The Data Isaac

One wild value can ruin a whole chart. Check the unit before you delete the row. Someone may have entered dollars instead of cents.

A to do list shows what is still waiting. Keep a done list too. You may be moving more than you think.

Do not send the angry reply at once. Stand up and get some water. A short pause can save a long repair.

A story can make data easy to remember. It can also hide facts that do not fit. Use the story to add light, not cover things up.

Open your dashboard on a small screen. The key number may vanish below the fold. Design for the screen people really use.

Good meeting notes are an act of care. Write the choice, the owner, and the next step. Everyone leaves with less guesswork.

Count your rows before and after every join. A sudden jump may mean one row found many matches. That small check can save the whole report.

Your totals should have a home to return to. Match them against the source report. If they do not agree, stop and find out why.

If a task returns every week, make it easier. Write a short checklist once. Your future week will thank you.

One million dollars sounds huge. At a small company, it may change the whole year. At a large company, it may be a small line item. Size needs context before it has meaning.

A rate needs its full count nearby. Five out of ten is not the same as five of ten thousand. Show the base so people can judge the result.

A useful recommendation needs the word because. Try this because the data shows that. The reason turns advice into a clear choice.

Senior analysts do not rush to make a chart. They spend time asking what the number means. That pause saves a lot of bad work later.

Before you build the chart, ask one person a question. What will you do if this number goes up? If nothing changes, the chart may not be needed.

Keep a small record of work you are proud of. Add kind words, hard problems, and useful results. You will need the proof on a quiet day.

A falling line is not always bad news. Wait time, errors, and costs should go down. First ask which way success is meant to move.

The scariest question in any meeting is: "How exactly did you calculate this number?" Keep your notes clean. You will always need to explain your math three weeks after you completely forgot how you did it.

Every filter changes the story. A report for one region is not the full company. Show the active filters where people can see them.

Ending a big report with just a summary is a missed chance. Give the team three clear actions they can take tomorrow. Information is useless if it just sits on a shelf. Drive the final point straight into the real world.

Asking for help is not a weak move. It is often the shortest path out of confusion. The trick is to show what you tried first. That makes help easier to give.
