A Theory of Scrum Team Effectiveness: Dataset and Supplementary Materials

This bundle contains supplementary materials for an upcoming academic publication A Theory of Scrum Team Effectiveness, by Christiaan Verwijs and Daniel Russo. Included in the bundle are the dataset, SPSS syntaxes, model definitions (AMOS), and supplementary tables. 

About the dataset

The dataset (SPSS) contains anonymized response data from 2.939 respondents from 1.193 Scrum Teams that participated from the scrumteamsurvey.org. Data was gathered between June 3, 2020, and May 19, 2021. We cleaned the individual response data from careless responses and removed all data that could potentially identify teams, individuals, or their parent organizations. We concluded that data was missing completely at random (MCAR, Chi2= 8,425.128,df= 8,592,p=0.899), so multiple imputation was used in SPSS to impute missing values. Finally, we aggregated all individual response data to the team level by calculating mean-based averages for the variables.

The dataset contains question labels and answer option definitions. To conform to the privacy statement of scrumteamsurvey.org, the bundle does not include response data from before the team-level aggregation. If researchers specifically want to replicate the process of cleaning, imputing, and aggregating data, they can contact the authors.

About the model definitions

The bundle includes definitions for Structural Equation Models (SEM) for AMOS. We added the four iterations of the measurement model, four models used to perform a test for common method bias, the final path model, and the model used for mediation testing. Mediation testing was performed with the procedure outlined by Podsakoff (2003). Mediation testing was performed with the "Indirect Effects" plugin for AMOS by James Gaskin.

About the SPSS syntaxes

The bundle includes the syntaxes we used to prepare the dataset from the raw import, as well as the syntax we used to generate descriptives. This is mostly there for other researchers to verify our procedure.

About the supplementary tables

The bundle includes an Excel file with supplementary tables:

1. Sample descriptives
2. Variable definitions
3. Questionnaire
4. Model fit
5. Means, standard deviations & correlations for first-order latent factors
6. Parameter estimates for the final path model
