Edited at 2023-12-06 23:08:01This Valentine's Day brand marketing handbook provides businesses with five practical models, covering everything from creating offline experiences to driving online engagement. Whether you're a shopping mall, restaurant, or online brand, you'll find a suitable strategy: each model includes clear objectives and industry-specific guidelines, helping brands transform traffic into real sales and lasting emotional connections during this romantic season.
This Valentine's Day map illustrates love through 30 romantic possibilities, from the vintage charm of "handwritten love letters" to the urban landscape of "rooftop sunsets," from the tactile experience of a "pottery workshop" to the leisurely moments of "wine tasting at a vineyard"—offering a unique sense of occasion for every couple. Whether it's cozy, experiential, or luxurious, love always finds the most fitting expression. May you all find the perfect atmosphere for your love story.
The ice hockey schedule for the Milano Cortina 2026 Winter Olympics, featuring preliminary rounds, quarterfinals, and medal matches for both men's and women's tournaments from February 5–22. All game times are listed in Eastern Standard Time (EST).

Project time management
definition
The processes required to ensure the project is completed on time
Purpose
1. Guarantee that the investment will be recovered and profits will be obtained within a certain period of time 2. Coordinate the investment of resources 3. Ensure resources are available when needed 4. Complete the project within a strict deadline
content
activity definition
Concept: further decompose and refine the project work breakdown structure, and identify and define the various project specific activities required to achieve the project goals.
process
in accordance with
1. Project work breakdown structure 2. Project scope statement 3. Historical information Collect and accumulate information in the early stage, similar to project information. 4. Project constraints 5. Project assumptions
method
1. Decomposition
Further breakdown and refinement into specific activities based on WBS
2. Define platform method (prototype method)
Using activity lists from similar projects as prototypes, add or delete activities to define the activities for the new project
Output results
1. Project activity list: all activities that need to be carried out
2. Relevant supporting details: Various detailed documents and information that support and explain the activity list
3. Updated work breakdown structure (generally none) Relevant project management documents such as cost estimate documents need to be updated
Activity sequencing
Concept: Determine dependencies between activities and form documents The sequence relationship of project activities is called logical relationship
include
Process relationship, hard logical relationship
Organizational relationship, soft logical relationship
in accordance with
1. List of project activities 2. External dependencies 3. Specified dependencies 4. Intrinsic correlation 5. Constraints and assumptions
Methods and tools
1. PDM method (Priority Diagram Method) uses nodes to represent activities, and uses arrows representing logical relationships to connect the nodes to draw a network diagram. Also called single code network diagram (AON)
Relationship and network diagrams
Drawing steps
① List activities, including logical relationships between activities
②According to the activity list, draw nodes without immediate predecessor activities first
③ Confirm that all the immediately preceding activity nodes of each activity have been drawn on the diagram, then connect the activity node with the immediate predecessor activity using an arrow line.
④ Repeat the above steps until all activity nodes of the entire plan are drawn.
⑤Draw the start node and end node
2. ADM method (arrow diagram method) uses arrow lines to represent activities, and connects activities at nodes to represent logical relationships. Also called the double code network diagram method (AOA)
Activity list and network diagram
composition
Drawing steps
① Determine the successor activities based on the known predecessor activities;
② Determine the start node position number and end node position number of each activity from left to right;
③Draw a preliminary network diagram based on node location numbers and logical relationships;
④ Check the logical relationship for errors. If it does not match the known conditions, you can add virtual activities to correct it.
3. Conditional graph method
Graphical review technology allows the existence of loops (such as experiments that must be repeated multiple times) or conditional branches (such as only when errors are found, the design needs to be modified and re-implemented)
4. Model network
Some standard network diagrams are available, which can include the entire project's network or a subnetwork of a portion of the project.
Output result:
Project network diagram
Activity duration estimates
Concept: Estimating the possible duration of various activities that have been identified in the project
in accordance with
1. Project activity list 2. Constraints and Assumptions 3. Quantity requirements of resources 4. Resource quality requirements 5. Historical information
Methods and tools
1. Expert evaluation method 2. Analogy
3. Simulation method: The triangular simulation method is relatively simple. First make an estimate of the duration of a single activity, and then make an estimate of the entire project duration.
Single activity duration
Three estimated times: optimistic time a, pessimistic time b, and most likely time m. Formula: d=(a b 4m)/6 standard deviation = (b-a)/6 squared
Total expected construction period
The duration of each individual activity is added together
Output results
1. Estimated project activity duration 2. Basis for project duration estimation 3. Updated activity list
Project schedule preparation
Concept: Analysis and preparation of project plans based on project activity definition, activity sequencing, activity duration and required resources. Define the start and end dates of the project, as well as specific implementation plans and measures
in accordance with
1. Project network diagram
2. Estimation of activity duration
3. Resource requirements and resource sharing instructions
4. Project work system arrangement
5. Various constraints
⑴ Mandatory date: The project owner or other external factors may require the project to be completed by a certain specified date.
⑵Critical events or major milestones: The project owner or other stakeholders may require certain deliverables to be completed by a certain specified date.
6. Advance and lag requirements for activities
Methods and tools
1. Mathematical analysis methods
⑴Critical route method: Network planning technology that determines the logical relationship between activities in the plan and the duration of the activities
Plan review technology: The logical relationship between the activities in the plan is certain, but the activity duration is uncertain. Generally, the weighted average time is used to estimate and evaluate the possibility of completing the project on schedule~
Graphic review technology: The logical relationship between activities and the duration of the activities are not certain, and are handled based on probabilities~
2. Simulation method
3. Resource level approach
4. Project management software
