3. Application of ECSS standards in Space projects 3. a – Tailoring (1/8) What is tailoring q ECSS standards are made applicable at each level of the customer-supplier chain by adapting them to the specificities of the project, at this level. This adaptation process is called tailoring. q Tailoring shall be performed by the customer, at each level of the customer-supplier chain. It is a requirement of ECSS-S-ST-00 (the higher standard in the ECSS hierarchy) q Project requirements within the PRD are therefore composed by 2 sets: ² Requirements specific to the project ² ECSS Requirements, once tailored to the project ESA Standards Division – August 2014 ESA UNCLASSIFIED – For official use Introduction into the ECSS standardization system Slide 4

3. Application of ECSS standards in space projects 3. b – Pre-tailoring (1/4) Why, What is and status q Tailoring of the whole set of requirements for a specific application has demonstrated to be a non-trivial very heavy task. q It is however acknowledged that a number of requirements may not be meaningful for specific type of project or for specific phases of a project. q It was therefore considered of ECSS interest to identify possible “types of products” and establish the associated applicability of standards/requirements. This view is shared by all ECSS Space Agencies, and considered of crucial importance by Eurospace. q The impact of pre-tailoring is that it will reduce dramatically the “Baseline for tailoring” (input to steps 3 and 4 in the general tailoring process). It will NOT eliminate the need of the final tailoring by the customer. q Pre-tailoring and tailoring have different actors: ² Pre-tailoring will be “pre-cooked” list of standards, and a “pre-cooked” list of requirements in every standard subject to pre-tailoring (published at the time of producing the standard). ² Tailoring is to be done specifically by every project by the project itself. q Currently, only pre-tailoring for ECSS-Q-ST-20 has been published. By end 2015, all the ECSS standards subject to pre-tailoring will be done.

3. Application of ECSS standards in space projects 3. b – Pre-tailoring (2/4) Pre-tailoring of the list of requirements per applicable standard (before tailoring step 4): In respect to pre-tailoring, standards may fall in 3 categories: - Category C (Complete): The standard needs no pre-tailoring, because it is applicable as a whole to a particular type of product, during a given phase. Example: Black anodizing. - Category I (implicit): The standard has been built such that the pre -tailoring is implicit to its structure. Example: ECSS-E-ST-10 -03 Testing, which clauses are organized as “Testing for space segment equipment”, “Testing for space segment element”, “Prelaunch testing”. - Category E (Explicit): The pre-tailoring of the document is included (per product type and per project phase), in explicit tables within the document.

3. Application of ECSS standards in Space projects 3. c – Requirement management tools: DOORS ECSS database (1/1) q What DOORS is: ² DOORS is a commercial Software from IBM for requirement management ² It is designed for management of requirements during their lifecycle, including flowing down to (sub)contractors q DOORS and ECSS: ² ECSS has produce a DOORS database of all ECSS requirements ² Now this database is under SB approval. Once approved, it will be available for any ECSS member ² The application and the database with all ECSS (standards and requirements) in version C or later, is available under request to ESA q Pros and con’s: Advantages: ² Powerful. It permits full requirement configuration control, at all levels in the customer-supplier chain, including full traceability to the original requirements. Disadvantages: ² It needs a license not usable universally. ² Expensive, both the license and in terms of learning time ESA Standards Division – August 2014 ESA UNCLASSIFIED – For official use Introduction into the ECSS standardization system Slide 12

3. Application of ECSS standards in Space projects 3. d – Feedback (1/2) q The process relies on individual inputs provided to ECSS, from each ECSS partners ² Change request (at organizational or individual level) ² Feedback from projects q Each ECSS organization (e. g. ESA) shall implement its own internal Feedback Process è Then Feedback Inputs are collected and merged by the ES and make them available to TA for assessment. q Potential output of the feedback process are: ² Change Request to existing standards ² NWIP (add/modify/split or group standard) ² TA recommendation to improve overall ECSS system (e. g. improve Website, add/remove discipline/branch, standard cancelation, modify drafting rules, . . . ) ESA Standards Division – August 2014 ESA UNCLASSIFIED – For official use Introduction into the ECSS standardization system Slide 13

3. Application of ECSS standards in Space projects 3. d – Feedback (2/2) q Feedback from ECSS user (which includes Space Agencies and Eurospace) is required by the ECSS-S-ST-00 “System description and implementation” (=> i. e. is a requirement to the users) q The Feedback process is defined in D-00 document (=> i. e. is a process for ‘developers’) q At the present, feedback will only apply for Project using ECSS Issue C (or later) q The overall feedback process relies on three pillars ² C-ARM analysis (at Project ITT level) ² Inquiry board and LL & feedback from project at major reviews (PDR/CDR/FAR/CR) ² ECSS Questionnaire (on-line version & TA triggered campaigns) ESA Standards Division – August 2014 ESA UNCLASSIFIED – For official use Introduction into the ECSS standardization system Slide 14
