5-STEPS the ‘5 Steps To Ensure Project Success’ methodology is a proven process designed to focus the thinking of key Stakeholders onto the parameters required to achieve a successful project outcome. 5-STEPS uses the development of the schedule as a central plank in its approach to developing an effective project team and fostering positive stakeholder involvement.

The ‘5 Steps To Ensure Project Success’ process is designed as a logical sequence of activities (and importantly, agreements) but recognizes iterative passes through some of the key steps may be required to achieve agreement. The five sequential steps are:
The 5–STEPS methodology requires each step to be completed, validated and "signed off" before moving onto the next.
Beeline Diagramming Method (BDM). Beeline represents the overlapping relationship between two consecutive tasks by the shortest straight line (the beeline). BDM connects any point in the predecessor to any point in the successor. Download the paper.
The Chronographic Diagramming Method. The Chronographic Model uses the concept of internal divisions and internal measurement as a function of production and converts relationships into internal divisions and internal relationships related to a quantity of workload, thus delaying or anticipating the start of the second activity in order to respect the predecessor production.

Earned Duration (ED) / Count the Squares (CTS) is a method of assessing schedule performance based on the comparing the duration of activities 'as-planned' and 'as-accomplished'. In the 1970s CTS was used where each day of an activities duration was counted as ‘1’ and the cumulative planned days was compared to the cumulative actual days work accomplished. ED modifies this basic process by adjusting the 'earned duration' for each activity based on the current expected duration. The fundamental weakness in this approach is its assumption that one days work on one activity in a barchart is equivalent to any other day's work on any other activity, whereas the the resources assigned to one activity in a may be 1 person per day and another 15 people per day.
Earned Schedule (ES) adapts traditional Earned Value data to provide a reliable prediction of a project's expected completion date. ES overcomes the limitations in ED/CTS by using the value of the work accomplished as a reasonable proxy for the resources being used to accomplish the work. Download the Article.
Momentology focuses on measuring the momentum of work on the project. Each section of a project has its momentum as does the overall project. The loss of momentum is a reliable predictor of a delayed completion. See WP1036 Momentology.
Rolling Wave Planning is the process of progressively increasing the detail in a schedule as more information becomes available. Work in the near term is planned in detail, later work is left as higher-level planning components. Detail may be added in layers; initially as planning packages (reflected in the schedule as a single activity), then as a number of work packages (each reflected in the schedule as a single activity), then as detailed activities. The key requirement is that the schedule is fully detailed before work starts on that portion of the project. See WP1060 Rolling Wave Planning.
Schedule Density, is similar to rolling wave planning but designed for modern software. Initially the overall project is planned at Low Density; work planned to occur within the next year or so is scheduled at Medium Density, and work planned to occur in the next 3 months is scheduled at High Density and defines in detail who will be doing what, where and when (normal schedule activities). See WP1016 Schedule Density.
Timeboxing, is a simple process used to measure the completion of a defined amount of work in a fixed period, plus or minus an allowed variation (the 'time box'). Commonly used in Scrum and other Agile methodologies to define sprints or iterations. See WP1020 Timeboxing.
Barcharts or Gantt Charts. A simple graphical
representation of the project schedule, the concept was
originally developed by Joseph Priestley in 1765. This
type of chart lists the tasks to be performed on the
vertical axis, and time intervals on the horizontal axis.
The the horizontal length of the bars in the graph shows
the duration of each activity. Barcharts may be either a
static drawing or a presentation of a dynamic schedule. See our list of
Critical Chain is a method of planning and managing projects that puts the main emphasis on the resources required to execute project tasks. Work is scheduled to occur when needed, using an optimistic duration estimate. Overall completion is protected by the use of time buffers. See WP1050 Critical Chain.
Critical path method. The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities to determine when each activity can start and finish. The critical path is determined by identifying the longest series of dependent activities controlling a completion date, and measuring the time required to complete them. See our list of CPM tools.
Line of Balance (LOB) is a method of showing the repetitive work that may exist in a project as a single line on a graph and compares the rate at which the work has to be undertaken to stay on schedule with the actual rate of production. See WP1021 Line of Balance. This basic concept has been expanded to encompass 'time-location' charts, 'chainage' charts and 'location based scheduling': See some of the available software tools.
Multiple Activity Charts (or Multi-Activity Charts) are a very useful tool for understanding the flow of work in a cyclical process and as a consequence understanding which resource is controlling the overall progress. See WP1025 Multiple Activity Charts.
RD CPM™, The Relationship Diagramming variation of the Critical Path Method of schedule analysis developed by Fredric L. Plotnick. Numerous scheduling tools are certified as incorporating RD-CPM. See WP1035 Relationship Driven CPM.
