1 EXAMPLE TECHNOLOGY ITEM SYSTEM REQUIREMENTS SPECIFICATION (SyRS) EMERGENCY COMMUNICATION BUOY (ECB) PPI March 2018

2 FOREWORD This example System Requirements Specification (SyRS), developed by Project Performance International (PPI), is a part of PPI s documentation in support of its consulting and training activities with clients. The document is intended to serve as an example of the nature of a requirements specification defining a materiel item for end use, or an item for use in any other context. The requirements specification is intended to drive procurement and/or development of the item, as well as subsequent verification and acceptance. The requirements and organisations referred to in the example specification are fictitious. The materiel item SyRS specifies the solution-free requirements to be satisfied by any acceptable materiel item solution. The SyRS may also specify goals to be pursued during procurement and/or materiel item development (if applicable). The SyRS is the problem definition that drives: procurement, supply, materiel item development, verification of design within materiel item development, materiel item verification (e.g. acceptance test), and contractual acceptance of the materiel item, as applicable. The SyRS is the single most important artefact in procurement or development of an element which is the subject of the SyRS. Creation, capture and specification of the information content of the SyRS should be done with the utmost care, and with appropriate skills applied, to avoid problems such as: materiel items that do not satisfy the needs of the acquirer at all, or fall significantly short of satisfying the needs; avoidable inaccuracies in cost estimation; and delays due to contractual dispute, rework, or the need to undertake supplementary procurements. This example Materiel Item SyRS is for an Emergency Communication Buoy (ECB), with a contract value of about $5M for quantity 20 and a Whole of Life Cost of about $15M. The nature with the example item safety critical, developmental, and novel necessitated a fairly high standard of specification of requirements, 187 of them! The effort to prepare this requirements specification was about seven working days, about 0.05% of Whole of Life Cost. Many procurements are of non-developmental items, for which a much lower standard of specification will be most appropriate, perhaps 15% of the number of requirements needed in more demanding circumstances. The specification structure and sentence constructs of the example should still be employed. Where a procurement involves modification of a non-developmental item, an overall higher standard is needed for all of the requirements, since modifications can have unintended consequences. A standard of requirements approaching that of the example will be needed in areas subject to modification of the otherwise non-developmental item.

INTRODUCTION AND SCOPE 1.1 Identification SUBMARINE EMERGENCY COMMUNICATION BUOY SYSTEM REQUIREMENTS SPECIFICATION This specification describes the requirements for an Emergency Communications Buoy (ECB), also known as an Emergency Position Indicating Radio Beacon (EPIRB), to be acquired by the Royal Botswan Navy (RBN). Two variants of the Buoy are specified, as follows: a. Type A Buoy RF Buoy only; and b. Type B Buoy RF Buoy with Strobe Light. Unless otherwise stated, all requirements in 4. REQUIREMENTS apply to both the Type A Buoy and the Type B Buoy, therein referred to as the Buoy. Where a distinction applies, the terms Type A Buoy and Type B Buoy are used, as applicable. 1.2 Intended Use of the Buoy The Buoy is intended to be used primarily by the RBN Sub-Sea Command for submarine search and rescue purposes, in conjunction with Oberon and Collins Class submarines. The operational concept is that, in an emergency, a Buoy will be discharged from a Submerged Signal Ejector (SSE) of the submarine, rise to the surface, and at the surface, emit satellite and homing Radio Frequency (RF) signals, as described in detail in PPI , Example Emergency Communication Buoy (ECB) CONUSE. The Type B Buoy will also emit a strobe light, to aid visual sighting. The Type B Buoy is also intended to be used as a static exhibit at the H.M.B.S. Penguin Maritime Museum. 2. APPLICABLE AND OTHER REFERENCED DOCUMENTS 2.1 Applicable Documents The following documents form a part of 4. REQUIREMENTS, to the extent specified therein. Where a conflict exists between a requirement in 4. REQUIREMENTS and the content of an Applicable Document as listed below, the requirement in 4. REQUIREMENTS shall have precedence to the extent of the conflict. Note: Where the user of this specification identifies a conflict between 4. REQUIREMENTS and an Applicable Document, the user of this specification should inform the issuer without delay.
