Evaluations of plan implementation are typically conceived in terms of plan conformance (the degree to which outcomes align with planning intent) or plan performance (the degree to which decision makers apply the plan). In this research, we consider the relationship between performance–conformance by evaluating the implementation of compact activity centre policy in greater Brisbane. We examine two decades of changes to local land use planning regulations using content analysis, quantifications of permitted development intensity, and comparisons of actual land use changes with planned intent, to identify evidence of the use of metropolitan scale activity centre policy. We find that the activity centre policy performed well and was used as intended across the metropolitan area. However, despite strong performance, the policy conformed poorly in terms of achieving the expected outcomes. These findings highlight the importance of understanding plan implementation from both performance and conformance perspectives. While conformance evaluations are essential to connect planning intent to physical outcomes, understanding plan performance is also necessary to explain the results of conformance evaluations and whether conformance successes or failures were due to deficiencies with the plan itself or how the plan was used by key actors charged with its implementation.

当计划无效时：考虑大布里斯班紧凑型活动中心政策的实施绩效

计划实施的评估通常根据计划一致性（结果与计划意图一致的程度）或计划绩效（决策者应用计划的程度）来构思。在这项研究中，我们通过评估大布里斯班紧凑型活动中心政策的实施来考虑绩效与一致性之间的关系。我们使用内容分析、许可开发强度的量化以及实际土地使用变化与规划意图的比较来检查地方土地使用规划法规的二十年变化，以确定使用大都市规模活动中心政策的证据。我们发现活动中心政策表现良好，并在整个大都市区按预期使用。然而，尽管表现强劲，该政策在实现预期成果方面表现不佳。这些发现强调了从性能和一致性角度理解计划实施的重要性。虽然一致性评估对于将规划意图与物理结果联系起来至关重要，但了解计划绩效对于解释一致性评估的结果以及一致性的成功或失败是否是由于计划本身的缺陷或负责的关键参与者如何使用计划也是必要的及其实施。
