The 2012 Summer Olympic development process began in 2005, following the successful London bid for the 2012 Summer Olympics, and ran until the games in 2012. While many of the plans were included in the bid portfolio, which gained the favour of the International Olympic Committee (IOC) over the four other bids on 6 July 2005, there were more details released and decisions made afterwards. The London Organising Committee of the Olympic Games and Paralympic Games (LOCOG) was created to oversee many of these developments, though such a large-scale event requires the co-operation of many other agencies. These organizations are sometimes integral parts of the London 2012 plans, while others are unrelated but can still have a great effect.

The day after the announcement saw one of the worst terrorist attacks in Britain, as London was struck by four bomb blasts. While the motivation was not linked specifically to the success of the bid it was to have an effect on the development and planning of the event.

Timelines Since the 2000 Summer Olympics in Sydney, Australia the IOC have developed a "master schedule" to ensure that the planning and development of the Games goes smoothly. Gilbert Felli, the IOC Executive Director for the Olympic Games, explained the master schedule as "a timeline of milestones that need to be met for the Games to be delivered on time."(25 November 2005). "London 2012: Orientation Seminar Concludes On Positive Note" at the Official Olympic Games site. Retrieved 25 November 2005.(25 November 2005). "London 2012 handed IOC checklist" at BBC News. Retrieved 25 November 2005. On 24 January 2006 LOCOG released full details of their plan, based partly on the IOC Master Schedule.

As of early 2005 60% of the venues and facilities were in place. The bid needed to detail the time plan for any further construction work that was required, and the London 2012 team came up with a schedule that would see all the facilities ready by 2011.
