1. Process Control: Burndown chart, fishbone chart, Gantt chart

1) Burndown Chart

Noun Explanation: Burndown chart (burn down chart) is a visual representation of the work that needs to be done before the project is completed. The Burndown chart has a y-axis (work) and x-axis (time). Ideally, the chart is a downward curve, with the remaining work completed, "Burnt" to 0. Burndown charts provide a public view of the work progress of project team members and business owners. This word is often used for agile programming. Since the Burndown chart is a statistic for the remainder of the time, we can infer the approximate progress and trend of the current work with the same number of people, and management can use the graph to grasp the progress of the development and make the right decision, and can anticipate the risks and adjust the plan accordingly.

Legend:

My understanding: In my opinion, burndown charts are given to programmers to let them know their progress, workload, what has been done and how much work remains to be done. The main thing is to see the management is the boss, so that managers can better control the time, urging and speed up the rhythm, so that programmers can better and faster to complete the task, and the same group of programmers on different projects are likely to show the same Burndown chart, because the human inertia is similar, So old Burndown charts are likely to predict and analyze new projects and prepare and prevent them in advance.

2) Fishbone diagram

Noun Explanation: Fishbone diagram is also called causal analysis or Ishikawa map, it looks like a fish bone, problems or defects (that is, the consequences) marked "fish Head" outside. A fishbone is grown on the fish bone, which lists the possible causes of production problems by the presence of chance. Fishbone diagrams help explain how each of these factors interact. It can also show how each of the possible causes is occurring in sequence over time. This helps to tackle the problem.

Legend:

My understanding: I think Fishbone diagram is a detailed division of all the problems, we discussed together, found a lot of software problems and shortcomings, good, write on a piece of paper, and then in this way will be the main secondary division out, at a glance at the same time give us a clearer idea and solve the problem of primary and secondary, And the error anomaly will continue to increase, the advantage of this diagram is that you can leave space to make more fish bones, convenient and quick.

3) Gantt Chart

Noun Explanation: Gantt Chart (Gantt chart) is also called Gantt Chart, bar chart (bar chart). It is a graphical representation of the sequence and duration of activity for any particular item, graphically through the activity list and timescale. It is basically a line chart, the horizontal axis represents the time, the vertical axes represent the activity (the project), and the line represents the completion of the planned and actual activities throughout the period. It visually shows when a task is planned, and how the actual progress is compared to the plan requirements. This makes it easy for managers to figure out what remains to be done in a task (project) and to assess the progress of the work.

Legend:

My understanding: The Gantt Chart is a graph of completion, he clearly summarizes the completion of the project, at what time, who did what, and How much time, can be clearly seen from the Gantt chart, This can be used as a reference at the end of the award, and a Gantt chart from the previous project can be used to predict the new project and then list it to better standardize our initial plan, and I think it would be better to introduce quality analysis here, for example, the quality of this step is good, The Gantt chart is painted red, the difference is green, so that we can more intuitively analyze the shortcomings and advantages of our project.

2. From a range of angles, compare a class of software (3 software)

Range Software	Everyone		Weibo
Scope of application, age	All	All	All
Circle Range	Medium (divided by school)	Small (according to the Circle of people)	Big (there is a circle)
Use heat	Small (once also OK, now hehe)	Big (daily must do three things, eat sleep brush)	(Always pay attention to celebrity news, social News)
Function metrics	Poor (because of the use of less, so. ）	Excellent (because you can chat to show up for a single user)	Good (chat interface is too obscure, mainly social hotspots attract others attention)
Access to others	Semi-restricted (need to send notification and wait for reply, some can go directly to view)	There are restrictions (need to be notified and wait for a reply if the user does not agree to view their information)	No Limit (no notification, direct attention is required)
Friendly interface	Don't understand (this really does not understand)	Very friendly (simple, one is an item)	General (see, review, praise, hair, so far will be these four)
System Testing	It often collapses (it really is ...). ）	Good (rarely crashes and messages are pushed in time)	Very good (rarely crashes, messages can arrive in time)
Existence of available data potential	Great (inclusive of all high school college experiences after 8090, cell phone number, business card)	Less (just a small circle of dialogue)	Very little (this is also the reason why so many micro Bo, who knows who is who ah!!) ）
Summarize	Everyone is commonly known as the school, defeated in its limited circle, the school is not like the social circle of mutual integration, is only an isolated small group, coupled with user software and other do not good, so not commonly used, but the data potential is great, if the change way, must make a difference.	Is now the main means, its advantage is to protect people's privacy to a great extent, my friends can see my circle, non-friends will not see, which also reduces our awareness of the increasingly complex network.	Weibo is characterized by the ability to comment casually, without any consequences. Can vent the mood dissatisfaction, the above has a variety of people's dynamic, celebrities or friends, to meet our curiosity and a lot of girls dynamic pursuit star dream.
Future forecast	Not really.	Maintain the status quo and steadily improve	Maintain the status quo
