What This Guide Offers. The content in this guide will help partners integrate the Cisco Lifecycle Services approach into their service practice helping to increase . Around 7 hours of free training video content. In the first session titled “Design Methodologies and Approaches” the presenters discuss PPDIOO. Clarifying PPDIOO So here is a clarification that I had posted in the past regarding the first four phases of the PPDIOO framework.

You can also properly make a plan for changes in infrastructure and changes in requirements for resources.
PPDIOO also improve the networks availability because we are using a sound and solid network design and all alone the way we are validating our network operations. It also speed-up access to network resources and applications. One important thing to note that your network life cycle may not necessary to go through all the phases in the define order.
It is quite likely to go into preparation phase, planning phase, design phase and implementation phase and then you may have to go back to planning phase to make some changes and then have to go at design phase forimplementing changes into design. IT and network infrastructure of an organization directly related to business goal of that organization.
Normally in this phase board of directors or top management of organization are involve, as a network designer you need to list down all the possible infrastructure for ppdiio technology that you can deploy for that company. You can build a business case in this phase which can provide you the financial justifications for overall network strategy.
You can start the plan phase by information gathering and list down all the requirements including all services requirement and security requirements. You need to ensure your network security by planning and designing cisck network with best practices. You also need to look at network management process, you may need to work on fault management, configuration management, performance management, security management and accounting ppdloo in order to finalizing the network plan.
In plan phase you need to analysis all the cicso and plan to implement the best practices, you need to create a project plan which helps you to manage your tasks, identify the responsible parties, define rules, set your milestone and work with your project managers and vendors to Identify the resources that you need for designing and implementation of network.
You can also follow this project Plan for remaining phases of network life cycle. Like the previous phases, design phase is based on requirement of any business as it is parallel with technical requirements, it includes high availability, and making sure you have redundancy, failover and fault mechanism at software and hardware level.
In design phase we create and generate the different lists, diagrams ppxioo as per project plan and after completion the above stuff, update the project plan with design phase modifications.
The PPDIOO network lifecycle
You can simplify the design phase with following steps:. Here you define the major features and characteristics of your network, also select the tools for monitoring ciscp managements.
Characterizing of existing network is an information gather process. For the designing the network topology the best approach that the Cisco recommends is top down approach, it mean start from layer-7 of OSI model to layer CCDA is all about the designing the network and mostly focus on prepare, plan and design phase you can ppdioi the different design model and methods from CCDA course.

Implementation phase is related to configuration and operations, here you define the all the configuration of your device and also identify the time related to these configurations. In implementation phase if you want to change anything then you must communicate it to all team members and also made the proper modifications in Plan and design phase accordingly, also define the proper guidelines and provide the RFCs if required.
And any change that you make in implement phase must be tested before going to next phase. Operation phase is the actual test of your network design, you need to identity the network related fault. Monitor the working of different devices and network equipment.
Optimize phase is a proactive network management, you can identify and resolved issue before they move to entire network base of your good design. In optimize phase you can modify network design if problem are coming out.

For solving problem you can go back to your previous phases for example prepare and plan phase, make the changes there and then again test the changes in operate cosco optimize phase.
