSIS – BULLETIN of ENGINEERINGcustomers. The customers (the chosenenterprise) demanded interconnection ofinformation by means of portal on the platformShare Point Portal Server. The new informationsystem should support obtaining of strategicaims of the enterprise, thus obtainingcompetitive advantage. Implementation ofactive planning was aimed to improve control ofeconomics and more efficient resources usage.The process of selection was very complicatedand it lasted three quarters of a year. Theenterprise has had a lot of experience withsuppliers and it has considered also in this casemany information systems. The main criteria ofselection was quality, scalability, know how inthe area of control of building manufacture andthe most user friendly interface. The othercriteria were complexity from the point of viewof demands on subsidiary processes andfunctioning of the enterprise. Support ofcreation, realization and optimization ofprojects and support of efficient cooperationwith a broad spectrum of external professionalpartners were also important factors.The course of implementation of theinformation systemAfter ending of the tender, before beginning ofimplementation, the enterprise had demanded aworkout of integration-implementation studythat mapped processes in the enterprise. Thisstudy was a important milestone beforeachieving agreement between enterprise aims ofthe customer and possibilities of the projectedinformation system. After negotiations andacceptation, the supplier offered a proposal ofsolution.The architecture of the system was proposedwith the aim to cover all enterprise processes –from search for customers, through bid andpreparation of contract, realization of building,handover of the building, to completion of theproject. The pillar of solution was the system forsupport of purchase, sales and finances. Thesystem had to be integrated with the system ofcontrol of building manufacture and tools ofCenkros software (the software of creation ofbuilding budgets), system for humans resourcesmanagement and salaries Human and with theenterprise portal offering subsidiary services, asevidence of contacts, management ofattendance, acceptance processes, etc. Thisconception would eliminate duplicity of data.All specialized demands were worked into theinformation system of the enterprise. Forexample, the module Finances demandeddeeper economic analyses, more detailedbudget planning, building specialties likemortgages, payment calendars, stoppers,workout of projects, observation of costs ofindividual projects, evaluation of projects,observation of commitments towards certaindate, or data acquisition for statistical needs.Every implementation of changes is facingmistrust at first. It was very important not toloose support from management of theenterprise during the course of the project.Usually the phases of analyzing and testing ofoutputs of the project are critical. In this process,it is inevitable to cooperate with the customer. Inthe chose enterprise, it was difficult for the keyemployees that had to dedicate main part oftheir work time to cooperation with theimplementer of the solution and they had to dotheir normal responsibilities.The course of the implementation wasmonitored on periodic seminars. The customerwanted to be sure, that capacities and financialmeans will be efficiently used with demandedresults, therefore it observed very precisely andconsulted the course and fulfillment of tasks. Inthis way, the project was lead to its final phase.Evaluation of assetsAfter implementation of the information system,the employees obtained a complex entry andquick overview of state of orders and projects.With information share, documents and forms ofShare Point Portal Server the duplicities werecancelled and teamwork was simplified.The solution fulfilled demands of the customeron mobility. The site managers that work onbuildings in terrain can connect to theenterprise’s portal by use of their notebooks. Inthis way they solve mainly exchange ofinformation that they need for their operation,like information about course of orders,economics and accounting documents,economics and accounting documents of theirprojects and similar ones.By use of online connection they can also reportabout the actual situation on the particularbuilding that shows a complex overview and2010/Fascicule 2/AprilJune /Tome III 89
