Solu­tion design: Cre­at­ing a solu­tion that dri­ves real impact

This sec­tion is for you if …

  • you’re plan­ning to launch an impact start­up – or already deep in the process with your team.
  • you know what prob­lem you want to solve, along with its caus­es and effects
  • you under­stand your tar­get group, their needs, and the oth­er stake­hold­ers involved.
  • you’ve cre­at­ed a per­sona or a rep­re­sen­ta­tive pro­file of your tar­get group.
    .

In this sec­tion, you’ll learn how to …

  • devel­op inno­v­a­tive approach­es to tack­le a social chal­lenge.
  • build hypothe­ses about the impact poten­tial of your ideas.

Review exist­ing solu­tions and iden­ti­fy oppor­tu­ni­ties for inno­va­tion

Many social chal­lenges already have solu­tions – devel­oped and imple­ment­ed by bold, com­mit­ted peo­ple. If you’re famil­iar with these solu­tions, you can adopt spe­cif­ic aspects or fill the gaps they leave behind.

1. Do your research

Start by explor­ing exist­ing solu­tions, ini­tia­tives, and projects relat­ed to your prob­lem. Look into gov­ern­ment pro­grams, non­prof­its, pri­vate ini­tia­tives, tech-based approach­es, and local efforts. The goal is to under­stand what’s already being done – and what’s miss­ing.

2. Use a SWOT analy­sis to eval­u­ate exist­ing solu­tions

Ana­lyze how exist­ing solu­tions work: Who do they reach? How effec­tive are they? What impact have they had?

A SWOT analy­sis can help you iden­ti­fy strengths and weak­ness­es, spot oppor­tu­ni­ties, and under­stand the risks. Here’s how to apply it:

  • Iden­ti­fy strengths: What does this solu­tion do well? What sets it apart? Why has it been suc­cess­ful?
  • Iden­ti­fy weak­ness­es: Where are the gaps or chal­lenges? What could be improved? What lim­its its impact?
  • Iden­ti­fy oppor­tu­ni­ties: Exam­ine the exter­nal fac­tors that can have a pos­i­tive impact on your solu­tion. What trends, tools, or part­ner­ships could make it even stronger? Is there poten­tial for scal­ing or improve­ment?
  • Rec­og­nize risks (threats): What risks could under­mine its suc­cess? Are there com­peti­tors, fund­ing gaps, or neg­a­tive trends that might get in the way?

3. Devel­op at least two solu­tion ideas

Look for areas where new approach­es can close gaps or push the field for­ward. These could include new tech­nolo­gies, cre­ative busi­ness mod­els, or fresh part­ner­ships. Maybe there’s an exist­ing idea that hasn’t been tried in your region – that could be your start­ing point.

Cre­ate at least two solu­tion ideas that dif­fer in one key aspect. This allows you to com­pare them lat­er with your tar­get group. For each ver­sion, write a clear hypoth­e­sis about why it might work bet­ter. That way, you’ll be able to test and learn which approach has the most impact.

First steps toward a poten­tial busi­ness mod­el

At this stage, you should start think­ing about how to dis­tin­guish between your cus­tomers (those who pay for the solu­tion) and your tar­get group (those who ben­e­fit from it). This dis­tinc­tion is espe­cial­ly impor­tant for social enter­pris­es and impact star­tups, since the peo­ple who ben­e­fit aren’t always the ones foot­ing the bill.

Real-world exam­ples:

Cus­tomers and tar­get group are the same
An app designed to sup­port peo­ple with depres­sion: Users pay for access to the app’s fea­tures and direct­ly ben­e­fit from tools like ther­a­py mod­ules, mood track­ing, and peer sup­port net­works. In this case, the pay­ing cus­tomer and the tar­get group are one and the same.

Cus­tomers and tar­get group are dif­fer­ent
A com­pa­ny that makes sus­tain­able water fil­ters for use in devel­op­ing coun­tries: Here, the cus­tomers are aid orga­ni­za­tions or gov­ern­ments that pur­chase the fil­ters. The tar­get group is the local pop­u­la­tion, who gains access to clean drink­ing water. In this case, a third par­ty pays for the solu­tion on behalf of the peo­ple who ben­e­fit from it.

The tar­get group is part of the val­ue chain
A cof­fee com­pa­ny wants to sell fair­ly trad­ed, sus­tain­ably pro­duced cof­fee in Ger­many. It ensures eco-friend­ly farm­ing prac­tices, fair wages, and safe work­ing con­di­tions, while keep­ing trans­port as sus­tain­able and short as pos­si­ble. In this mod­el, impact is cre­at­ed across the val­ue chain, and the cus­tomer in Ger­many pays for the prod­uct.

If none of these mod­els apply
Think about how you can still cre­ate impact. That might include donat­ing a share of your rev­enue or part­ner­ing with one or more non­prof­its. But make sure your prod­uct or ser­vice also meets high sus­tain­abil­i­ty stan­dards on its own.

This chart high­lights key ques­tions to help you start devel­op­ing a busi­ness mod­el. Your mod­el can com­bine mul­ti­ple strate­gies.

