A Best Practices Example

PDIOO - Planning Design Implementation Operation and Optimization Summary. Understanding the value and using PDIOO methodology can greatly ease new platform deployment. This widely accepted procedure, outlined below, typically ensures the smoothest, most efficient path to the rollout of new technology.

Planning and Pre-Planning

Before we move into the first stage of the PDIOO model, tangible goals and requirements as to what the benchmarks of success will need to be established. More importantly, we need to be able to definitively describe and be able to answer these questions before we begin. Some objectives to think about are - What do you want to accomplish from this project? How will this be measured? What is an indicator of success?

Once the team fully understands why the project is being undertaken, we can move into the PDIOO model. Moving to the first PDIOO stage, an infrastructure assessment is conducted to ensure your network will support the new applications. That the new applications will be compatible with existing systems/devices and your new systems will perform as planned. As the assessment is performed, we will:

  1. Include all network elements in the plan, including hardware, software, security, IP addressing, links and cabling, backups, power and existing network services. Analyze your legacy systems and current network utilization to understand potential performance issues and requirements.
  2. Proper planning provides us with a successful conversion to the new or replacement systems, boosts the resiliency of the network, identifies the resources needed for successful implementation, and aligns the application with your business requirements.

Design

Once the assessment is complete, we move on to the design phase. We will evaluate several different design alternatives that meet the customers' requirements. During the design planning process, based upon vital input from the customer we will keep in mind such critical factors as: Security, redundancy, scalability, and integration to existing systems, downtime, cutover time and proper training. At Leading Edge, we project manage all these factors to minimize downtime and maximize the rollout strategy benefits. By considering these factors, it will ensure the ultimate design accommodates all users' requirements and reduces management costs.

Implementation

An implementation plan is vital in the PDIOO process, as it helps ensure that the deployment delivers all its desired functionality, while recognizing a minimum amount of disruption. This plan should include any associated network staging and ready-for-use plans. Acceptance testing may also be necessary for a smooth implementation. The benefits of this PDIOO stage are numerous. Implementation planning will minimize migration issues, streamline the deployment process, and reduce service disruptions, ensuring that all the critical elements are in proper working order.

Operation and Optimization

Finally, it is time to undertake the last two PDIOO stages: operations and optimization planning. Operations' planning protects your networking and IT investment and provides your staff with the ability to avoid problems, expedite problem solving and maximize your platforms benefits. Optimization planning helps your platforms deliver the best possible performance, thus decreasing network issues and reducing long-term costs.

Together, these stages will simplify expansion and the rollout of new applications and systems, while ensuring the quality of the network and its user applications, focus staffing and training needs, facilitate problem solving and lower the total cost of ownership.

Replacing, upgrading, and improving existing systems are a necessary lifecycle step in the Information Technology continuum. It can be a strategic benefit and help you respond competitively to the demands of both customers and trading partners. By following the PDIOO methodology, you can ensure your technology solutions will be successful and cost-effective, easily managed and deployed throughout their life cycle.
