• Measuring the implementation of objectives, primarily through quantitative indicators (see below) 
• Measuring the impact of this implementation, (i.e. outcomes) which requires a more qualitative analysis, often through evaluation studies which interpret the quantitative data in the context of the stated Vision, Mission and Aims.

For some straightforward short timescale objectives both types of measurement could be reported annually. For longer term objectives or initiatives the qualitative performance measuring and reporting intervals may have to be longer, perhaps as part of the 5 yearly World Heritage Site Management Plan review. The process for collecting qualitative data could be based on a system of annual returns, where the World Heritage Site Office circulate pre-agreed forms to the Partners and key agencies, which are returned and then analysed by the World Heritage Site Office and published in an annual report to the Partnership.

In relation to visitors and users of the World Heritage Site, the Marketing Strategy will establish current baseline performance information which can then be used to set targets and compare subsequent performance figures against. District councils, Government Office for South West and the Objective One Office have considerable experience in developing local indicators which the World Heritage Site Office will need to examine.

The State of the Historic Environment Report (SHER) 2003 produced by English Heritage provides a list of suggested indicators which will be subject to wider consultation in 2004. The World Heritage Site Office will follow the consultation process carefully and look to utilise common indicators where possible. Suggested quantitative indicators for the nominated Site are:

• Users - number of school visits to mining attractions, mineral tramway visitors, website hits, press enquiries, proportion of minority groups as users.
• Enhancement – number of mine sites/buildings/streetscapes conserved, new webpages created, new educational material produced.
• Economics - public funds invested in relation to private finance invested, income from tourism as % of Gross Domestic Product, employment generated and sustained.
• Protection - number of designations (Scheduled Monuments, Conservation Areas, Conservation Area Appraisals, Article 4s) created, number of Development Plans and other strategic document (local transport plan, community strategy) with World Heritage Site policies.
• Condition - number of buildings/monuments at risk, number of conservation area consents/ enforcement cases, number of planning applications and other development proposals receiving World Heritage Site Office advice.
• Skills - number of qualified staff involved in the World Heritage Site, number of training opportunities provided.

Administrative arrangements

The current World Heritage Site Bid team report to both the Officer Working Group and the World Heritage Site Bid Partnership, with day to day line management provided through Cornwall County Council’s Environment and Heritage Service. Reporting arrangements and timescales during compilation of the World Heritage Site Bid were defined in the Project Design documents produced as part of the application for Objective One grant funding.

Implementation of the Management Plan will necessitate a review of current administrative arrangements. It is envisaged that an Executive Management Group will be required, which includes those organisations with management responsibility for substantial proportions of the nominated Site, but is of a size that can exercise executive functions. Members of this group would be responsible for maintaining management information required to assess achievement of the key performance indicators and providing this for the World Heritage Site Co-ordinator. Monitoring progress could be through a programme of regular meetings, with a more detailed evaluation and analysis of outcomes in the form of an annual report of achievement provided for the wider World Heritage Site Bid Partnership (or its successor body).

Results of Previous Reporting Exercises
Reports on the state of conservation and previous records referred to under Form and Date of Most Recent Records of Property are held with several public bodies (including Cornwall Council, Devon County Council, English Heritage). Addresses for these public bodies are provided in Documentation.
