You are the head of internal audit for Gotham City and have received an email from Councillor Joe Kerr. It appears that the Councillor has just returned from a public sector auditing conference where the terms 'value for money' and 'internal control' were referred to and he is keen to know more about these topics.
The email reads as follows:

From: Councillor Kerr

I've just returned from a conference on public sector auditing and admit that I found the whole thing rather confusing. I only went because I've just joined the Finance Committee and was hoping to get a greater understanding of the public accountability process.
Over coffee there appeared to be a large discussion about value for money. What exactly does this term mean? Could this technique be used to evaluate our waste collection service? At meetings of the Full Council we are always debating the cost of providing this service and before we make any decisions, it would be helpful to know how to assess the viability of the operation.
Although I've only been back in my office for two days, it has been brought to my attention that there have recently been a number of problems at the Transport Depot and many suspicions of irregularity. I seem to remember that some of my conference colleagues emphasized the importance of sound internal control and how this can play a key role in minimizing fraud and irregularity. If there is something inappropriate going on in the Depot, then what should we be looking for and how could we follow it up? I'm off to another conference next week, so an early response would be appreciated.
Cheers,

 Joe Kerr (Councillor)

Required:
Prepare a response for Councillor Kerr which addresses the following issues:
(a) (i) Explain what is meant by the term value for money and why it has more relevance to the public sector than the private sector.
(ii) Describe the factors which need to be considered in achieving value for money in the running of a waste collection service.
(b) What are the internal control procedures you would hope to find concerning:
(i) The purchase of vehicles?
(ii) The running costs of the fleet at the Transport Depot?
