Abstract

A method for predicting and quantifying risk in information technology (IT) service contracts includes comparing features of a new IT service contract with similar features from one or more previous IT service contracts selected from a plurality of previous IT service contracts to calculate a similarity value between each pair of the new IT service contract and one of the one or more previous IT service contracts, aggregating the similarity values, and using the aggregated similarity values with a prediction model to predict risk factors affecting the new IT service contract and to quantify an impact of each predicted risk factor on an expected gross profit margin.

Description

BACKGROUND

1. Technical Field

The present disclosure is directed to systems and method for predicting and quantifying contract risk for information technology (IT) service contracts.

2. Discussion of Related Art

Information technology (IT) service contracts allows clients to contract the operation of IT systems and processes to a specialized service provider, so the clients can focus on their core business functions. As such, service providers strive to provide uninterrupted, high quality delivery of service to achieve high levels of client satisfaction, while at the same time maintaining continuous contract profitability.

In practice, a significant number of new service contracts financially underperform when compared to the original budget and plan. This is because service providers often need to make a decision about whether to undertake a contract without having proper access to the client's IT environment to understand potential risks. During an engagement phase prior to contract signing, clients are often reluctant to reveal critical or precise information about their IT operations as there is no guarantee that the service provider they are negotiating with would eventually be the one who takes over their operations.

Contract risk prediction and quantification is a major challenge that IT service providers face today. Service providers need to know about the potential risks for a given new opportunity ahead of contract signing to (1) make educated decisions about whether to undertake the IT operations of a potential client, (2) be proactive about mitigation planning if they are willing to take on a risky contract, and (3) price the contracts accordingly to account for risks that cannot be mitigated.

Another reason for poor financial performance in the early stages of a contract is often the lack of a quantitative approach to objectively evaluate risk impact and prioritize risk management tasks. Existing risk management processes have limitations. Service providers often need to decide on a contract with limited access to the client's IT environment without thoroughly understanding potential risks. Although many risks can be identified at engagement, there are frequently too few resources to manage them all. Even if risks are known ahead of time, it may not be possible to quantify their impact, which makes it difficult to put price contingencies in contracts should the service provider decide to take on a risky contract. Previous research on impact quantification has mostly focused on high level IT risks and associated costs rather than quantifying contract risks at a fine level of granularity.

BRIEF SUMMARY

According to an aspect of the invention, there is provided a method for predicting and quantifying risk in information technology (IT) service contracts that includes comparing features of a new IT service contract with similar features from one or more previous IT service contracts selected from a plurality of previous IT service contracts to calculate a similarity value between each pair of said new IT service contract and one of the one or more previous IT service contracts, aggregating the similarity values, and using the aggregated similarity values with a prediction model to predict contract profitability and risk factors affecting the new IT service contract and to quantify an impact of each predicted risk factor on an expected gross profit margin. The previous contracts include existing contracts and historical contracts no longer in force. The prediction model recommends mitigating actions for each predicted risk factor.

DETAILED DESCRIPTION

Exemplary embodiments of the invention as described herein generally include systems and methods for using risk prediction models to predict potential contract profitability, relevant contract risks and their impact. Accordingly, while embodiments of the invention are susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit embodiments of the invention to the particular forms disclosed, but on the contrary, embodiments of the invention cover all modifications, equivalents, and alternatives falling within the spirit and scope of the disclosure.

A financial risk analytics according to embodiments of the present disclosure can enable quality analysts and risk managers to learn about and proactively manage potential contract risks before they materialize, while also providing guidance to contract pricers to include the necessary cost contingencies into pricing considerations, in case of a high risk contract. Financial risk analytics (FRA) includes predictive models built from historical contract data and observed risks, and provides insights on contract profitability as well as potential risks and their impact for a given new opportunity ahead of contract signing. FRA, thus, enables service providers to make educated decisions about whether to undertake the IT operations of a potential client, or proactively mitigate risks for service providers that are willing to take on a risky contract. Finally, service providers can use FRA insights to adjust contract prices according to the predicted risk impact, if risk mitigation is not feasible.

