2.1.2 ) Procurement in public sector in Greece and particularly in ministry of instruction

There are two sectors in where procurement dealing is take topographic point: public and private.

This undertaking emphasize in procurance in the populace sector in Greece and particularly in ministry of instruction. The procurance in the ministry of instruction in Greece is harmonizing the procurance in Greek populace sector. It is followed the same stairss and is managed by the same regulations.

Procurement in the public sector or public procurance is a term that is used about the contracts that became in composing between a provider and the assorted establishments in the public sector.A These minutess are about the bargain, the rental and the funding rental of goods. Besides, as procurance of the populace sector is thought the conventions of intrusting of execution of work of installing, care, conveyance and other plants.

Another definition harmonizing the Department of finance and forces of Northern Ireland refers that “Public procurance is the procedure of the acquisition, normally by agencies of a contractual agreement after public competition, of goods, services, plants and other supplies by the public service” .

Public procurance ( Carl Erik Moe et Al, 2006 ) is a sum of activities that guarantee goods or services for the public good utilizing public money. These activities are controlled by regulations in order to guarantee equal intervention for all parts. Public procurance through the buying procedure non merely satisfies its purpose but besides supports the private providers ( Jakob Edler, Luke Georghiou, 2007 ) .

Procurement in the populace sector are the purchases that are hold harmonizing concrete procedures by organisations of the public sector such as ministries, infirmaries, constabulary, firefighting. Besides, the purchases that are hold by sectors of the local authorities such as municipalities and communities and by authorities owned public utilities. These purchases are about goods and services that are thought necessary for the above organisations running.

Such as a buyer so the province in order to take the merchandise of its pick make research of market. In contrast to persons, the province does n’t travel to the providers in order to happen the most attractive monetary value but invites the providers to do their offer in a competition.
Public procurance is competed with the contracts that became in authorship. These contracts define the content and the footings of an understanding between an establishment and the provider.

Public sector in the chiefly corporate purchaser for the most national economic systems and the volume of the minutess between public disposals and the providers is immense. Consequently the European Commission ( 2002 ) , the purchases of goods, services and public plants by authoritiess and public public-service corporations are estimated at approximately 16 % of the Union ‘s GDP or a‚¬1500 billion in 2002. In Greece, the populace sector manages a large volume procurance that is more than 3500 billion in 2005, largely based handwritten processes. Besides public procurance is frequently considered as the engine of economic system as soak up the 15 % – 20 % ( general secretary of commercialism ) of entire national domestic merchandise. In many instances the province buys the sum or the major per centum of production of many companies.A

The procurance in the public sector policy should take in the creative activity of an equal, transparence and competitory without favoritisms environment. This environment would let the procurement stuff goods and services for the public establishments and will guarantee the most attractive value for these merchandises. As a consequence the populace beginnings will devour with cautiousness and will guarantee the public involvement. ) Basic rules of public procurance.

Harmonizing the general secretariat of commercialism in Greece that has the supervising the public procurance should guarantee three basic rules:

  • Principle of promotion. Each procurement dealing in the public sector should be printing in the interested parts through the national type and the official diary of the European Union. By this rule are excluded some procurement types such as procurances of low cost and is fixed by the jurisprudence.
  • Principle of transparence of procedures. The regulations, that are the public procurances are based, are specific and known from the really get downing. These regulations are in consequence in all the continuance and should be clear, expressed and apprehensible in all parts. The regulations for the public procurances are non allowed to alter after the proclamation of competition but merely in the instance that be accepted by any opportunity expostulations.
  • Principle of equal intervention. The regulations for the public procurances are non allowed to import policy of favoritisms about concrete companies.


For the accomplishment of the best advantage and the decrease of public disbursal in many instances is more utile to go aggregation of the demands of the markets of public organisations and intrusting of low cost procurance in external organic structures ( Darryl Coulthard, Tanya Castleman, 2001 ) . In the same clip is supported the healthy competition and the local market with crystalline procedures. The same though for high concentration of public procurance maps ( Marian Lemke Piotr, Nils Gorecki, 2008 ) to a organic structure is similar in many European provinces such as England, France, and Belgium etc. This centralised theoretical account of public procurance direction has many advantages:

  • Buying specialisation
  • Standardization and fusion of the procurance applications and their centralised direction.
  • The effectual procedure and direction the procurance services.

