This product-orientated thesis had a clear objective as to study planning an event in theory and to create amazing, flashy, perfectly executed and well-remembered event for the commissioner Blance Briel. Blanche Briel is planning to start a company once she feels like she has gained enough experience in the field. One of the objectives was as well to teach the commissioner the do’s and don'ts of the event planning industry. The plan was to give the commissioner better idea how to keep within budget, stay in track of time and how to execute well designed plan. The birthday party was organized by the author of this thesis, the commissioner and with the help of friends and family of the commissioner.

To the theory part of the thesis has been collected important information of planning a bigger private event like 30th birthday party with a bigger number of guests.

Planning an event is a vast and big project, which is very time consuming and needs great concentration from the organizer to be successful. Planning an event has several stages, and each previous completed step effects the next stage. The event organizer must be ready for quick changes as well as to be ready to make quick decisions.

The process of planning an event usually includes all together three stages, pre-, during- and post event phases. To create successful event all the stages must be planned and executed with great care. As the event gets bigger, the importance of delegating tasks and responsibility grows significantly, thus the project manager has a great responsibility to choose the right people for different tasks.

Product part has been executed from the knowledge and competence that has been collected into the theory part as well as from personal experiences. The methods used for the work were desk research and semi-structured qualitative research. The final product of this project is the event plan for the beautiful and fun birthday party called Thirty and fabulous which was kept on the 19th of May 2018 and the venue was located in Viikki, Helsinki. The objectives were partially reached. The budget was exceeded just a little circa 7 percent. The food would have finished if all the guests would have arrived and the event did not gather as many guests as the commissioner had wished and the commissioner did not feel like she learned anything new.
