Come explore a world of project management possibilities! In this session, you'll discover tools and techniques that are the envy of other businesses. From network diagrams to CPMs, PERTs and Gantts - there's a wealth of options for any type of project. With these resources at your fingertips, take on projects with confidence knowing success is within reach.
Network diagrams are a great tool to illustrate the complex relationships between tasks. AoN and AoA styles effectively help viewers to visualize how jobs flow in sequence or parallel, allowing them to get an overview of what needs completing quickly and easily. Whether you want people-centric visuals or task outlines, both types of network diagram can provide informative pictures that everyone involved can understand.
Activity on Node diagrams offer a powerful solution to project planning by representing tasks as distinct nodes and mapping out the priority of each with arrows. With this approach, essential details such as duration and predecessor/successor dependencies can be illuminated in one concise visual representation - helping teams quickly assess difficulty levels or identify blockers that need solving along the way. A special feature is also available of marking start / end points through rounded edge rectangles for gauging progress over time – allowing stakeholders an easy-to-digest snapshot when making critical decisions about your projects!
Activity on arrow diagrams offer an intuitive way to display tasks, highlighting the milestones in a project along clear paths. While circles are used for nodes (or milestones), with text above and/or below solid arrows describing individual activities, all must be connected at some point to time zero - thus forming our timeline from beginning to completion!
Activity diagrams are a useful way to display workflows and tasks. Solid arrows show the true progression of activities, while dashed ones signify dummy activities that don't affect duration or completeness - they simply demonstrate precedence between actions. Nodes can also be given identifiers for reference but usually this is just an alphabetic letter due to limited space on either side of the arrow.
Project management can often seem like a complex task, but luckily there's Critical Path Method (CPM) to help make it easier. CPM is an approach used for analyzing project tasks and durations in order to identify the fastest route from start to finish of your project - known as the critical path. This approach examines relationships between activities and their respective timings, providing you with insight into how best manage each step along towards successful completion!
To keep a project's duration on schedule, it is essential to determine its critical path. This can be done by creating a network diagram including all the tasks and their dependencies. For short projects, you may even spot the key activity at first sight; however for more complex undertakings manual calculations are necessary to discover what sets up deadlines that must not be missed in order maintain your timeline!
This project involves a tricky web of tasks that must be navigated to complete in the most efficient way possible. In order for A and B to begin at the same time, C has to wait until completion of A before kicking off; following this F can start as soon D is finished, making sure not too leave any loose ends - then comes G which marks the end! With each phase taking different amounts of days ranging from 8-23 days respectively it's important we understand how much effort will go into completing this project sensibly with estimated durations laid out ahead.
Crafting a Network Diagram is all in the details! With CPM, you need to fill each node with information that forms an intricate web. From start time and duration to predecessors and resource requirements - every part of your network diagram must be carefully constructed for optimal success.

Keep your project on track by staying aware of the key start and finish points: Earliest Start (ES), Earliest Finish (EF), Latest Start (LS), Latest End (LF) - as well as any available Slack time.
Starting Network Diagram
Here is the network diagram for the project listed above. As you can see, all precedence relationships have been identified, and the activities and durations are labeled.
Ready to dive into the world of project management? The forward pass through a network is an integral part. Start by zeroing in on the earliest start and finish times for each activity, beginning with your very first one (or ones). To ensure accuracy, you must account for every path that emerges from each node - if two or more arrows enter it, take note: use the highest completion time associated as starting point in next node. We'll make sure all stones are turned over before visualizing its results on our handy-dandy updated diagram!
Starting from the final activity and working backwards, the backward pass through a network can provide crucial information about each individual task’s latest start time & finish time. By mirroring its forward counterpart, this method gives insight into efficient scheduling of activities for maximum productivity.
The project's conclusion is not determined until the last activity G has been completed. Using 47 days as its earliest finish time, it marks the starting point for our backward pass to determine how much wiggle room we have between activities in order to keep up with schedule expectations. We compare each of G's successor tasks' latest start times and use whichever is smaller as our goal finish date before recalculating what must happen upstream accordingly!
Once you've worked out the network diagram, it's time to assess how much extra cushioning each activity has. To do this, calculate the slack - subtract either an activity's earliest start or finish times from its latest. With your calculations done and presented in a visual representation of the project -- voilà! Now you have starkly laid-out insight into which tasks have wiggle room that can be exploited if needed. Take task E above; with 9 days' worth of Slack assigned to it on paper, there is potential for completing said task between times 26 through 47 without causing any delay on overall delivery dates!
With no slack in the sequence of activities, it is essential to identify your project's critical path. This visibility provides a clear understanding for everyone involved - simply highlight nodes or insert double-arrows and voila! A red line will show you exactly which steps are on the critical path – from B through D to G in our example.
In the 1950s, two pioneering techniques for time management planning were born - PERT and CPM. While they can both be used to create network diagrams, perform backward/forward passes, identify slack times and determine critical paths- what sets them apart lies in activity estimation methods. Unlike CPM which relies solely on one predefined estimate per task accomplished; PERT accounts for uncertainty by utilizing three separate estimates (most likely time; optimistic & pessimistic). This allows it to provide greater accuracy when scheduling activities with uncertain outcomes.
When the same task is performed repeatedly, Most Likely Time reflects how long it usually takes. Optimistic and Pessimistic Times present estimates for what can be expected under favorable or unfavorable circumstances respectively. Using a program like Program Evaluation Review Technique (PERT) gives you an understanding of your project's uncertainty while assuming that these variations follow beta distribution probability patterns.
Completing a task can be tricky to predict. Thankfully, the PERT Formula is there as an effective tool! With it, you simply plug in your three estimates - most likely time (Tm), optimistic time(To) and pessimistic time (Tp). The formula averages them out and gives you one expected completion date: Te. This easy calculation lets everyone know when they should expect results!
Estimate the future of your project with precision! The PERT method is the ideal tool for calculating expected time durations during initial phases, when there can be a high degree of uncertainty. Gather information from subject-matter experts and resources to make sure you have realistic values for 'optimistic', 'most likely' and pessimistic estimates - plug them into the formula above and get an accurate estimation about how long it will take to complete each activity in your journey. Unlock deeper insights at every step so that no surprises stop you on your expedition towards success.
The Value of PERT
If there are a lot of questions surrounding tasks and milestones, or if the project is entirely new to you and your project team, it may be best to use PERT to determine the critical path, in which case you would need three estimates as opposed to one per activity. Knowing you are going to use the PERT method will help you avoid duplication of effort. Instead of creating one estimate in the beginning and then going back to create three estimates, simply knowing that you will perform PERT will set you on the right estimation path from the beginning.
Gantt charts can help manage and monitor the progress of any project. They are used to display milestones, activities, estimated durations and allocated resources in a visual format that is easily understood. Milestones provide an essential reference point so your team members and sponsors alike have an immediate insight into how far along the project has come. To show these stages clearly on a Gantt chart they appear as solid coloured diamonds – like those shown on this handy hand-drawn representation!