A financial risk analytics (FRA) tool according to an embodiment of the disclosure can provide predictive models to shed light into potential contract risks and quantify their impact, while also recommending mitigation actions for proactive risk management. FIG. 1 depicts an overview of a financial risk analytics tool according to an embodiment of the disclosure. Prior to the engagement phase, a predictive model according to an embodiment of the disclosure needs at least three types of training data from historical contracts:

(1) Various risk assessments from historical contracts, such as technical, contract and client risk assessments, as well as differentiating characteristics of contracts, which altogether form a contract fingerprint. Characteristics that differentiate contracts include, but are not limited to, geographic locations of IT service contract providers and clients, an industry of the client, total contract value, contract specifics, such as the type of transformation that will be performed on the client's IT environment, e.g., whether the IT service provider will take over the operation of the client's datacenters or not, etc, and the cost case. Each feature in a contract fingerprint can be converted into a numerical or categorical value. For example, risk managers or quality assurance specialists can answer risk assessment questions using one of N/A, Low, Medium, High and Exceptional, which can be mapped to numeric values as N/A=0, Low=1, Medium=2, High=3, Exceptional=4, for use in calculations.

(2) Risk root causes observed from contract reviews for these historical contracts during transition or delivery. Examples of root causes include, but are not limited to, inaccurate staffing plans, inadequate transition plans, committed service delivery time not achievable, client responsibility not fulfilled, etc.

(3) The financial performance of the historical contracts, namely the actual performance compared to the original plan.

Both the root cause analysis data and the financial data can be quantified, and this quantified data is correlated with the contract fingerprint. Trained with the above data, a predictive model according to an embodiment of the disclosure can, for a new contract, based on its fingerprint, (1) calculate probabilities of attaining a range of predicted GP percentages, from which the model can predict whether a new contract is likely to meet the profit target, and if not, miss by how much; (2) breakdown potential risks along with their likelihood of happening and financial impact; and (3) recommend mitigation actions for proactive management of the predicted risks. In the example shown in FIG. 1, a predictive model according to an embodiment of the disclosure can provide a price case gross profit (GP) percentage without contingency of 20%, a predicted risk exposure of 1.5%, and a realistic GP margin of 18.5%.

An FRA's predictive model according to an embodiment of the disclosure is based on a similarity measure between contracts. FIG. 2 illustrates how contract similarity can be used to provide predictions for a new contract. That is, a prediction for a given new contract is based on a measurement of similarity between the new contract and a set of historical contracts, based on their fingerprints. Referring to FIG. 2, for each contract taken from a pool of existing/historical contracts, the contract characteristics, observed GP deltas (the difference between the predicted and actual GP percentage), and reported root causes will be compared with corresponding features of the new contract, and the results of these comparisons will be aggregated, weighted by the similarity of each existing contract to the new contract, to yield a set of predictions. The details of contract similarity measure will be provided below. With this definition, an FRA predictive model according to an embodiment of the disclosure can then provide (1) a contract profitability prediction; (2) a risk prediction; and (3) recommended mitigation actions for each predicted risk. In the example shown on the right side of FIG. 2, an FRA predictive model can predict the total risk exposure to the GP margin, predict the impact in percentages of individual risks on the GP margin, and for each risk, list recommended mitigation actions.

Contract Similarity

In a prediction model definition according to an embodiment of the disclosure, two contracts are similar if they have similar contract fingerprints. A historical contract data set according to an embodiment of the disclosure includes more than 300 features in each contract fingerprint, although not all features are equally important or useful for risk predictions. To ensure that the more significant features provide a greater contribution to the similarity measure, higher weights are assigned to them. Since a goal of determining contract similarity is to predict risks, weights are assigned to features based on their correlation with the actual similarity between a pair of contracts, in terms of their reported risks.

FIG. 3 presents pseudo-code for a method for determining contract similarity, according to an embodiment of the present disclosure. To calculate a weight w_f for each feature f, one computes a Pearson's Correlation between risk distances and feature distances. The stronger the correlation, the higher weight will be assigned to feature f.

