Business Development Project Manager

Welwyn Garden City, Hertfordshire, Uk

From 2003-2006, I was Business Development Manager. I played an instrumental role in a new joint venture that was failing, due to a lack of agreed vision and business plan, plus large cultural differences. However, I made an immediate impact as I led Tesco and the Nutri Centre Board to agree new vision, goals and ways of working; plus a strategy for growth focused on the successful new health and wellbeing web and store formats. I launched a new store model that step changed sales and profit over 2 yearsFrom 2001 to 2003, I took on the role of Project Manager, where I had 3 notable successes. I developed a non-food store model that would transform performance in superstores. I analysed sales performance and designed a flexible ranging, staffing, training and warehouse model that always met the needs of local customers and delivered a return on capital investment. Subsequently this was rolled out to all superstores as part of the refit programme, making a significant difference to the Tesco P&L. On another project I led data analysis and business process review to root cause and design supply chain solutions, influencing the Board to adopt the recommendations and significantly reduce shrink that had got out of control. On another project, I redefined the role of the resourcing team to recruit staff for key change projects and new business ventures in the UK & overseas.It was during this phase of my career that I developed my passion for leading change projects and programmes and was privileged to witness how Tesco planned, resourced and implemented strategic change programmes to improve service, reduce costs and engage their people.

This led to my appointment as Category Manager in Corporate Purchasing where I led the design and implementation of a value chain approach to procurement that secured up to 40% reduction in costs from reliable sources. I was regularly seconded to new initiatives e.g. training in core skills, work simplification
