leading to cost savings?
- Today – sneak preview of initial results

- Joint Research - Z/Yen Limited & CASS Business School Centre for
Charity Effectiveness
- Can predictive techniques inform the decisions of grant-making bodies and
thus improve their effectiveness?
- Participants: New Opportunities Fund and City Parochial Foundation
- Authors of forthcoming papers
- Ian Harris & Michael Mainelli (Z/Yen)
- Peter Grant & Jenny Harrow (CASS CCE)
- Today – work in progress

- Multi-dimensional correlation (a.k.a Support Vector Machine maths)
- Helps to spot patterns and identify anomalies in data
- Classification and prediction
- PropheZy can be used to make predictive applications using readily
available data
|
|

|
- Commercial applications include:
- Television audience and time predictions
- Managing trade execution rates (with London Stock Exchange)
- Reducing failed trades for major investment banks
- Price-your-audit tool and studies
- Potential charity applications:
- Identify best fundraising techniques, bid approaches or cross-sales
- Set targets for donor revenue, profitability, bid success, satisfaction
- “Fill in the blanks” on donor data
- Increase success rates among targets, reduce churn
- Improve assessment of grant applications

- Test PropheZy ability to improve fundraising approach, e.g.,
- Are some people being mailed who are unlikely to ever respond?
- Are there defining characteristics for those who will respond?
- Are we failing to mail people who should be targeted?
- Work with National Fundraising Charity’s database
- Including ~ 250,000 records of active warm donors in last 3 to 5 years,
excluding committed givers
|
|
12
|
- Training Set (cast) included: Gender, Postcode, Contact history, Date of
Birth, Campaigns Mailed, response to campaigns
- Test set (forecast): aim to predict responses to September 2004 campaign
- Iterative approach, refining and developing questions, allowing PropheZy
to cope with charity hit rate
|
|
13
|
- Series of tests based on responses to 3 to 15 mailings
- PropheZy can identify response rates with up to 90% accuracy
- Most accurate for Yes/No response, more difficult with different
response levels
- Best results by excluding those with no contact history
|
|
14
|
- Test includes history of one year’s mailings (excluding those with no
history)
- Comparing “Zero responses” with “Responses”
- Of the predicted responses:
- 61% were correctly identified – have the characteristics of givers
- 37% had not responded – potentially have the characteristics of givers
- 5% had not been mailed – Charity did not believe they had
characteristics of givers, but PropheZy does

- PropheZy identifies three groups for further investigation:
- Farmland (61%): targets who give, and may have the characteristics of
committed givers
- Rocky Soil (37%): targets who did not respond, but worth investigating
to find if they would ever respond
- Hunting Ground (5%): targets who were not mailed but have the
characteristics of those who should respond
|
|
19
|
- Farmland: up to 5,000 additional committed givers
- Rocky Soil: An additional 2,300 responses could increase donations by
£30,000 OR provide savings by not mailing them
- Hunting Ground: at least 150 additional donors, previously considered
“cold”
|
|
20
|
- Tests show groups worth investigation:
- Farmland: consider approaching actively as committed givers, saving
money on direct mail, and increasing lifetime value
- Rocky Soil: potential to increase income or make significant savings
following further research to find why they don’t respond (e.g.,
returns)
- Hunting Ground: begin active fundraising relationship
- Further research underway, e.g.,
- Seasonality
- Predicting value of donations
|
|
21
|
- Reduced costs – printing, postage etc
- Improved relationships – more effective targeting
- Potential for growth in committed givers
- Enhanced data quality “Fill in the gaps”
|
|
22
|
- Three post hoc evaluation questions:
- Did the funded work mostly achieve its objectives?
- Was it the right decision to have funded?
- Did you fund again / would you recommend funding again?
- Look at all readily accessible applications data stored for each fund
|
|
23
|
- City Parochial Foundation
- all grants awarded in 2000
- 50 “training set”
- Remainder (c150) “test set”
- New Opportunities Fund
- 3 programmes – Community Access to Lifelong Learning, Digitisation
& Healthy Living Centres
- 150 “training set” (50 from each)
- Remainder (c1500) “test set”
|
|
24
|
- Where PropheZy flags up anomalies (i.e. “no answers”), test whether that
result concurs with those of evaluators
- City Parochial insufficient no answers to enable prediction on that
volume of data – asked evaluators to rank projects A, B or C instead
- New Opportunities Fund did generate sufficient no answers to spot 30
potential anomalies on the test set for one fund
|
|
25
|
- Even with the ABC ranking rather than yes/no answers, PropheZy couldn’t
find anomalies in the City Parochial Data
- Possibly down to sample size and the relatively limited amount of data
stored for each grant at City Parochial
- Hands-on evaluation on application c/w process-based application methods
|
|
26
|
- Of the 30 potential anomalies PropheZy found at nof, 50% were confirmed
to indeed be problematic grants
- The training population, a random sample from the whole population, had
18% anomalies (26/141)
- A 50% “hit rate” is statistically significant at 99.9% confidence, on
this sample size
- These results are very encouraging

|
- Where sample size is large enough and procedural methods are used for
most applications, predictive methods could flag up potential problem
grants in advance of funding
- As predictive tools of this kind learn from additional training data,
the hit rate could improve to well above 50%:50%
- NOT a substitute for other methods – should not base decisions on this
alone
|
|
31
|
- Initial scepticism – is grant making an art, or a science?
- Issues with data – concern about subjective responses
- Concerns about timescales – what is correct timescale for evaluating a
piece of work?
- Emphasise that techniques cannot
replace the human element
|
|
32
|
- Public grantmakers: Encouraged to demonstrate accountability
- High volume grants with human resources at premium: Process based
evaluation of applications
- Organisational rather than project investment: where investments aim
to meet programme aims
- ‘Social return on investment’: developing venture philanthropy
|
|
33
|
- Coping with floods of rapidly changing information
- Static MIS not good enough
- Seeking robust, general-purpose tools suitable for many datasets
- Seeking quantitative ways of assessing outcomes
- Moving from analytics to action
|
|
34
|
- Needs further work on visualisation (outputs as well as inputs)
- Further refinement of data and tests with other organisations
- Keen to do further work with other charities