Referring to FIG. 3, risk (root cause) distances for all contracts are computed at step (i) by comparing the risks for each pair of contracts and calculating the difference between these risks, denoted by dist_r. According to an embodiment of the invention, a measurement of risk distances can be calculated between any pair of known contracts based on the overlap of their risks. In essence, if contract 1 has N risks and contract 2 has M risks, and they share X risks, then their risk distance is x/(N+M−x), a value between 0 and 1. Similarly, feature distances are calculated for all historical contracts in step (ii), denoted by dist_feature, by comparing the features for each pair of contracts. According to an embodiment of the invention, feature distances can be calculated between any pair of known contracts by taking a difference of their features. In other words, given contract 1 feature 1 (c₁f₁) and contract 2 feature 1 (c₂f₁) (i.e., the same feature for both contracts), then (c₁f₁-c₂f₂)/(maxf₁Value-minf₁Value) yields a normalized value between 0 and 1, indicting a feature distance of contracts 1 and 2.

The Pearson's Correlation coefficient is calculated based on the values of (i) and (ii) at step (iii), which, after normalization, is used as a weight (w_f) for each feature. Given a target opportunity i, based on the vector of weighted features, i.e., the weighted fingerprint, the Euclidian distance, denoted Dist(i,j), between the target opportunity and each historical contract is calculated in step (iv) by summing over all features the feature distance between each pair of contracts being compared weighted by the Pearson's Correlation coefficient for the feature. The final step is to calculate contract similarity Sim(i,j) between the target opportunity i and each historical contract j from the Euclidian distance Dist(i,j), as shown in step (v).

Predicting GP Delta

According to an embodiment of the present disclosure, contract profitability is measured using the change in the gross profit margin, referred to as a GP delta, which is determined by subtracting from the planned GP % the actually observed GP % for a given contract:

GP Delta=GP Plan−GP Actual.

FIG. 4 illustrates a method for measuring contract profitability, according to an embodiment of the present disclosure. Referring to FIG. 4, an approach according to an embodiment of the disclosure for predicting contract profitability builds an ordinal regression model at step 1 by regressing fingerprints of the historical contracts (x₁ through x_N) as the independent variables against several pre-defined buckets of observed GP delta ranges from historical contracts as the dependent variables, where the optimal range (r_{a1 to K}, r_{b1 to K}) of buckets (bk_{1 to K}) are determined based on the historical distributions and expert input.

At step 2, once a regression model according to an embodiment of the disclosure is in place, given a new opportunity and its fingerprint, the regression model yields a set of (bucket, probability) pairs that define the probability of the GP delta prediction falling into a specific bucket. For example, a prediction could yield an 85% probability that the GP delta will fall into bucket [0, 5] which would mean a positive GP delta, indicating that the predicted profit margin is 0 to 5% higher than the plan. Finally, at step 3, an expected value for GP delta is calculated by multiplying the mid-points of the ranges, assuming a uniform distribution within the range, by the respective probabilities (p_i) of the GP delta falling in that bucket, and summing the products:

$E\left(GP\mathrm{Delta}\right]=\sum _{i=1}^K\frac{1}{2}p_i\times \left(r_{\mathrm{ai}}+r_{\mathrm{bi}}\right).$

While a regression model according to an embodiment of the disclosure as shown in FIG. 4 provides a good prediction on GP Delta range when tested against historical contract data, other embodiments of the disclosure further incorporate contract similarity with a regression model according to an embodiment of the disclosure to provide a more fine-grained prediction on GP Delta.

In an extended model according to an embodiment of the disclosure, illustrated in FIG. 5, the result of the regression model is treated as a direction indicator. For a given new contract, the aforementioned regression model is used to determine which range the GP delta is most likely to be in, e.g., [0, 5] with 85% probability.

Next, a GP delta of the new opportunity, GP Delta_SR, is predicted by taking a weighted average of the GP deltas of the similar historical contracts, whose GP deltas fall into that particular (say [0, 5]) bucket, where the weights refer to contract similarity, which is normalized to have values in the range [0, 1], as shown in FIG. 5:

$GP{\mathrm{Delta}}_{\mathrm{SR}}=\frac{\sum _{i=1}^NGP{\mathrm{Delta}}_i\times {\mathrm{Similarity}}_i}{\mathrm{totalSimilarity}\left(1,N\right)},$

where totalSimilarity(1,N) is a sum of the Similarity's for each i, where i refers to a similar contract within the bucket range [r_ai, r_bi] predicted by a regression model according to an embodiment of the present disclosure where a contract similarity threshold=x %.

