Xiaoyan,
I thought you’d like to know what has happened to your report about improving the website.
Last week I had a meeting with the designers. I gave them a copy of your report and I told them that we needed to have the website redesigned.
-- I’ve had the first page simplified.
-- I have asked them to make the icons large.
-- The colours are now different too.
-- There are more functions, as you suggested, so that customers will be able to transfer funds to an account in another bank.
I’m going to make a presentation about these changes at the Paris, conference and would like to talk to you about that. There are some things I can do myself, but I would like your help with some technical aspects. I must get some slides made too, and would like your opinion about them.
Have you got time for a coffee on either Wednesday or Thursday morning？
David

Cross training is training an employee to do a different part of the organization's work. Training worker A to do the task that worker B does and training B to do A’s task is cross training. Cross training is good for managers because it provides more flexibility in managing the workforce to get the job done. On the other hand, cross training has some benefits for the employees as well. It lets them learn new skills, makes them more valuable, keeps them stimulated and reduces worker boredom.
Cross training can be used in almost any position in almost any industry.I cross trained some of my design engineers to go on field installation trips and get first hand knowledge of how their designs worked, or didn’t work, in the field. Cashiers can be trained to stock shelves and stockers trained to cashier. This allows you to quickly open additional registers if the customer queue gets too long.
As you prepare cross training plans, you need to consider both the company benefits and the employee benefits. Carefullyselect the employees to be cross trained. Some people like to learn new things. Some are more comfortable sticking to what they know. Don’t decide which employees are ready for a change based on their age or performance.
