+Design Service
+==============
The goal of the design process is to create all artifacts (models)
that are required to instantiate and manage resources, services,
generates artifacts that are used in other phases of design or when
instantiating or monitoring virtual functions.
-Design includes the following topics:
+The following figure show the different phases and tools involved in
+Onboarding, Design and Distribution process.
+

+
+**The "Core" Design Process includes the following steps:**
+
+**Pre-Onboarding**
+ A VNF/PNF/CNF Provider delivers its descriptor, model and
+ artefacts (e.g. HEAT template, Helm Chart), which will be validated
+ and packaged for onboarding to ONAP
+
+**(Resource)-Onboarding**
+ In the SDC a License Model is created, the VNF/PNF/CNF package imported
+ and a Vendor Software Product (VSP) is created
+
+**VF Creation and Testing**
+ A V(N)F, PNF or CR Model is created (a) import of a VSP or VFC
+ (b) manual creation and import of artefacts created via external
+ tools like the Controller Design Studio (CDS), responsible for the
+ Controller Blueprint Design
+ The created VF will pass a testing workflow to be used
+ in a Service Model
+
+**Service Design**
+ A Service Model is created as a composition of resources
+ (e.g. V(N)Fs, PNFs,...), Policies, Workflows,...
+ The created Service Model will ber certified and handed over to
+ the Service Distribution process
+
+**Service Distribution**
+ The Service Provider will distribute the Service Model to the
+ Runtime Service Catalog
+
+**The optional/additional Design steps are:**
+
+**VNF parameter assignment templating**
+ The objective is to automate the resolution of resources for instantiation
+ and any config provisioning operation, such as day0, day1 or day2
+ configuration.
+ The Controller Blueprint archive (CBA) is the overall service design,
+ fully model-driven, intent based package needed to design self service
+ provisioning and configuration management automation.
+ ONAP CDS (Controller Design Studio) is the controller that will process
+ the Controller Blueprint archive (CBA) at run-time.
+
+**Policy Design**
+ These are rules, conditions, requirements, constraints, attributes,
+ or needs that must be provided, maintained, and/or enforced.
+ At a lower level, Policy involves machine-readable rules enabling
+ actions to be taken based on triggers or requests. ONAP Policy framework
+ provides some policy models that are implemented and pre-loaded when
+ installing ONAP.
+
+**VNF LifeCycle Command templating**
+ APPC Controller Design Tool (CDT) is used for self-service onboarding of
+ VNF’s. VNF owners can create templates and other artifacts for APPC
+ Configure command (used to apply a post-instantiation configuration)
+ as well as other life cycle commands.
+
+**Workflow Design**
+ The purpose of the Workflow Designer is to enable designers to define or
+ modify workflows to support Service/Resource change management scenarios
+ executed by the Service Orchestrator.
+
+**Control Loop Design**
+ This phase includes the Design of a closed loop template and associate it
+ to a Service. The template represents the theoretical flow of the CL.
+ It generates a deployment artifact that can be ingested by the DCAE in
+ order to create the needed DCAE microservices in runtime.
+ The design is done in the SDC DCAE-DS (Design Studio).
+ The DCAE Design Studio enables to define and configure
+ the monitoring flows of DCAE.
+ The configuration and deployment of a Control Loop will be done with
+ Control Loop Automation Management (CLAMP) tool.
+
+The follwing sections will focus on the different Design steps:
