Second, the number of people without construction management and technical experience is not good.
Provide guarantee for the realization of these problems.
Zebra schedule software prepares project plan 6 The depth of the schedule is the first level schedule (milestone node), which is generally used when the work content is not clear.
We must know what to do before we can manage.
Get it in the menu bar Oh, pay attention πγ.
You must understand the construction process, know what to do first and then what to do (process flow), know what resources to be equipped (human, material and machine), and be able to estimate the work efficiency of human and machine and the consumption of materials.
The key is that it can be “quantified”; The fourth step is to estimate the time required for the work according to the remaining quantities, existing resources and human resources and machine consumption; Step 5: arrange the work according to the process flow; Step 6: if it is found that the planned time exceeds the construction period requirements, generally, the resource investment will be increased to shorten the construction period of key work; In rare cases, the construction period target will be adjusted; Step 7: format.
Who should prepare the project plan? The project manager should be the preparer of the plan, because our plan is not to deal with the owner or look good, but has practical guiding significance.
In any case, the manager must ensure that the project runs under the control of the plan.
There is a saying in management that “the premise of all management is scope management”.
Level II schedule (mainly reflecting the completion of divisional work) is generally used by the construction unit when preparing the construction organization design.
We should find out the more reasonable path according to various restrictions and adjust the path at any time according to various changes.
Never expect a project to be “all right” if it is planned only once when it starts.

After the change, we should re prepare the plan and always form the plan around the core of “goal”.
Generally, rigid constraints (constraints) are time, that is, duration.
What are the preparation steps of the schedule? The first step is to know the construction period objectives, the work contents (and the process flow) and the resources you have; The second step is to arrange these work contents in spatial order; The third step is to decompose the work contents according to the time (process flow).
Here is a full zebra schedule software learning material + free software.
The plan should take into account the change.
The plan is an optimized path from the starting point to the target point.
What does the complete schedule include? Schedule is the main pulse, from which the extension includes resource allocation plan (human, material and machine), capital plan, cost plan and so on.
The decomposition is determined according to the level of preparing the plan.
Without any constraints, we will list duration as rigid constraints.
2.
We should regard change as a part of the plan.
The three-level schedule (implementation schedule) is generally detailed to sub items (pile number and number of floors) to guide the actual production on site.
Any decision on the project should refer to the factors of the construction period plan, and all resource allocation and adjustment should focus on the line of the plan.
3.
The project manager must have a way of thinking to keep the overall plan of the project in mind at any time.
By preparing the schedule, the project manager can grasp the overall situation and find problems, which is the key.
How do you think the plan can’t keep up with the change? There is a Chinese saying that “plans can’t keep up with changes”, so many managers think that plans are useless or useless.
Time, space, resources, process and cost are all issues to be considered in preparation (each may form a limitation).
7.
What are the constraints of the schedule? Generally, we will make plans according to the known target construction period (according to the time limit), or according to the resource and space constraints.
For example, we know that there are n paths to reach a target point.
Third, people without software operation ability can’t compile well (the implementation means that must be mastered, just as language is the carrier of thought, software operation can realize from thought to reality, and communication and sharing can be realized through this clear and accurate expression).
There are software with unified preparation requirements for the schedule: Zebra schedule software, unified type: bar chart, double code network diagram, unified format: consistent form of table, unified elements: divisional and subdivisional works, quantities, construction period, etc The key to the implementation of the schedule is that as a project manager, we must upload and release the schedule and let all project participants know, which is one of the keys.
No matter how many changes, we must have such a path that is clearly known by all members of the project.
We must constantly adjust the plan (in most cases, the adjustment is the path to achieve the goal, and in a few cases, the goal will be adjusted), but the goal should always be “locked” in the process of adjustment.
Ensure that the project schedule is known by all functional departments of the company in order to provide corresponding support; Make sure that project members know and keep the same rhythm.
1.
A complete schedule must be formed after overall consideration of various factors.
The second is to regularly and irregularly check the difference between the actual progress and the planned progress, and find out the problems.
8.
A plan without considering constraints has no practical significance.
This is very meaningful for the preparation of the plan, because any plan should cover all the remaining quantities and other auxiliary work hidden behind the quantities.
5.
Who can’t make up the construction schedule? First, people who have no awareness of the overall situation of the project and systematic thinking are not well prepared (they can give consideration to the end point and boundary when considering problems).
