The internal analysis includes a product audit. What this means is$,$

$$ a$.$ We examine the 'extended' or 'augmented' product, which is always fascinating

b$.$ We examine the products or services the business offers. Things like, sales level, prices, profitability or margins, dependencies between products

C$.$ We don't do the product audit, that's something that Finance should do

d$.$ We examine the products or services the business offers. Things like, what colour they are, how much they weigh, how many letters in their name.