Align your solu­tion with cus­tomer needs

The val­ue propo­si­tion can­vas helps make sure your solu­tion tru­ly fits your cus­tomers. It has two parts: the cus­tomer side and the offer­ing side. If your busi­ness cre­ates direct impact for your cus­tomers, you’ve already worked through the cus­tomer side while ana­lyz­ing the prob­lem, your tar­get group, and key stake­hold­ers.

If you real­ize in this step that your cus­tomers are actu­al­ly a third par­ty help­ing you cre­ate impact, go back and fill out the cus­tomer side of the val­ue propo­si­tion can­vas again. Then move on to the offer­ing side. This includes:

  • Prod­ucts and ser­vices: List what you offer. Include every­thing your impact start­up pro­vides – both tan­gi­ble and intan­gi­ble, like com­mu­ni­ty or sup­port.
  • Prob­lem solvers (pain reliev­ers): Show how your solu­tion helps solve the customer’s prob­lems. Make sure these are tai­lored to the spe­cif­ic pain points you’ve iden­ti­fied. Focus on solv­ing the biggest one.
  • Gain cre­ators: Explain how your solu­tion adds val­ue and makes life bet­ter for your tar­get group. What ben­e­fits do they get? Go beyond func­tion­al­i­ty – think about emo­tion­al con­nec­tion and loy­al­ty too.

In the end, com­pare both sides. The val­ue propo­si­tion can­vas is a tool you’ll come back to again and again. Review­ing and refin­ing it helps make sure your solu­tions stay effec­tive.

Test the impact poten­tial of your ideas with the Impact Lad­der

To build an impact-dri­ven busi­ness, you need an impact log­ic that shows how your activ­i­ties lead to long-term out­comes. The impact lad­der helps you to clear­ly for­mu­late your mea­sures and goals. It shows the indi­vid­ual stages — from the inputs (resources), through the activ­i­ties, to the results and long-term effects. Try to fill the impact lad­der from top to bot­tom.

A range of impact mod­els

There are sev­er­al ways to struc­ture your impact log­ic – like the IOOI mod­el, The­o­ry of Change, LogFrame, or the impact chain. In this play­book, we use the Impact Lad­der.

1. Fill in the Impact Lad­der for your solu­tion ideas

Now it’s time to test whether your ideas can solve the social prob­lem you’ve iden­ti­fied and cre­ate the impact you’re aim­ing for. Work through each step of the impact lad­der to map your log­ic. Start with Step 1:

Step 1: Activ­i­ties take place as planned (out­put)
Define the con­crete actions or activ­i­ties need­ed to imple­ment your idea. These are your first out­puts and the foun­da­tion for every­thing that fol­lows. Ask your­selves:
What spe­cif­ic activ­i­ties do we need to car­ry out?

Step 2: Tar­get group is reached (out­put)
Esti­mate how many peo­ple in your tar­get group you’ll reach with your solu­tion. This is anoth­er out­put and a key met­ric for mea­sur­ing your project’s suc­cess. Ask:
How many peo­ple in our tar­get group do we want to reach with our solu­tion?

Step 3: Tar­get group engages with the solu­tion (out­put)
Define how you expect your tar­get group to accept and use your solu­tion. This step is cru­cial to under­stand­ing how your idea cre­ates change. Ask:
How should our tar­get group respond to and engage with our offer­ing??

Step 4: Aware­ness or skills of the tar­get group change (out­come)
Describe the knowl­edge, atti­tudes, or skills your tar­get group should gain. This is where impact begins – these are mea­sur­able out­comes that track progress. Ask:
What spe­cif­ic knowl­edge, mind­set, or skills should our tar­get group devel­op?

Step 5: Tar­get group changes behav­ior (out­come)
Define what new behav­iors you expect to see in your tar­get group. Behav­ior change is a key mile­stone on the way to deep­er out­comes. Ask:
What con­crete actions or behav­iors should change with­in our tar­get group?

Step 6: The tar­get group’s liv­ing con­di­tions change (out­come)
Describe how your solu­tion improves the liv­ing con­di­tions of your tar­get group. This is the core out­come of your work. To define it clear­ly, ask:
What spe­cif­ic improve­ments in their lives are we aim­ing for?

Step 7: Soci­ety changes (impact)
Spell out your long-term goal – the broad­er soci­etal change you want to help cre­ate. This is the ulti­mate impact. Ask:
What long-term change in soci­ety are we work­ing toward?

Once your Impact Lad­der is in place, think about the resources, means and inputs you’ll need to car­ry out your activ­i­ties. That includes fund­ing, staff, mate­ri­als, tech­nol­o­gy, as well as knowl­edge and net­works.

One Impact Lad­der per tar­get group

You’ve iden­ti­fied mul­ti­ple tar­get groups for your solu­tion? In that case, it’s best to cre­ate a sep­a­rate impact lad­der for each group. Then look close­ly at where these lad­ders inter­sect or over­lap. That said, try to keep the num­ber of tar­get groups as small as pos­si­ble – oth­er­wise, your impact log­ic may lose focus.

Next chap­ter: Test your solu­tion ideas

You’ve made real progress: you’ve devel­oped inno­v­a­tive solu­tions to address your prob­lem and built an Impact Lad­der.

The next step is to test your ideas with your tar­get group to see if they hold up in prac­tice. That’s what we’ll tack­le in the next chap­ter.
