Is Your Information System Working For You or Against You?

"Without data, you're just another person with an opinion." — W. Edwards Deming

Every day, you collect information; sales numbers, customer details, expenses, production records. But here's the critical question: Is that information helping you make better decisions, or is it just adding to the noise?

The difference between a business that grows and one that struggles often comes down to one thing: an information system that works for you, not against you. This post will teach you what an information system is, why it matters, and how to build one; starting today.

📋 In This Post, You'll Learn:

What an information system really is (simple definition)
The 4-level pyramid: from basic transactions to strategic decisions
How to assess if YOUR current system is working
Practical first steps to build your own information system today

The Story of Two Business Owners

👩🏾‍🌾 Eyerus runs a small poultry farm. She keeps records in a notebook; prices paid for feed, money received, eggs collected. But the notebook is messy. Entries get skipped. At month's end, she stares at it. She knows she sold a lot of eggs. But did she make a profit? She's not sure. Every decision feels like a guess.

👨🏾‍🌾 Tsegaye runs a similar farm. Three months ago, he started recording every transaction in a simple spreadsheet on his phone. Every egg. Every bag of feed. Every sale.

Now, Tsegaye knows his profit per egg. He spotted feed prices rising and adjusted early. When a micro-grant opportunity appeared, he had the numbers ready to apply.

Same work. Same market. Different results.

The difference? An information system that works FOR them.

What Is an Information System?

"An organized way to collect, store, and use data to make better decisions."

That's it. It doesn't require expensive software. Your system could be:

A notebook with consistent daily entries
A spreadsheet you update every evening
A simple app on your phone

🔑 Key Insight: An information system has five parts: People (you, your team), Processes (daily routines), Tools (notebooks, apps), Data (the facts), and Decisions (what you do with it).

🔺 The Information Pyramid

Your roadmap to information mastery

Each level builds on the one below it

Level 1: TPS (Transaction Processing Systems) — Record every sale, expense, and event. This is your foundation.

Level 2: Functional Systems — Organize data for specific areas: accounting, marketing, operations.

Level 3: DSS (Decision Support Systems) — Ask "what if?" and analyze possibilities before acting.

Level 4: ESS (Executive Support Systems) — See your whole operation at a glance through dashboards.

💡 Remember: You can't have good decisions (Level 4) without good organization (Level 2). And you can't have good organization without good records (Level 1). Start at the bottom.

Is Your Current System Working?

Ask yourself these five questions:

❓ Question 1: Can you find any document from last month in under 1 minute?

❓ Question 2: Do you know your exact profit margin on your top product?

❓ Question 3: Can you prove your impact to donors or lenders with numbers?

❓ Question 4: Do you spend more than 2 hours a week searching for information?

❓ Question 5: Do you often make decisions based on "gut feeling" rather than facts?

If you answered "no" or "unsure" to any of these, your information system is working against you.

What Happens Without a System?

Missed Opportunities

You can't prove your impact to donors

Bad Decisions

You guess instead of knowing

Wasted Time

Hours spent searching for documents

Common Myths -Busted

❌ "I need expensive software."

❌ "It's just for tech people."

🚀 Start Today: Your First 3 Steps

Step 1 Choose ONE thing to track consistently :-sales, expenses, or production numbers. Just one.

Step 2 Pick a simple tool :- a notebook, a spreadsheet, or a free app. Use it every day for 7 days.

Step 3 Review your data at week's end :- What did you learn? What surprised you? Let that inform one decision.

That's it. That's the beginning of your information system.

🤔 Take a Moment to Reflect

What's one piece of information you track that could be more organized?
What's one decision you make regularly that would improve with better data?
What's one small change you can make this week to start building your system?

Write down your answers. They're your starting point.

✨ A Final Word

Eyerus and Tsegaye started in the same place. Same market. Same work. Same challenges.

The difference wasn't talent or luck.

The difference was a system.

Tsegaye decided his information would work for him, not against him. He started small. He stayed consistent.

You can make that same choice today.

Start now. Your future self will thank you.