In the other manus there is the decentralised procurance theoretical account. In this theoretical account local disposals or individual decide the manner of procurance. They decide the clip, the mode and what will buy ( Nicola Dimitri et Al, 2006 ) . Harmonizing this theoretical account is required flexibleness in the public procurance procedures. Some advantages of the decentralized theoretical account are:

  • Simple communicating and cooperation between providers and public organic structure.
  • The velocity of dealing of procedures.
  • The effectual usage of local providers
  • The liberty of providers and public organisations.

The factors that affect the determination of chose between of centralised and decentralised theoretical account of procurement direction is the similarity of the stuffs or service, the measure of the procurance and geographic airing of the procedures. ) Procedures of public procurance

The procedures of public procurance contracts are divided in unfastened competition, close competition, procedure with dialogue and off-hand competition. ( General secretariat of commercialism in Greece ) .

Open competition or unfastened procedure

This procedure is safeguarded the highest possible attending by possible suppliers. It demands publish of the entire invitation and allows in each interested to do an offer. The establishment that makes the competition has non the duty to subject petition to each interested provider.

Close competition or stopping point procedure

In this procedure the establishment print the invitation show of interesting. It is a really general invitation. The interested parts put in application of their attending with an envelope of module in where depict the company ‘s profile. The entire invitation, with its elaborate features, could larn merely the interested parts that would choose with the elements of their module. In this instance they will be invited to subject complete offer with monetary value, proficient features etc. In the close invitation the establishment could put lowest and highest sum of providers that intend to ask for.

Procedure with dialogue

It ‘s a procedure in which each establishment chose the providers that they wish and negotiate the footings of the contract with one or more providers, with or without the publication of the invitation of the competition. In the dialogue it is demanded to ask for at least three providers. This procedure is followed merely in the instance where it is anticipated by the jurisprudence ( I? . 2286/95, I¬I?I?I?I? 2, IˆI±I? . 13 I?I±I? I .I” . 370/95, I¬I?I?I?I? 10 ) for illustration for pressing demands or for extra supplies by the same provider etc. Besides, some times this procedure is followed in the instance that a competition fails or in the instance that the achieved monetary values are thought unprofitable and there is pressing demand. In that instance the competition is continued with the procedure of the dialogue with the seting in new economic offers and new proficient offers. In such instance new offers could seting in from ab initio subjecting in the competition providers.

Off – manus competition or concise procedure

For the low budget supplies, that are defined by the jurisprudence and are out of the Community right, is applied the off-hand competition. This competition is allowed for supplies of low budget until a concrete order that is defined by a Ministerial Decision. In this sort of competition is non required publication and is keeping by a panel of three persons with the entry in composing offers. In the off- manus competition are invited at least three suppliers.A ) Legal frame in public procurance.

Consequently with the budget of the buying good, it is applied or the Grecian legal frame or the Grecian in relation with the European Union ‘s frame. More specific ( General secretariat of commercialism in Greece ) : A A

In the instance that the budget for the purchase of a good or service is lower than 200.000 euro, consequently the European ‘s Union Directive 36/93, is applied the national frame. The Grecian regulations that are about the procurance of public sector are I? . 2286/95 andIˆ.I? . 394/96.

If the budget for the purchase of the good is over the 200.000 euro the above regulations is applied in add-on with the European Union ‘s ( E.U ) legal frame.

O I I” 370/95 and I I” 105/2000 that integrate the national frame with the directives of E.U. 93/36 and 97/52.

O The Iˆ.I? . 57/2000that integrate the Grecian frame with the E.U. directives 93/38 and 98/4 and are about the procurance in the sector of public public-service corporations ( H2O supply ) , the energy and the transit.

