The network diagram is a logically schematic display provides graphical view for the project details like the tasks required to be performed, the relations between them and the duration’s estimations for the task itself and for the entire project including the earliest time to beginning the work in a every task the earliest predicted finishing date of the project. Network diagrams used for detailed planning, analyzing scheduling in project implementation and as a control tool in the monitoring and control phase. Two methods used to build the network diagram task-on-the-arrow (TOA) method and the recently one called the task-on-the-node (TON) method, or, the precedence diagramming method (PDM).
The relations between the two tasks called

Like when we drill critical well the owner prefer to use FS than SS to avoid using high tech tools where it is too expensive or lake of experience worker can use these tools effectively.
2. Management Constraint, these constraints imposed by the management team as a result of the market or business changes. In the oil field management constraints take a huge space while determining the dependencies, for example, the price of the crude oil push the management team to increase the drilling operations or decrease it, hire new rigs and start new project or release rigs and cancel projects.
3. Interproject constraints, it typically happens when deliverables from a task in one project required by another task in different project and this most likely to occur when a huge project divided into small projects. In the oil field the owner companies splits the project to more than one project to facilitate management like drilling, completion and production. But the relations between these projects still had influence on the dependencies in each one of them. For example the production equipment order and receive should done before the production project starts and after a certain tasks finished in the completion project.
4. Date constraints, when forcing a task to a particular schedule as a result of imposing start or finish dates. Three forms can be used for
Identify the system’s constraint itself. Learning that the true constraint is often a lack of availability of a specific skill or piece of equipment is helpful in quickly identifying the constraint, and the manager is encouraged to continually ask “why” to diagnose the constraint.
The concept of project scope may be one of the most ample in project management. It involves objectives, limits and intentions. Every requirement in a project as well as its characteristics must be dealt with when planning the scope. Even though it 's reasonable to say that every project is unique, the causes for which it fails are generally the same. And if you already know what these causes are, you can minimize the likelihood of problems being repeated and thus increase the chance of success.
Resource constraint: If a resource is shared by many projects or activities, it would be used in order of priority, thus leading to delay of activity or project with lower priority.
It impacts the timeline, milestones, and schedule of the project. That in turn will also impacts the budget of the project.
Interdependence conflicts: This happens when a person relies on someone else’s co-operation on output or input in order for them to get there job done. An example of this would be if I was late getting a required weekly report on production performance to my boss on time which he needs first thing on a Monday morning to send out to report to the entire business.
There are several different types of schedules that can be as simple as a “To do List” or as complex as a plan for a construction project.
2. Construct a table containing the project activities using the letter assigned to each activity, the time estimates, and the precedence relationships from which you will assemble the network diagram.
Less autonomy since the major specifications of the product is pre-defined and already committed prior to the detail design. This means the engineer cannot easily change the design if this is against the approved specification of the product.
• Prepare a 1,400- to 1,750-word paper that adds to the project begun last week. Check to ensure the project’s triple constrains are still valid. Address the following items in your paper: o Phase I – Update SOWa. • Using the SOW from last week, review and update it based on course material acquired during the last week. Include in the update the SMART requirements for the project. 1) • Identify the specific tasks required to complete each item listed on the SOW. Identify the resources required to accomplish each task.2) o Phase II – Project Schedule and Budget Update b. • Arrange the tasks into a schedule that takes into consideration the required dependencies between tasks. Computerized project management software is required. 1) • Present the schedule in either PERT or Gantt chart format. Identify the critical path through the network. 2) • Review the network results and compare to the project’s triple constraint. Specifically compare the following: 3) o Timing o Budget o Project specifications (scope and SMART)
Response: The Theory of Constraints focuses on making organizational decisions in situations in which constraints exist. The authors illustrate the Theory of Constraints (TOC) in production management.
An activity is any portion of a project which consumes time or resources and has a definable beginning and ending. For example, "laying of pipe" is an activity requiring the use of resource mainly effort. Activity may involve labour, paper work, contractual negotiations, machinery operations, etc. Commonly used terms synonymous with "activity" are "task" and "job".
A work breakdown structure (WBS) will develop for this project and the WBS is based on the project charter, scope statement, and other relevant information. Gantt chart and network diagram also will be well prepared for this project. While preceding the planning stage, the resource usage cash flow report will showing the hours each person is assigned to work on each task each week. Furthermore, the probability/ impact matrix and list of prioritized risks for the project will be included in the project
The core constraint of virtually every organization The Goldratt Institute has worked with over the past 16+ years is that organizations are structured, measured and managed in parts, rather than as a whole. The results of this are lower than expected overall performance results, difficulties securing or maintaining a strategic advantage in the marketplace, financial hardships, seemingly constant fire-fighting, customer service expectations being rarely met, the constraint constantly shifting from one place to another and chronic conflicts between people representing different parts of the organization, to name a
Formulating a network diagram, likewise alluded to as a logic diagram, in order to comprehend and envision how each task will continue is an extraordinary path to begin. It is a basic idea within project management planning that is effectively utilising as a part of application, commonly used as a part of assembling commercial enterprises, and also to outline and comprehend work processes are what service industries requires. It distinctively shows the rational rules for influencing tasks. (Holland, 2014) The development of the network diagram by incorporating the project team acquires an agreement of comprehension of how the undertaking ought to be accomplished. Nonetheless, giving a discussion to testing acknowledged
Uncontrolled scope changes are known as scope creep, which mostly occurs during project execution, which often result in rework, cost overrun and failure to deliver projects on time (Jordan, 2010).
