Through-life Management involves the life-cycle management of the products, services and activities required to deliver a fully integrated capability to the customer, while reducing the cost of ownership for the customer.

The installation stage occurs in In-Service Operations. At this stage, the machinery is shipped and installed on the buyer's premises and check to ensure that it is working to the standards set out in the design specification.

Lean design is about maximising the value that a customer receives and at the same time minimis-ing waste in delivering that value.
For an organisation to be 'lean' it must have had all non-essential resources removed (ie. anything that does not add value, see below). This is efficient and cost effective, in that the value/supply chain can theoretically do exactly what is needed of it and no more, but requires sound forecasting and planning of demand and supply. It is most suitable for industries with stable product specifications, long lead times and few impulse purchases.
Organisations which are 'agile' react as quickly as is practicable to provide a cost effective response to customer demand. This is based on flexibility in design, supply, production and distribution. It is most appropriate for products such as fast fashion and foodstuffs which must be on display and available when wanted by the customer.

Risk management has become incredibly complex, especially for capital purchase which requires through-life contract. Any source of risks should be identified and closely managed from the specification stage.
There should be sufficient information in the specification to minimise risks later in the through-life contract. Here is something to consider:
- Make sure the parties to the contract are clearly identified. This is particularly important if a prime contractor is being used. Allow them to subcontract elements of the specification.
- Clearly identify any testing and quality assurance procedures and who will perform them.
- Document every important aspect of the specification including a project plan
- Include a reasonable limitation of liability clause in the contract and reference it in the specifica-tion
- Identify any guarantees that are needed
- Be clear on what insurance will and will not cover
- Make sure there is clear audit trail of any changes to the specification together with approvals LO 3, AC 3.2

In this question, you have to calculate price variance and quantity variance.
Last month, 1 tonne of steel costed $216. This month, the price decreases to $181.1. Price variance = (P1 - P2)
*Q2 = ($216-$181.1)*11 = $383.9
Quantity variance = (Q1-Q2)*P1 = -$216
Price variance is greater than quantity variance, therefore, price variance is the main cost driver.
