Annex A. Methodology

This Annex summarises the methodology developed by the OECD to assess regulatory authorities’ governance arrangements, drivers of performance as well as their performance measurement matrices. The methodology was prepared based on the experience of regulators participating in the OECD Network of Economic Regulators and the present report constitutes its thirteenth application to a regulatory body. Other reviews spanning a number of sectors and countries include: Colombia’s Communications Regulation Commission (OECD, 2015[1]); Latvia’s Public Utilities Commission (OECD, 2016[2]), Mexico’s three energy regulators (OECD, 2017[3]), (OECD, 2017[4]), (OECD, 2017[5]), (OECD, 2017[6]); Ireland’s Commission for Regulation of Utilities (OECD, 2018[7]); Peru’s Energy and Mining Regulator (OECD, 2019[8]); Peru’s Telecommunications Regulator (OECD, 2019[9]), Peru’s Transport Infrastructure Regulator (OECD, 2020[10]) Ireland’s Environmental Protection Agency (OECD, 2020[11]), Portugal’s Energy Services Regulatory Authority (OECD, 2021[12]) and Brazil’s Electricity Regulatory Authority (OECD, 2021[13]). The methodology has been adapted since its first application to learnings throughout the review process and is adjusted to take into account specific needs and contextual characteristics of each regulator, sector and jurisdiction.

The analytical framework that informs this review draws on OECD work on measuring regulatory performance and the governance of economic regulators. OECD countries and regulators have recognised the need for measuring regulatory performance. Information on regulatory performance is necessary to better target scarce resources and to improve the overall performance of regulatory policies and regulators. However, measuring regulatory performance can prove challenging. Some of these challenges include:

  • What to measure: evaluation systems require an assessment of how inputs have influenced outputs and outcomes. In the case of regulatory policy, the inputs can focus on: i) overall programmes intended to promote a systemic improvement of regulatory quality; ii) the application of specific practices intended to improve regulation, or iii) changes in the design of specific regulations.

  • Confounding factors: there is a myriad of contingent issues that have an impact on the outcomes in society which regulation is intended to affect. These issues can be as simple as a change in the weather, or as complicated as the last financial crisis. Accordingly, it is difficult to establish a direct causal relationship between the adoption of better regulation practices and specific improvements to the welfare outcomes that are sought in the economy.

  • Lack of data and information: countries tend to lack data and methodologies to identify whether regulatory practices are being undertaken correctly and what impact these practices may be having on the real economy.

The OECD (2014[14]) Framework for Regulatory Policy Evaluation starts addressing these challenges through an input-process-output-outcome logic, which breaks down the regulatory process into a sequence of discrete steps. The input-process-output-outcome logic is flexible and can be applied both to evaluate practices to improve regulatory policy in general, and also to evaluate regulatory policy in specific sectors, based on the identification of relevant strategic objectives. It can be tailored to economic regulators by taking into consideration the conditions that support the performance of economic regulators (Box A A.1).

The OECD Best Practice Principles for Regulatory Policy: The Governance of Regulators (OECD, 2014[15]) identifies some of the conditions that support the performance of economic regulators. They recognise the importance of assessing how a regulator is directed, controlled, resourced and held to account, in order to improve the overall effectiveness of regulators and promote growth and investment, including by supporting competition. Moreover, they acknowledge the positive impact of the regulator’s own internal process on outcomes (i.e. how the regulator manages resources and what processes the regulator puts in place to regulate a given sector or market) (Figure A A.1).

The two frameworks are brought together into a Performance Assessment Framework for Economic Regulators that structures the drivers of performance along the input-process-output-outcome framework (Table A A.1).

For regulators, performance indicators need to fit the purpose of performance assessment, which is a systematic, analytical evaluation of the regulator’s activities, with the purpose of seeking reliability and usability of the regulator’s activities. Performance assessment is neither an audit, which judges how employees and managers complete their mission, nor a control, which puts emphasis on compliance with standards (OECD, 2004[16]).

