1 Introduction

1.1 Purpose of the document

This document describes the plan for the Signal Processing Concept Design Review (CoDR) for the

Square Kilometre Array (SKA) project.

1.2 Scope of the document

This document will describe all matters related to the review itself. It will include logistics

surrounding the review as well as a preliminary agenda.

1.3 Date and Place

The Signal Processing CoDR will be held on 14th and 15th April 2011 at the University of Manchester,

Manchester, UK.

3 Purpose and Expected Outcome of the System CoDR

The signal processing CoDR is the review of the work conducted at element level during the Concept

Phase. The phase, as well as the design review requirements, are described in more detail in [1].

During the Concept Phase of the project, the signal processing engineering process will be initiated

by conducting investigations into, amongst others, the particular technologies being utilised,

technology trends, technology options, work already done and being done by precursors, design

studies and other pathfinder arrays, and results obtained from this work. Preliminary investigations

into the signal processing set of requirements, the interfaces and the risks will also be conducted.

The CoDR will be conducted to evaluate:

The overall progress,

Whether the technical adequacy obtained during the concept phase is at a sufficient level of

maturity to allow the Signal Processing Element to move into the next phase,

Whether all Signal Processing Element aspects of the project have been covered and where

gaps exist, whether adequate measures have been identified to address the shortcomings.

The expected outcome of the review is the establishment of the signal processing concept baseline

by conclusion of the signal processing level concept phase. Following the successful conclusion of

the review the next phase, the Signal Processing Element definition phase, will be initiated.

WP2‐040.020.011‐PLA‐001 Revision : 2

2011‐04‐06 of 17

More specifically the Review Panel is requested to consider the following questions:

1. Are the requirements complete, and sufficiently defined for this stage of the project?

2. At the concept level, is the element/subsystem presented capable of meeting the

requirements?

3. Have interfaces to other aspects of the system been adequately identified and defined at

this stage of the program?

4. Are the options proposed to be carried forward credible and are the presented data and

information in support of each option credible?

5. Have all the necessary aspects of the specific element/subsystem been considered and

addressed during the review or are there gaps and/or shortcomings?

6. Does the risk profile appear reasonably detailed and assessed for this stage of the program?

7. Do the stated risk controls and proposed mitigations appear reasonable and executable?

8. Is the overall plan (including the identification of the tasks, effort, resources, costs, schedule

and risk mitigation needed) to complete the subsequent project phases credible?

These questions are to be within the context of SKA1 but with consideration of extensibility to

SKA2

4.2 Review Process

The External Review Panel is expected to review the CoDR documentation prior to the actual review.

Any questions, comments or queries sent to the SPDO SP domain specialist (W.Turner) in advance

will be recorded and be dealt with during the review. Questions, comments or queries posed during

the review will be recorded and will be attempted to be addressed during the review. In the event

that any issue cannot be dealt with during the review, it will be recorded as such and the SPDO will

address these outstanding issues as soon as possible after the review.

4.3 Roles and Responsibilities

The SPDO shall

• Distribute the last of the documentation to the External Reviewers no later than two weeks

before the review date;

• Record all questions, comments and queries raised before and during the review;

• Respond to questions, comments and queries before, during and after the review;

• Record the responses to the questions, comments and queries;

• Organise and support the review meeting:

• Provide the necessary facilities for the meeting;

• Respond to agreed Actions within the agreed due dates;

• Compile an overview report to the PrepSKA Board and the SSEC after the review.

The External Review Panel Chairman shall

Organise and lead the External Review Panel;

Review the documentation;

Raise questions, comments and queries before and during the review related to any part or

aspect of the project;

Prepare and issue the External Review Panel Report, together with a list of the agreed

Actions;

WP2‐040.020.011‐PLA‐001 Revision : 2

2011‐04‐06 of 17

The External Review Panel Members shall

• Review the documentation;

• Raise questions, comments and queries before and during the review related to any part

or aspect of the project;

• Support the Chairman in the preparation of the External Review Panel Report;

Observers:

Observers are deemed to have more than a passing familiarity with the work being reviewed and

to have had some opportunity to pass comment prior to the Review. In order to capture views

that develop during the Review process, but to allow the formal procedure to complete in the

time allocated, COARs may be drafted by Observers and an opportunity to present them to the

SPDO immediately following the Review is envisaged. As this right is available to Observers,

questions or statements from the floor of the Review will be discouraged. Questions from the

panel will be handled by the presenter which may, at his/her discretion, call on members of the

audience to assist with answering the question.

The Observers are therefore invited to:

• Attend the review;

• Provide written feedback with regards to any aspects of the review, including the

documentation, in COAR format after the review;

• Assist with answering questions from the review panel if requested to do so by the

presenter.