O I? . 2522/97 and I? . 2854/00that guarantee the legal security of the rivals before the stage of the come ining into contract in connexion with the E.U directives 86/665 and 92/13.

2.2 E-procurement advantages

E-procurement benefits

There are many benefits by the application of e-procurement. The benefits could be measure and quality. These classs are equaled of import about the involved parts. Some of these benefits are the follow:

After that a major portion of the administrative disbursals cut down ( Rayport, Jaworski, 2001 ) .

The benefits of e-procurement

The benefits of e-procurement can be classified into

seven classs, which are briefly described below:

_ Decreasing monetary values: In traditional procurance systems,

buying from non-contracted sellers, known as

rebel purchasing, tends to diminish the bargaining

power of companies ( Boer et al. , 2002 ; Morris et al. ,

2000 ) . E-procurement can leverage dickering power by

set uping contracts with preferable providers, perchance

taking to discounted monetary values ( Venkatesan, 1992 ) .

Research indicates that possible decreases can be of

up to 20 % of the entire monetary value ( Morris et al. , 2000 ; Smart

_ Reduction of administrative disbursals: Administrations cover

with big Numberss of requisitions every twelvemonth, many of

which refer to moo value points. Traditionally these

procedures have been paper-based and have required

considerable manual labor and other costs such as

intra-company mail, phone charges, postage, run offing

and storage. E-procurement automates the full

requisition-to-payment procedure, increasing efficiency

and extinguishing unneeded disbursals. Furthermore,

the machine-controlled system can besides cut down those costs

associated with informations mistakes and inaccuracies inherent

to manual procedures ( Morris et al. , 2000 ; Rayport and

Jaworski, 2001 ; Smart and Harrison, 2003 ) .

_ Inventory decrease: Shorter rhythm times cut down carrying

demands, conveying with it a decrease in stock list

degrees and the cost associated with them. This decrease

in stock list can besides hold a strong positive impact on

hard currency flow, since the money tied up in stock list can

become available for other intents ( Morris et al. ,

2000 ) .

_ Shorter order rhythm times: The mechanization and work flow

installations of e-procurement applications allow administrations

to cut down the rhythm clip of purchases ( Morris et al. ,

2000 ) , bettering the overall flexibleness and reactivity

of the system.

_ Improved communicating and information flow: A recent

study looking at the benefits of e-procurement ( Croom,

2000 ) revealed that around 46 % of respondents believed

that e-procurement would assist better information

flow, and 41 % answered that e-procurement would take

to better internal and external communications.

provide consolidated inside informations of existent spend with each

provider and in each merchandise class, which are an

indispensable input for planning and control. Furthermore,

studies have shown that in companies involved in

e-procurement, buying staff pass less clip on

operative undertakings and more clip on strategic issues ( Flicker

and Holler, 2000 ) . Another study indicated that over

40 % of respondents believed that e-procurement would

lead to betterments in planning ( Croom, 2000 ) .

rates ( Fisher, 2000 ) .

2.2.4 ) E-procurementtypesinternational

The procurance in the populace and the private sector take topographic point in a assortment signifiers. This is a consequence of the usage of assorted engineerings, engineering platforms of assorted industries and different policies that are followed in the infinite in where the e-procurements take topographic point.

As a consequence the e-procurements international are supported by a sum of different methodological analysiss and systems. The basic value is that the operation of these systems is supported in the electronic exchange of informations through the cyberspace with the usage of engineerings such as CGI, ASP, Java, HTML, XML, Flash, Cobra, ERA etc. By the usage of these engineerings are searched providers, the procurance ‘s proclamation or the competition, send and credence of the indispensable elements, the pick of provider, and the procedures of blessing and signature of convention up to the completion of the process.A

E – Procurement is supported international by merchandises ( Commerce One, Ariba, Clarus, Broadvision, Openmarket, Intershop, Opensite, Trade Matrix, Web Sphere, , L @ dnscape, Icube, Exchange Market Place, Clarus, Cardonet, i2Technologies, Procurenet, Extricity, etc ) that are categorized to four large classs.

