Our research objective:Optimize cross-company cooperation
Optimize cross-company supply chains (SC)– Technical factors influencing performance of SCs– Human Factors influencing performance of SCs– Interface Factors on SCs performance– Interrelationship of technical, interface, and human factors
Why are humans considered?– Humans make final decision– Overview over not explicitly modelled relationships
(e.g., closed-world assumption)– Complexity and uncertainty increases,
less time for making decisions

Development of business simulation game Extends „Beer Distribution Game“ Based on System Dynamics model Includes product quality
– Product intact or broken– Supplier's quality varies– Internal production quality varies
Increased complexity (tradeoff 3 parallel tasks)– Management of stock levels– Investment in incoming goods inspection– Investment in internal quality management
Over 20 variables in the user interface Players must infer state of the production
Part of the game’s simulation model:Stock level at a given time t:S(t) = S(t-1) + O(t-1) – D(t)
Net profit:P(t) = R(t) – cStock×S(t) – Iigi(t) –

Determinants for Increased Game Interaction
The number of changes to the controls in the game varied from 3 to 39 (mean 22.6±10.6, median 22).
Self-efficacy in interacting with technology single explanatory variable influencing the number of changes. People with higher SET did significantly more changes [ρ=.367, p=.028<.05].

Determinants for Performance Most independent variables did not relate to the achieved Performance in the game. Only the attitude towards serious games ASG [ρ=-.327, p=.051<.1] and the need for
achievement NA [ρ=-.329, p=.050<.1] had a negative influence of performance.

Determinants for Acceptance
Strong positive relationship of most variables on the intention to use the game (BI).
The three strongest influencing factors:– Performance Expectancy PE [ρ=.790]– Transfer of Skills TOS [ρ=.747]– Hedonic Motivation HE [ρ=.619]
No influence on BI by:– Facilitating Conditions FC– Social Influence SI– Learner Control LC– Situated Learning SL

RWTH Aachen University, Human-Computer Interaction Center
Determinants for Acceptance
Due to small sample size the application of multiple linear regressions yielded only in a single significant model for the user factors and for the models’ factors:
– User Factors: Attitude towards serious games (ASG) single predictor for intention to use the game, explaining 61.7% of the variance in BI (r2=.617, β=.792)
– Model Factors: Performance Expectancy (PE) explains 59.2% (r2=.592, β=.778) of the variance in BI.

Subsumption and Outlook
Overall acceptance of serious games for conveying knowledge of production planning and control and quality management was high.
Combination of the UTAUT2 and the SG-TAM model to investigate the acceptance of the QM-Game and business simulation games in general seems to be very promising:
– both models complement each other and may in combination contribute more explained variance in BI and later USE than each individual model.
Further studies needed to research isolated influence of interwoven factors

page 26
P. Brauner et al. – "Projecting Efficacy and Use of Business Simulation Games in the Production Domain using Technology Acceptance Models" - AHFE 2016
Priority Guideline
1Provide clearly visible short-term benefits of using the
game. E.g., by making clear that the conveyed skills will be beneficial for an upcoming exam. (Based on PE)
2The player must perceive the presented environment as a
simulacrum of the reality. E.g., by portraying realistic production processes. (Based on TOS)
3Consider learner diversity, especially in regard to different
levels of inclination towards games. E.g., by augmenting the game environment with traditional forms of knowledge dissemination. (Based on ASG)

Priority Guideline
4Create enjoyable learning environments. E.g., by including
potential players in the development to ensure target specific aesthetics and playfulness. (Based on HE)
5Avoid unnecessary complexity of the user interface and the
simulation model, and provide a focused learning experience. E.g., by reducing the perceived effort for mastering the game through guided tutorials, help functions etc. (Based on EE)
6Provide adequate and immediate feedback on the learning
performance. E.g., by linking the learning objectives with the company’s profit or by adding motivational incentives (badges, leaderboards, …). (Based on REW)

Evaluation of user interfaces: Research question:
– Do interfaces influence player’s performance?
Interface optimizations based on user feedback– Better spatial layout– Key Performance Indicators (e.g., stock level)
Method– Study (N=40) with old vs. new interface, surveys
Results– Users preferred revised user interface– Higher profits and higher product quality w. new interface
Conclusion:– Good interfaces crucial for performance
