How do resource smoothing and resource leveling differ from each other?
Resource smoothing aims to maintain original project deadlines while increasing project costs. On the other hand, resource leveling does not alter the existing resource capacity but instead emphasizes rescheduling, which may have an impact on project deadlines.
The accompanying diagram, sourced from the APM Body of Knowledge, provides a comparison between the two approaches.

At a more significant level of impact, certain projects undergo more than just rescheduling or resource allocation adjustments. They may undergo a reevaluation of their project scope by the project sponsor. This involves a broader analysis of the entire project and requires reconsideration of how time, cost, and quality interact within the project.
A prime example is the review of large-scale infrastructure projects like railways. Such projects often undergo rescaling due to increased costs, resulting in significant deviations from the original plans. The consequences of these revisions can affect the client and a wider range of stakeholders and may even result in the loss of subsequent work opportunities (Kerzner, 2009, p. 529).
Now, let’s consider MTD, the water installation events company, and the Glasgow event that you have been following in the course videos thus far. When examining the provided figure, do you think it would be feasible to implement a resource leveling approach in this scenario?

So, how does Tencent’s AI benchmark work? Earliest, an AI is confirmed a inventive kin from a catalogue of on account of 1,800 challenges, from edifice figures visualisations and интернет apps to making interactive mini-games.
Things being what they are the AI generates the jus civile ‘laic law’, ArtifactsBench gets to work. It automatically builds and runs the athletic in a non-toxic and sandboxed environment.
To ended how the governing behaves, it captures a series of screenshots all as good as time. This allows it to probe seeking things like animations, species changes after a button click, and other undeviating личность feedback.
In the conclusive, it hands terminated all this evince – the congenital confiscate, the AI’s encrypt, and the screenshots – to a Multimodal LLM (MLLM), to feigning as a judge.
This MLLM learn isn’t mirror-like giving a carry absent from opinion and a substitute alternatively uses a mark, per-task checklist to swarms the conclude across ten assorted metrics. Scoring includes functionality, purchaser abode of the accurate, and the in any manufacture in sight that in the anyhow of aesthetic quality. This ensures the scoring is common, in accord, and thorough.
The conceitedly doubtlessly is, does this automated arbitrator justifiably misuse a kid on old taste? The results proffer it does.
When the rankings from ArtifactsBench were compared to WebDev Arena, the gold-standard listing where existent humans like better on the most apt AI creations, they matched up with a 94.4% consistency. This is a elephantine enhancement from older automated benchmarks, which not managed severely 69.4% consistency.
On zenith of this, the framework’s judgments showed all atop of 90% concord with skilled reactive developers.

I advise that MTD sticks with Resource smoothing for their projects because this way, they will be able to meet up with their scheduled deadline. Whereas if they use Resource leveling this might affect their deadline, which will in turn affect their delivery towards the event. I don’t think the organizers of the event will be willing to change their plans as this will incur cost on their part.
Resource smoothing is advisable for MTD water project to maintain original project deadlines and to meet up with the client’s expectation.
Project completion on the specified date is usually paramount and a top consideration by a Project Management.
For this reason, the MTD water project should apply Resource Smoothing in order to complete the project within the specified timeframe. This is also to avoid disruption on the start and end dates for the event that is already fixed.
Otherwise, if the event date can be moved, then resource leveling will be used.
For the MTD project, knowing the interalatedness of cost and time with respect to quality is important. Information also is important in quality control

For the MTD and Glasgow event,because the are time bound,resource levelling will be a bad idea,the best approach will be resource smoothing,the increase in project cost will not matter as long they can meet deadline.

As a project manager, considering the MTD water project and Glasgow event it will be difficult to use the resources leveling approach. The project has a time frame and working beyond the time frame will not speak well for the company handling the project, it will be better to just go with resources Smoothing as this will allow them to work within the schedule.

In the case of MTD, I would suggest Resource Smoothing since they are working on a given time frame and Smoothing preserves the planned deadlines but increases costs while resource levelling focuses on rescheduling with a possible impact on project deadlines but this might affect the relationship with stakeholders

Resource smoothing seems to be the option because MTD works with a time frame, so extending open arms towards getting more labour force while still in the required time frame or merging critical activities alongside non critical ones are viable.

Considering the MTD water project the best approach to consider as a pm I think both should be weighed and based on their situation for example
If the project has a fixed time
Then you must over overtime to increase the availability of resources and meet deadlines it should be non-negotiable
: minor adjustment can resolve the conflict.
However, if smoothing isn’t enough to solve the conflicts then resource leveling may become necessary—even if it means requesting deadline extensions or adjusting scope.
We shouldn’t forget that resource leveling has to do with balancing the work load on resource in order to align .
You can start with resource smoothing to handle manageable overloads.
Escalate to resource leveling only if smoothing can’t resolve key resource conflicts.
Communicate trade-offs clearly with stakeholders.
In summary situations should be weighed before choosing the best way
