This article aims to describe a new approach to a specific project management technique called Critical Path Method (CPM).
According to Project Management Body of Knowledge (PMBOK), CPM is a method used to estimate the minimum project duration and determine the amount of scheduling flexibility on the logical network paths within the schedule model[1]. Given scheduled activities for a project that need to be completed in a specific order, multiple task sequences can be defined. CPM helps us to determine the longest sequence of tasks in the project, which will be also the shorter possible project duration. Thus, the main steps of CPM will be described, providing a brief guidance on how to apply the method so to obtain the optimal project duration.
However, a traditional CPM schedule is not realistic, because it assumes unlimited resources, some of which are highly limited in practice[2]. Therefore, a different approach of the same technique, called Resource-constrained Critical Path Method (RCPM), will be presented. By providing a step-by-step RCPM procedure, the article will focus on the advantages that this method can offer compared to the traditional Critical Path Method. The paper will then conclude with observations about the benefits and limitations of both CPM and RCPM, highlighting differences and similarities between the two techniques.

Overview
What is Project Management?
The definition of 'project' can be found in the Project Management Body of Knowledge: it is a temporary endeavor undertaken to create a unique product, service, or result (PMBOK). Ergo, a project is any series of activities and tasks having a specific objective to be completed within some specifications (critical path analysis programming method without network diagram), such as start and end dates, specific goals and limits, established implementers responsibilities, budget and schedule (critical path method in estimating project duration).
The management of a project is essential to ensure that these activities are completed in accordance with all the given specifications and expectations (Applications of Critical Path Method in Project Management). Therefore, 'project management' can be defined as the application of knowledge, skills, tools, and techniques to project activities to meet the project requirements (PMBOK). It is thus the process of defining, planning, organizing and controlling tasks in order to deliver a project in time and at a reasonable cost.
