http://evaintheuk.org/eva-19-success/ EVA19, the established Earned Value conference, took place again this year towards the end of May. The venue again was the magnificent Armourer’s Hall; steeped in tradition and just a stone’s throw from St. Paul’s Cathedral. This year the plan was to explore the ‘ABC’ of project management – Agile, Benefits and Complex.

The backdrop proved to be as poignant as ever, as Steven Carver regaled the audience with the story of Alfred the Great, using real-life actors and Jonathan Crone provided Lessons from WW1, and the heroic battle of Vimy Ridge.

The military theme culminated with Lt. Colonel Tom de La Rue explaining what Leadership means in the context of an Apache Helicopter squadron on active service, and as the commanding officer of Prince Harry, in Afghanistan.

The two days, which included a banquet in the impressive livery dining hall, were engaging and intimate with the emphasis on personal development and learning together. The speakers were practitioners and professionals of the highest calibre, with many having taken time out from their day-jobs as managers and directors of mega-projects and programmes, to share their considerable knowledge and experience.

Steve says “The emergent themes from the conference this year were the importance of people and culture. Organisations need to move beyond slavishly following process and create an environment where project managers can really thrive. It is vital in any project that stakeholders are properly engaged which underlines the fundamental need for project professionals to Listen, Learn and Lead.”

Steve’s events have a reputation for being innovative and edgy – and this year was no exception. Peter Taylor, the project manager who smiles, entertained the audience with anecdotes and stories, including a personal favourite about a genie, a project manager and the task of building a bridge over the Atlantic. Jack Pinter was masterful in teaching members of the audience how to write the project management blues, which he went on to perform with his band throughout the day.

The feedback from the audience was extremely positive including this example. “The strength of the conference for me is the thread between the sessions that allows me to join the dots to meet my needs. I can create my own landscape from the wealth of knowledge and experience shared [maybe not the one I was expecting] and, perhaps most importantly, gets that mental recharge for the next set of challenges. Roll on next year!”

Steve says “The ‘eVa in the UK’ series has a reputation for giving something back to the profession. One way it does this is by creating a rich learning legacy. With the help of its many speakers, supporters and generous sponsors, most notably PM Channel, it has been able to accrue an impressive archive of presentations, video programmes and podcasts which can all be accessed from the archive section of this web site”

  • Thames Tideway TunnelThames Tideway Tunnel Delivery model
  • Delivery model Thames Water has been working with the Government and Ofwat to consider a range of models to ensure a value for money solution Preferred route is Regulated Infrastructure Provider (IP) under the Flood and Water Management Act 2010 IP shall be formed through a competitive process and will build, manage and maintain the tunnel. TWUL will operate it IP shall be regulated by Ofwat One third of investment will be from Thames Water, two thirds will be from the IP Value for money (Defra consultation of December 2013) Delivery of the Project through an IP would lead to better value for money for customers than if the Project were delivered through Thames Water. This is because the Project’s higher than usual risks would affect the entirety of Thames Water’s business, and so would increase the cost of financing for all of Thames Water’s investments. 28
