ARIS PrototypeData Collection Exercise –Outcome & Lessons Learned

Sofronis PapageorgiouMarket Data Management Officer

. Background. 2nd Phase of the Pilot (ARIS Prototype). Data Collection Results. Lessons Learned

Outline

ACER’s REMIT Information System (ARIS)

Pilot Phases - Timeline

1st Phase

• July – November 2013

2nd Phase

• April – July 2014 (data submission)• August – October 2014 (preparation

for go-live)

. Further develop the data collection exercise, based on the draft implementing acts and using the “ARIS operational prototype” . Collect as much data as possible and, on this basis, define the scope of the first production release of ARIS (e.g. formats, data to be collected, interfaces supported). Provide a basic data sharing solution for NRAs. Provide a plan for ARIS go-live. Get estimates on key system requirements (e.g. number of users, number of transactions). Define validation procedures and controls

. Provide ACER with comments, suggestions and technical input on the data collection process (e.g. draft data fields, draft XML schemas etc.)

. Provide ACER with anonymised data in a format defined by ACER

ACER’s expectations from Pilot participants

Key milestones – Pilot Phase 2

Feb• Bilateral discussions with Pilot participants

March

• XML schemas provided to the Pilot participants• Pilot Progress meeting on 6 March• Feedback on proposed data fields and XML schemas

April -July

• ARIS open for data submission• Submission of anonymised data from Pilot participants• Sufficient amount of data collected

July• Pilot progress meeting

In the scope of the ARIS Prototype, ACER had provided the pilot participants with:

Access to an operational instance of the Data Collection module of ARIS

Three fully functional interfaces for uploading data (Web Services, SFTP, Web GUI)

A set of XML schemas corresponding to the different data types to be submitted (e.g. standard contracts and orders to trade, list of standardised contracts etc)

A comprehensive ‘ARIS Prototype User Guide for Reporting Entities’;

A dedicated Service Desk to support participants throughout the process

ARIS Prototype – Data collection exercise

Successful data uploads using all three interfaces

Successfully validated files, compliant to the shared XMLschemas

Satisfactory volume and variety of data types submitted

Collected feedback on the quality of the user guide

Preliminary Figures (analysis still on-going)

Note: In the process of correctly preparing the files for submission, the participants performed various testsubmissions. The same files might have been submitted multiple times until successful validation was achieved.It is important to note that these numbers are taken into account when calculating the total volume of files

ARIS Prototype – Outcome of data submission

Trade Data

Total Submitted Files Successfully Validated Files Success Rate

Service Desk Support

Total of 54 tickets handled

5 major categories identified

1. User Registration; request for account activation

2. XML Validation; information requests about the validation of the XML files against the XSD files uploaded to DCI system

3. Configuration Issues; support requests for the configuration of the tools necessary for file uploads (GPG, OpenSSL, SoapUI, FileZilla etc)

4. Invalid requests; invalid incidents, misinterpretation of system behaviour

5. Other; requests for information on system functionalities, upload statuses etc

ARIS Prototype – Service Desk Support

Data Quality

Analysis is on-going

Geographical/market coverage, quantity (time span) and quality factors are taken into consideration

Classification according to quality level and usability

Individual participants’ submissions analysed (bilateral follow-ups)

ARIS Prototype – Data Quality

Next Steps

Finalise Data Quality Analysis – On-going activity

Improvements to the ARIS Prototype – On-going activity

ARIS Prototype – Next Steps

Lessons Learned

Previous lessons learned from the 1st phase of the Pilot were taken into account and resulted in actions like;

Frequent bilateral interaction between ACER and Pilot participants, which facilitated planning and helped setting right expectations at an early stage

Set up of a dedicated Service Desk to support participants throughout the process

Significant effort will be required from market participants and reporting entities to properly prepare for data collection and submission (sufficient business/technical resources commitment is crucial)

ARIS Prototype – Lessons Learned

Lessons Learned (technical)

Sharing of relevant documentation (User guide, XML schemas, etc.) with Pilot participants early in the exercise enhanced participation and facilitated data submission, however;

documentation and the process of updating the documentation can be improved

simplification of XML schemas may be further explored

Timeline of the Pilot extended in order to address data quality concerns