  • E-marketplaces
  • E-auctions
  • Rearward e-auctions

E-marketplace is a topographic point in the cyberspace that hosts one or more topographic points of purchasing and merchandising.

Today e-marketplaces are really popular. The crisp development of the cyberspace has impact to all the signifiers of the markets. In history, market places give the chance to clients to run into the providers at a certain topographic point, at a certain clip and to do purchasing or merchandising. E-marketplaces give the competitory advantage as is focused to the client ( Teck-Yong Eng, 2003 ) . An e-marketplace has a alone feature that is the meet of assorted buyers and providers together in a cardinal market place.

E-marketplaces can be categorized as follow:

Public e-marketplaces, is an unfastened market that is characterized by international attending and assorted types of interaction ( one to many, many to many etc ) .

Vertical e-marketplace, these market ‘s topographic points ( B2B ) are focused to a narrow scope by merchandises and services. Harmonizing Andrew H. Chen, Thomas F. Siems “Vertical markets are industry-specific. They focus on an single industry, such as steel, plastics, electronic constituents, or chemicals” .

E-AUCTIONS AND THEIR FORMS: An auction is the procedure in where providers provide an object and many purchasers rival by giving the best monetary value in order to get the object ( Jarrod Trevathan and Wayne Read, 2005 ) .

E-actions, it allows to multiple buyer to do competitory offers for merchandises from independent providers ( electronic auction ) via cyberspace. The e-auctions are based and follow the classical types of auction some of these are:

Dutch auction is the auction that is concluded by a marketer and many buyers ( Jarrod Trevathan and Wayne Read, 2005 ) . The director of the auction increasingly reduces the command until a buyer accepts. The first buyer that accepts the marketer ‘s offer is the victor of the auction. The Dutch auction has the hazard in the instance that the victor would n’t pay an sum equal with the command.

English auction is the auction in where there is one marketer that provides a merchandise for sale.A In the other manus there are many possible buyers that try to win the command. The buyer increasingly increases the monetary value in the offer in order to purchase the point ( Enrique Dans, 2001 ) .A A The buyer that would offer the highest monetary value for the point will be the victor.

  • Nipponese auction is the action in where there is one marketer and many purchasers. In this procedure the director of the action starts from a low monetary value and increasingly increases the monetary value and the possible purchasers should accept the offer in each degree in order to remain in the action. The victor is the purchaser that stays until the terminal offer ( Enrique Dans, 2001 ) .

In rearward e-auctions the buyers publish their demands for a specific good or service and the Sellerss make an offer in order to fulfill these demands. In other words, is similar to the traditional auction in contrary ( Daesik Hur et Al, 2004 ) . On the contrary with the competitory command contrary e-auctions do non bespeak written offer and the Sellerss give their offer in existent clip. This auction with the cyberspace ‘s usage brings the providers and the buyers together. The types of contrary e-auctions are the follows:

  • Reverse Dutch auction is the auction with a purchaser and many Sellerss. In this type the auction ‘s director increase the monetary value, get downing from a low monetary value, until a marketer to hold selling in this monetary value.
  • Reverse English auction is the auction with a purchaser and many Sellerss. The Sellerss cut down continually the point ‘s monetary value in order to sale it to the purchaser.

For each merchandise the marketer could add images, description, some more information, and monetary value etc. By the usage of e-catalogs the company provides information about the goods, colourful exposure, monetary values, maps etc ( Benjamin P. et Al, 2002 ) . Concisely, e-catalog is ‘’a aggregation of classified information ” ( Benjamin P. et Al, 2002 ) .

There are the follow types of e-catalogs:

Prequalification Systems

In the public procurance maps companies should turn out that satisfy specific economic, funding and proficient demands and besides their experience. Besides they should subject some needed paperss. The systems of prequalification could cut down the bureaucratism processes by the automatic entry and cheque of the needed paperss ( Ekambaram Palaneeswaran, Mohan Kumaraswam, 1999 ) . The paperss are checked one time in specific clip and legal frame and after that are available online for all public organic structures.
