ABF on our investment
“We continued our capital investment programme to upgrade and modernise the bakeries. The new bread line at our Stockport bakery came on stream in September 2012 and in April this year we opened a new bread line at Walthamstow creating one of the most advanced bakeries in the UK. At West Bromwich another new bread line completed commissioning during the autumn of 2013. This is the final stage of a five‐year investment journey at West Bromwich, which will leave the site as one of the biggest and most modern in the world”

Some thoughts to share……..
1. Don’t jump process especially when you are in a hurry
2. Develop realistic standards, systems and processes
3. Build a competent organisation
4. Pick the right contractors
5. Manage with rigor, its your neck on the block
6. Trust the numbers they seldom lie
7. Makes decisions when you have to, however difficult
8. Have the courage to lead
![Page 46: Introduction to Electrical Controls - IOSH](https://reader031.vdocument.in/reader031/viewer/2022012021/6169b55211a7b741a34a7b76/html5/thumbnails/46.jpg)
And Remember
It is not as easy as it looks
It will take longer than you think
If anything can go wrong it will
It will cost more than you estimated
