Prisk spent his last day at the Michelmersh Brick and Tile Company, a brick manufacturer based in Hampshire.
Before that, he spent a day each at the following businesses:
Prisk summed up his experience yesterday: "My week with small businesses has been a fantastic experience and I can't wait to get to work with Michelmersh Brick and Tile Company. All of my work experience days have shown me the challenges faced by our small firms, and how the Government can help in creating the right environment for these businesses to flourish," he said.
In fact, the team at the Department for Business, Innovation and Skills (BIS) have also been on experience placements. According to the Department, 95% of the policy team have visited 123 different businesses over the last nine months.
"I have been hugely impressed by the dedication, ingenuity and enthusiasm of all the people I have worked with. We have some brilliant businesses in this country, which makes me extremely optimistic for the future of our economy," said Prisk, echoing sentiments expressed by David Cameron at the Conservative Spring Conference.
The government has repeatedly stated its belief that the small business market is important for generating growth in our economy. So great news that policy makers are visiting small businesses - but perhaps it would have been nice to know exactly what "challenges" Prisk came to understand on his visits. Then what he plans to do about them.
Before the election, Mr Prisk spoke with Smarta about his views and policies on small business and what he wanted to accomplish. Have a watch here and then decide whether he's on track or not.