Risk Prediction and Quantification

For a service provider, knowing that a given opportunity is likely to become unprofitable is often not enough. Service providers also need to know what the potential risks are as well as how to quantify these potential risks to be able to mitigate them before they materialize.

Risk prediction and quantification can also benefit from a contract similarity determination according to an embodiment of the disclosure, as shown in FIGS. 2-3. A method of predicting and quantifying risk according to an embodiment of the disclosure is shown in FIG. 6. Given a target opportunity i, a set of similar contracts j are determined along with a degree of similarity Similarity(i,j)=1−Dist(i,j) [0 through 1], as shown in step 1. The Similarity(i,j) can be determined using a method such as that shown in FIG. 3.

For each reported risk (or root cause) of a historical similar contract, the potential impact can be calculated by dividing the GP Delta of this similar contract by the number of risks observed for this similar contract. Note that this is an approximation due to a lack of more accurate impact assignment data at the time of building the model, and can be improved if a risk management process according to an embodiment of the disclosure assigns certain impact values to each reported risk. A weighted average of all calculated impacts for this particular risk observed across all similar contracts is calculated such that the weight is determined by the degree of contract similarity (step 2):

${\mathrm{r\_impact}}_k=\frac{\sum _{j=1}^N\left(\left(GP{\mathrm{Delta}}_j/{\mathrm{numberOfRisks}}_j\right)\times \mathrm{Similarity}\left(i,j\right)\right)}{\mathrm{TotalSimilarity}\left(1,N\right)}.$

The probability of risk k for target opportunity i is calculated at step 3 by taking a weighted average of the number of occurrences across all similar contracts such that the weight is, again, determined by the degree of contract similarity:

${\mathrm{r\_probability}}_k=\frac{\sum _{j=1}^N\mathrm{Similarity}\left(i,j\right)}{\mathrm{TotalSimilarity}\left(1,N\right)}.$

FRA Tool

FIG. 7 shows a screenshot of an exemplary FRA tool implementation according to an embodiment of the disclosure. The following data from historic contracts is used to train a prediction model according to an embodiment of the invention: Client Risk Assessments; Technical Risk Assessments; Contract Risk Assessments; Reported Risks (Root Causes); and Financials. An FRA tool according to an embodiment of the disclosure can provide predictive analytics using regression and similarity, and for a new client, can predict contract profitability and potential key risks that are likely to materialize.

To use a tool according to an embodiment of the invention, a user first selects a Geography and a Sector to narrow down the set of available opportunities to analyze ahead of contract signing, and then selects a contract opportunity of interest. Once the opportunity of interest is selected, e.g., Customer X, contract details are shown, and the user can press the Run Prediction button to display the results of an FRA according to an embodiment of the invention.

An FRA tool according to an embodiment of the disclosure can predict the contract profitability (GP Delta) as well as a predetermined number of top potential risks for the target opportunity. For example, for Customer X, FIG. 7 shows that FRA predicts a GP Delta of −38.2 points, indicating a 38.2% less profitability than the plan, and the top 15 potential risks. For each predicted risk, FRA also displays a probability, represented by the horizontal bar on the right side of the figure. For example, risk D has an 8% probability of happening for the selected target opportunity (Customer X). The user can click on the bar to display further risk details. Customer names, dates and particular risk details in FIG. 7 have been anonymized for confidentiality reasons.

Selecting a particular risk from the top 15 list reveals more information about that risk, as shown in the screenshot of FIG. 8. The additional risk details include a risk description, a probability of occurrence and its impact.

For example, the screenshot of FIG. 8 reveals additional information for Risk D after the user has selected it through the interface shown FIG. 7. In addition to more detailed description of Risk D, FRA also shows the probability (8%) and the potential impact (−3.6 points) of that risk for the target opportunity.

Another important step in risk management is risk mitigation. For each predicted risk, FRA can show a set of mitigation steps the user can take to proactively manage that risk before it materializes.

Finally, the user can be presented with a set of similar historical contracts along with their observed risks to enable a more detailed investigation of potential risks, if needed.

Detailed risk definitions, associated mitigation steps and similar contract names In FIG. 8 have been anonymized for confidentiality reasons.
