+The following figure show the different phases and tools involved in
+Onboarding, Design and Distribution process.
+
+|image1|
+
+**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.
+
