Managing Complex Work: projects and priorities

01

Before this course, and your project portfolio

In simple words

If you try to carry ten bags at once, you walk slowly and drop things. If you carry three, finish the trip and come back for more, everything arrives sooner. Projects work the same way.

Before this course: Productivity Systems: planning and focus (course 9.5.2). You already know capture lists and next actions, if-then plans, focus blocks, batching messages, breaks and how to test your own system. In Time Management & Productivity (course 9.5) you met the urgent/important matrix, time blocking and the planning fallacy. This course is for the next problem: many projects at once, other people's requests, and too little time for all of it. A line marked "Tip" is practical advice, not a research finding.

Key facts

A project is work with several steps and an end point ("launch the club website"). A task is one step ("buy the domain name"). A portfolio is the full list of projects you are responsible for, at work, at school and at home.
Work in progress (WIP) is the number of projects you have started but not finished.
Little's Law is a well-known rule from queueing theory, proved by John Little in 1961: L = λW. In plain words: average number of items in progress = average finishing rate x average time each item takes. Turned around: average time per item = items in progress / finishing rate.
What it means for you: if your finishing rate stays the same, more open projects means each one takes longer. It describes long-run averages in a fairly steady system, so treat it as a guide, not an exact forecast.
Tip: many teams use a WIP limit (for example "no more than 3 active projects") so new work waits until something finishes. Kanban boards often show this limit on each column.
Tip: a project that is "waiting" (on a reply, a part, a decision) still costs attention. Mark it clearly as Waiting with the date you will follow up.

Open projects	Projects finished per month	Average time per project (Little's Law)
8	2	about 4 months
4	2	about 2 months
2	2	about 1 month

Step by step

Write every project you carry on one page, one line each: work, school, home, volunteering, side projects.
Next to each, write its status: Active, Waiting, Someday or Done.
Count your Active projects. That number is your current WIP.
Look back 3 months and count how many projects you finished. Divide by 3 to get your monthly finishing rate.
Use Little's Law: WIP divided by finishing rate is your rough average time per project.
Choose a WIP limit lower than today's number. Move the extra projects to Someday or Waiting.
Check: your page shows every project, one status each, and a written WIP limit.

[Text on screen: L = λW] "Little's Law says the number of items in progress equals the finishing rate times the time each one takes."
[Screen: table, 8 projects vs 4 projects] "If you finish two a month, eight open projects take about four months each. Four open projects take about two."
[Host] "Same effort, faster finishes. Start less, finish more."

I'm learning "Managing Complex Work: projects and priorities" on The Future Market. Lesson 1: "Before this course, and your project portfolio".

What the lesson teaches:
- A project is work with several steps and an end point ("launch the club website"). A task is one step ("buy the domain name"). A portfolio is the full list of projects you are responsible for, at work, at school and at home.
- Work in progress (WIP) is the number of projects you have started but not finished.
- Little's Law is a well-known rule from queueing theory, proved by John Little in 1961: L = λW. In plain words: average number of items in progress = average finishing rate x average time each item takes. Turned around: average time per item = items in progress / finishing rate.
- What it means for you: if your finishing rate stays the same, more open projects means each one takes longer. It describes long-run averages in a fairly steady system, so treat it as a guide, not an exact forecast.
- Tip: many teams use a WIP limit (for example "no more than 3 active projects") so new work waits until something finishes. Kanban boards often show this limit on each column.
- Tip: a project that is "waiting" (on a reply, a part, a decision) still costs attention. Mark it clearly as Waiting with the date you will follow up.
- Open projects - Projects finished per month - Average time per project (Little's Law)

The exercise I'm working on:
Make your portfolio page today. Write your WIP, your finishing rate and the WIP limit you will try for the rest of this course.

I'm stuck. Please:
1. Explain the main idea in plain, simple words with one everyday example.
2. Walk me through the exercise one small step at a time. Ask me what I've done so far before giving the next step.
3. Don't just give me the final answer. Help me do it myself, and check my work when I share it.

I'm a parent helping my child (about 8 years old) with a lesson called "Before this course, and your project portfolio" from the course "Managing Complex Work: projects and priorities".

Here's what the lesson says:
If you try to carry ten bags at once, you walk slowly and drop things. If you carry three, finish the trip and come back for more, everything arrives sooner. Projects work the same way.

The activity:
Make your portfolio page today. Write your WIP, your finishing rate and the WIP limit you will try for the rest of this course.

Please explain this so an 8-year-old understands: short sentences, a fun everyday example, and no hard words.
Then give me 3 simple questions I can ask my child to check they understood, and a way to do the activity together, one tiny step at a time.
