Instead of eight category heads reporting to him, Harrison has reorganised the department into a pyramid structure, with only three senior marketers now reporting to him. He has also split responsibility for Nestle's gifting and impulse brands.
Liam Newton, who headed KitKat, has taken the new role of brands marketing manager. As well as KitKat, he will oversee Aero, Double Cream, Rolo, Polo and Rowntree.
Harrison said Newton's promotion was due to his success running the KitKat business, which had record volume and turnover in 2001 and is still the UK's top confectionery brand.
The second senior marketer to report direct to Harrison is Jill Ross, who will work alongside Newton. Ross will continue to handle the gifting brands, including Quality Street, After Eight, All Stars, Matchmakers, Dairy Box and Black Magic.
"Because the gifting business is growing so fast, we decided to split the business between Liam and Jill," said Harrison.
Ross and Newton will be joined by Doug Walker, appointed to the new post of operational marketing manager. He will be responsible for delivering annual plans for the brands, based on the longer-term strategies set by Newton and Ross.