Accordingly, performance indicators need to assess the efficient and effective use of a regulator’s inputs, the quality of regulatory processes, and identify outputs and some direct outcomes that can be attributed to the regulator’s interventions. Wider outcomes should serve as a “watchtower”, which provides the information the regulator can use to identify problem areas, orient decisions and identify priorities (Figure A A.2).

The analytical framework presented above informed the data collection and the analysis presented in the report. The present report looks at the internal and external governance arrangements of Peru’s Water and Sanitation Services Regulator (Sunass) in the following areas:

  • Role and objectives: to identify the existence of a set of clearly identified objectives, targets, or goals that are aligned with the regulator’s functions and powers, which can inform the development of actionable performance indicators;

  • Input: to determine the extent to which the regulator’s funding and staffing are aligned with the regulator’s objectives, targets or goals, and the regulator’s ability to manage financial and human resources autonomously and effectively;

  • Process: to assess the extent to which processes and the organisational management support the regulator’s performance;

  • Output and outcome: to identify the existence of a systematic assessment of the performance of the regulated entities, the impact of the regulator’s decisions and activities, and the extent to which these measurements are used appropriately.

Data informing the analysis presented in the report was collected via a desk review, two fact-finding missions and a peer mission:

  • Questionnaire and desk review: Sunass completed a detailed questionnaire which informed a desk review by the OECD Secretariat. The Secretariat reviewed existing legislation and Sunass documents to collect information on the de jure functioning of the regulator, and to inform the fact-finding missions. This questionnaire was tailored to Sunass, based on the methodology already applied by the OECD to other regulators since 2015 and on the participation of Sunass in former OECD research such as the 2021 Water Governance in Peru publication.

  • Fact-finding missions: the first fact-finding mission focused on meeting Sunass internal teams and was conducted by the OECD Secretariat between 3 June – 11 June 2021. The second fact-finding mission took place between 21 June – 25 June 2021 and focused primarily on meeting external stakeholders. These missions were the key tool to collect and complete the de jure information obtained through the questionnaire with the de facto state of play. The work of the fact-finding missions tailored the PAFER methodology to Sunass’s features. Information collected was completed and checked with Sunass for accuracy. Both missions were virtual due to the context of the COVID-19 pandemic.

  • Peer mission: the peer mission took place between 6 September – 10 September 2021 and included peer reviewers from Italy, Portugal and the United States, in addition to the OECD Secretariat. This mission met with key stakeholders in Sunass as well as externally. At the end of the mission, the team discussed preliminary findings and recommendations with senior management from Sunass to test their feasibility. This mission was conducted remotely via videoconference.

During the fact-finding and peer missions, the team met with Sunass leadership team as well as a number of staff from across the institution. In addition, the team met with government institutions and external stakeholders, including:

  • Presidency of the Council of Ministers (PCM)

  • Ministry of Housing, Construction and Sanitation (MVCS)

  • General Directorate of Environmental Affairs (DGAA)

  • Ministry of Environment (MINAM)

  • Ministry of Development and Social Inclusion (MIDIS)

  • National Water Authority (ANA)

  • Technical Organisation for the Administration of Sanitation Services (OTASS)

  • Private Investment Promotion Agency (ProInversion)

  • National Institute for the Defense of Competition and the Protection of Intellectual Property (INDECOPI)

  • Municipal Technical Authorities (ATMs) of Cusco and Los Baños del Inca

  • Regional Goverment of Housing, Construction and Sanitation of Arequipa, Ayacucho and Tumbes

  • Congressional Commission of Housing, Construction and Sanitation

  • Sedapal

  • EMAPA Chancay

  • National Association of Sanitation Service Providers of Peru (ANEPSSA)

  • Rural Sanitation Services Administrative Boards (JASS) of Namora, San José and Santo Tomás

  • Representatives of Users Councils (East, Lima and South)

  • World Bank
