Page 1 / 5 24.1- SCHEDULING METHODOLOGY 24.1.1. PURPOSE The following best-practice guideline provides the STO Project Controls Team with a defined methodology for scheduling, to accurately identify the cost, timeline and resource requirements for their STO project Plan, and to establish a method of controlling the Execution Phase of the STO project with DMS (Dynamic Schedule Management) and CGS (Computer Generated Scheduling) to meet, or exceed the KPI Targets agreed upon by the STO Sponsor, STO Manager, STO Steering Committee and the STO Project Controls Team. This will provide Partners and Shareholders with the confidence that the Cost-Time-Resource-Triangle (CTRT) is optimized and controllable. te: Schedule is a verb, not a noun. The Plan, therefore, is the product of Scheduling. The phrase, Things never go according to Plan, is, for the most part correct, because we can only see the future in terms of Logic, as in, What do we do next?, not in terms of, When do we do it?. To be specific, we know that the bundle of an Exchanger cannot Logically be extracted from its Shell until the Exchanger Cover and Head have been removed. When we execute these Activities, however, is something we cannot predict; therefore, it s important to remember that Scheduling needs to be Dynamic, in order to re-calculate Plans that are realistic to the changing conditions. This principle theory forms the basis for the Scheduling Methodology. BEST PRACTICES A formalized Scheduling Methodology must be established and incorporated into the STO Management Process, supported by a Step-by-Step Phased process (see page 5) with Scheduling Software, Polices, Procedures and Checklists. Best-practice implementation requires formal training and on-going coaching to ensure consistent results. A formal QA/QC Plan Review Process, consisting of a checklist, must be incorporated into the Scheduling Methodology, with hold-points at the beginning and the end of each Phase. Dynamic Schedule Management (DSM) must be incorporated into the Scheduling Methodology, which includes Programming Parameters. Programming must be done by a designated person, allowing the computer software to do the majority of scheduling to produce a Plan. WBS (Work Breakdown Structure) must be created to reflect the hierarchy of the facility as per the following Elements: Level I Plant
Page 2 / 5 24.1.3. GUIDELINE Level II Unit Level III System / Process Level IV Equipment Type / Discipline Level V Work Order Task (Short Description) Front-load the Plan by 10% - 15% to establish early access to equipment for Inspection and Repair, while maintaining sufficient resources should Extra Work and/or Added Work be identified during the Execution Phase. Use these Shift Schedules for best performance: 7 x 12 x 2 Longest Path Activities / Process Operators 7 x 10 x 2 Inspection Activities 7 x 13 x 2 Indirect Supervision 6 x 10 x 2 Mechanical / E/I Trades Offset Shifts to avoid congestion at the Permit Office, e.g., Maintenance 07h00, Capital Projects 08h00, and Confined-Space 07h30. Productivity Factors must be applied to each Resource, Contractor and Work Type to ensure the Plan is realistic. Do not develop a Plan in isolation. To establish a good Plan it s necessary for Stakeholders to be involved, e.g., Contractors, Inspection, Operations. Maximize Pre and Post Activities - move as much work outside the Execution Phase window as possible. Track all work by Work Types: rmal, Added, Extra, Ignored, Late and Cancelled. All work to be completed within the Execution window must be integrated into the Plan, i.e., Capital Projects, Operations Shutdown and Start-up Plan. There can only be one Plan. Establish the Execution Phase early (Longest-Path) to provide Management, Marketing and Stakeholders with an estimate of production outage duration and number of maintenance days available to schedule remaining work. Use Gantt Charts only for analysis; do not distribute to the Field for purposes of Execution. Print Shift Reports on a different color of paper each day (Sunday to Saturday) Overview Scheduling to establish a realistic Plan for the STO project Execution Phase is one of the least understood and utilized elements of STO management; and unfortunately, one of the most critical to its successful outcome. The primary reason for this is the failure to establish a Scheduling Methodology, and to implement its Best-Practices through training and coaching (Typical Project Management Scheduling Techniques are not sufficient for STO Projects). Given today s Technology, coupled with a Best-Practice Methodology, the ability to optimize a Plan, and to control the Execution Phase, with the least amount of resources at the lowest cost, has never been better.
Page 3 / 5 1 St Phase The objective of Phase 1 is to establish the project within the Project Management Software; to establish the WBS (Work Breakdown Structure); to establish each Phase of the STO project, and to create a Level III Plan to determine the Execution Phase duration. The Level III Plan is created using the Operation s Strategic Plans for Shutdown and Startup in conjunction with the Tasks which make up the Longest-path, based on 7 x 12 x 2 Shifting and Zero Float. During this Phase, the Programmer, a.k.a. Scheduler, will establish the Layouts, Calendars, Resources, Filters and Codes required for programming, and will begin entering the detailed Plans from each PJP (Planned Job Package) at each Level V WBS Element (Work Order Task) as logical Activities; each with estimated duration, crew, materials, information, equipment and tools. When 85% of this data is entered the Programmer will be ready to move on to Phase 2. 2 nd Phase The objective of Phase 2 is to Program, Schedule and Calculate an optimized Plan in preparation for the Pre/Execution/Post Phases of the STO project. During this Phase the Programmer will establish using a variety of What-if scenarios, in conjunction with Stakeholders input and Computer Software the most optimized Plan possible; Cost- Time-Resource-Triangle (CTRT). During this Phase, the Programmer, a.k.a. Scheduler, will create all Reports related to Execution and Earned-value Performance, in Tabular and Gantt format. Just prior to saving a Baseline to establish the Planned S-Curve Values a QA/QC review will be executed to ensure all possible scenarios have been considered (Risk Analysis) to ensure data integrity and Plan optimization. 3 rd Phase The objective of Phase 3 is to control, that is to say, to drive the Plan to meet the established KIP Targets in an ever-changing environment. The majority of scheduling is done during this Phase, which is done using the DSM (Dynamic Schedule Management) process supported by CGS (Computer Generated Scheduling) to produce a realist Plan for each Shift of the STO project. During this Phase the Project Controls Team will trend and forecast the Earned-Value Performance and make adjustments to Productivity Factors (PF) to control the outcome of the STO project.
