Kaupallisten ohjelmien lisenssihinnat voivat nousta korkeiksi ja olla hankinnan esteenä etenkin aloittelevilla yrityksillä. Tässä tutkimuk- sessa on kartoitettu kustannuksiltaan edullisia CAD, FEM ja CAM -ohjelmia, joita voisi käyttää yritystoiminnassa. CAD-ohjelmien puolella perinteisille 2D CAD-ohjelmille löytyy useita hyviä vaih- toehtoja. LibreCAD ja QCAD ovat helppokäyttöisiä ohjelmia perustason piirtämiseen. Solid Edge 2D Drafting on erittäin monipuolinen täysiverinen 2D CAD, joka perustuu parametriseen piirtämiseen. 3D CAD-ohjelmien puolella tarjonta on tasoltaan vaihtelevaa.

Tarkoituksena oli myös selvittää, mitä avoimen lähde­ koodin ohjelmia, ohjelmistoja ja käyttöjärjestelmiä voidaan käyttää kaupallis­ ten sijaan. Valitsin aiheen oman kiinnostukseni mukaan. Kiinnostuin avoimesta lähde­ koodista, kun aloin itse käyttämään Ubuntua käyttöjärjestelmänä. Huomasin kuinka kehittyneitä avoimen lähdekoodin ohjelmat, ohjelmistot ja käyttöjärjes­ telmät ovat, joten halusin tutkia kuinka paljon näitä hyödynnetään alallani. Tutkimusmenetelmäksi valitsin lomakehaastattelun, jonka tein verkkokyse­ lynä Limesurvey ­ohjelmalla. Limesurvey on avoimen lähdekoodin ohjelma, jolla voi tehdä kyselyitä ja analysoida niitä.
