When it comes to project management, two terms that often cause confusion are PPS and PS. While they may sound similar, they have distinct meanings and applications. In this blog post, we will delve into the differences between PPS and PS, helping you gain a clear understanding of each term and how they are used in the project management field.

What is PPS?

PPS stands for Project Portfolio Selection, and it refers to the process of determining which projects should be included in an organization’s portfolio. It involves evaluating various project proposals and selecting those that align with the organization’s overall objectives, resources, and strategic goals.

PPS is typically carried out by senior management or a project management office (PMO) using a structured approach. It helps ensure that resources are allocated efficiently, risks are minimized, and the organization’s strategic goals are effectively supported through appropriate project investments.

Key features of PPS include:

  • Evaluation of project proposals
  • Prioritization and selection of projects
  • Alignment with strategic goals
  • Resource allocation

What is PS?

PS, on the other hand, stands for Project Scheduling. It refers to the process of creating a detailed timeline for project activities, considering dependencies, resources, and constraints. PS involves breaking down the project into smaller tasks, estimating their duration, and establishing the sequence in which they should be completed.

Project scheduling is an essential component of project planning and execution. It helps project managers and team members understand the project’s timeline, dependencies, and critical paths. Through effective project scheduling, organizations can optimize resource allocation, manage risks, and ensure timely project delivery.

Key features of PS include:

  • Create a detailed timeline
  • Identify dependencies
  • Allocate resources
  • Establish task sequences

How are PPS and PS different?

The main differences between PPS and PS can be summarized as follows:

  • PPS focuses on project selection, while PS focuses on project scheduling.
  • PPS is concerned with choosing the right projects for an organization’s portfolio, while PS is concerned with creating a detailed timeline for a specific project.
  • PPS is typically performed at a higher level by senior management or a PMO, while PS is performed by project managers and team members.
  • PPS involves evaluating project proposals and aligning them with strategic goals, while PS involves breaking down tasks, estimating durations, and establishing task sequences.

How are PPS and PS applied in project management?

PPS is applied in the early stages of project management to ensure that the right projects are chosen and allocated appropriate resources. It helps organizations prioritize projects, evaluate their feasibility, and align them with the overall strategic goals.

PS, on the other hand, is applied throughout the project’s lifecycle. It starts during the planning phase when project activities and dependencies are identified. It continues during project execution when tasks are scheduled, resources are allocated, and progress is tracked. Effective project scheduling ensures that the project stays on track and is delivered within the agreed timeline.

In conclusion, PPS and PS are two distinct concepts in project management. While PPS focuses on project selection and portfolio management, PS deals with project scheduling and timeline creation. Understanding their differences and applications is crucial for effective project planning and execution.
